I'm keen to learn about this fascination with Hepa filtration. Is everyone hypoallergenic all of a sudden? Suffering from hayfever? Filtering the air of a room constantly? Using their vacuums to do the filtering?
When you turn your vacuum Off, you are breathing in the pollen and sub-micron particles that you considered so imperative for your Hepa bag to capture & contain.
Sounds to me as though marketing created a 'need' that never existed before.
Notice how large reusable shake-out bags were discontinued about the same time they told you "You need five layers of disposable filtration"?
Ironically, their greed to sell unnecessary bags, gave Dyson a foot in the door with "bagless".

No way... on direct air uprights at least HEPA is the real deal. I have severe allergies. Yes I am breathing pollen and pollution and dog dander constantly and yes I am miserable almost all day. The vacuum is literally exhausting air particles at super high velocity, quite different than walking around a room with still air. If I use a paper bag I am sneezing for the foreseeable future after vacuuming. And it smells like ass. HEPA is 5000% better. There is little to no fine particle exhaust and minimal odor if any.

HEPA bag are not a gimmick. At the shop whenever we get a bag vacuum that has a paper bag it’s compartment is full of dust where if we get one with a HEPA bag in it there is almost little to no dust in it. I have noticed that the cheaper aftermarket HEPA bags aren’t as good as genuine bags so as long as you buy genuine HEPA bags they work great.

I think you make a decent point, ofcourse HEPA does improve the air filtration and in a clean air vacuum helps protect the motor more but many of these bags are ridiculously priced and don't last as long as you think a $5 bag would last so i agree it gave Dyson and even worse Shark a foot in the door personally I think bags should be alot cheaper then they are and also more common i never see bags in the grocery store and only see off brands in department stores or Walmart so I'm sure that contributes to high prices ofcourse even then it's been proven even with these pricey bags it's still cheaper to mantain and operate a bagged machine though i think in direct air machines yoi co

HEPA seems to fill a legitimate need. I think the real marketing gimmick is the allergies that created the need in the first place. Statistically, rich people who keep themselves and their environments sterile tend to have allergies far more often than normal people who are more 'dirty.' Science has long known that if you're never exposed to a potential allergen, you're almost guaranteed to be allergic to it.

But of course that's just the trend, there are always exceptions.

I use HEPA bags not for the allergen-stopping abilities, but for the performance! It turns out that, generally, synthetic HEPA bags “breathe” a lot more easily than a paper bag would after picking up a given amount of dust. You get noticeably better vacuuming performance from such bags.

As an added bonus, the bag keeps your vacuum cleaner, well, cleaner. Not only are they nearly impossible to tear or burst, but they keep everything downstream of the bag free from dust. If you are trying to preserve an irreplaceable vintage outer bag or a hard-to-service motor, HEPA bags are your best bet.

IMO, they are well worth the money.

I'm genuinely questioning this whole concept.

In our old Electrolux, we used a shake-out dust beg for twenty years or more. It worked just fine. Our carpets weren't dirty. And there were no carpet-washers in those days.

Electrolux recommended we use only genuine Electrolux paper bag inserts, of course, but my mum couldn't afford to keep buying those.

I'm fabricating a large reusable bag (3x small bags sewn together) to fit my Kirby. Just like early Kirbys had. Manufacturers discontinued larger reusables when they realised their mistake, and I'm trying to outwit them. I cannot afford throw-away Hepa bags, nor a £500 Dyson Super Turbo Vortex.

So, to summarise:
Hepa is actually needed by a minority with allergies.
Hepa is preferred by engineers who service motors after years of use and don't want dusty motor-housings (the cost of bags bourne by customers).
Hepa has a perceived benefit in end results, which only a CSI Team could realistically detect - you cannot see pollen and sub-micron particles in carpet.

There must be reduced airflow in order to trap those finer particals? I suspect its a trade-off. Surely some heavier particles must therefore be left behind in the carpet?

Your views have reinforced my suspicion that Hepa is a marketing phenomenon with only minimal benefit, and at huge expense. Much in-line with "Use only VAX shampoo with this machine" and "Use only genuine Hoover bags with the Hoover logo", or we won't honour your warranty.

Their money is in after-market consumables. Pretty much like printer toner cartridges.
I'm not buying-in. 😁

Thanks guys. I appreciate your input.

Hepa/fleece bags are huge improvement.
I don't have allergies, but just the fact that bag compartment stays clean using the hepa bags keeps me using those.
I don't like the idea that paper bags leak dust to the motor. Paper bags also clog when they are half way full. Hepa bags much less so.
Then there is the cost. In the Finland 5 hepa bags cost 10€ (11$).
That is only 2€ (2.2$) per month.

So in my opinion hepa bags are big improvement.

If you would actually use a cloth bag upright for a period of time, say one year. You would understand. The clogging effect of dirt on a bag is what led to the Dyson. It’s all about how the fine dust clogs the bag. Any kind of bag. Bags are the dead end of the airstream. However, that dead end is put off to its greatest length of time by using HEPA bags. Cyclones will never work as efficiently as HEPA bags because cyclones only work efficiently with a constant stream of air. Put the crevice tool on and put it down on a piece of furniture, and you completely change the amount of air flowing into the cyclones. Most of the dust will be sucked up through the Vortx finders and clog the pre-motor filter. Once again, bags are best.

Bags vs rainbow.
I love hepa bags just like fact they get debri into the bag.
I have a e2 rainbow and it's maybe in my head but it feels cleaner.
Compact c9 with HEPA bag has cyclone technology.
I'm wondering opinion on rainbow which filters by water.
I don't know if it cleans better than compact but air is cleaner.
I think probably a wash it's just rainbow has built in air purifier.

Vacuum Bags

Well, the availability of bags is even worse in the UK! You guys are saying you can only find aftermarket bags in grocery stores and supermarkets, well here in the UK we cant find any! Nevermind fleece bags, I would just like to see any bags in the stores, we have none. The only place you can get them are online or for a ridiculously high price in a vacuum repair shop which we have next to none left. But by the way, I use fleece bags in some modern vacuums because they maintain higher suction for longer and that is no gimmick. The suction stays strong until the bag is completely full unlike the paper bags. But some people use fleece bags in old machines which I dont agree with as they were meant to use paper bags as thats all that was around back then.

Seems like bags availability is very different from country to country. In Finland we have a lot of internet stores selling vacuum bags and accessories. Selection of bags is huge. For example I found hepa bags for my vintage 1979 Electrolux. You can make agreement with them and they automatically send certain amount of bags for example once a year.
Very convenient and you always have bags.

Here in Canada, thru Amazon I can get 20 hepa type bags for the Kenmore for 24 Cdn dollars. These bags are cheaper than the paper ones. I have never seen dust on the bags or in the chamber even when almost full. As with the paper bags they would always leak dust and the chamber and motor filter would be dirty. So why on earth would you use paper under that circumstance. these are the Clean Fairy brand and work very well in the kenmore.... At about 1.25 Cdn a bag.

I found the brand veva vacuum bags. They are about$1 a bag. I have Kirby version of their bag and they are just as good of not better. I love them and there better than the Kirby brand which is first I've found.
In UK I imagine Germany or Europe close to you would have bags. A good majority of the American vacuums have European versions of their vacuum cleaner.

I have mixed feelings on the HEPA debate.

kloveland's profile picture
For me personally HEPA filtration is on the bottom of my list. Many people have habits and or issues that are far more health devastating. Such as smoking (more than just cigarettes, including second hand smoke) obesity, making poor food choices (me included), lack of exercise and being reckless with one’s overall health are just a few examples. These are things that I would be more concerned about than just a few dust particles in the air.

My grandfather is 89 years old. Although he isn’t doing too well now because of his Parkinson’s disease. I’m almost certain he grew up in a pre-HEPA environment. Probably without electricity back in 1930s rural Missouri. Did I mention he is 89! Living to be 90 and above is a combination of good genes and making positive choices in my opinion.

MadMan, I also agree with you there is a such a thing as having too sterile of an environment. Thank goodness we don’t live in the wild west of the 1800s or in the Oklahoma dust bowl. HEPA bags would make sense in a home environment with multiple, adults and kids dragging in dirt from outside. For me HEPA doesn’t make sense. I’m single and no longer have pets and no bad dust allergies. My primary concern now is the air ducts in my home. My house was built on a slab with the air ducts routed through the slab. The air ducts are deteriorating letting in dirt from underneath the slab and sometimes water. Getting those ducts filled in and routed in ceiling is on the top of my priority list.

For HEPA to work it would probably have to be all over. Is the outdoors HEPA filtered? Most of our work environments are probably not using HEPA rated vacuums. I do agree that HEPA bags probably do keep vacuum bag chambers cleaner and are probably less restrictive on suction as the bags fills. I haven’t used a HEPA bag long enough to see this for myself. I love using my vintage machines. I primarily use Hoover Convertibles, Hoover or Elux canister or an old dusty Kirby with no ill health effects. But then again, I’m a collector. I know being personally responsible for my own health by trying to eat the right things and exercising frequently will be more beneficial to me than using a HEPA certified vacuum. I’m not necessarily harping on this thread but other threads I’ve seen on vacuumland that discuss HEPA. I think having perspective is good!

Good points there!
I only use hepa bags because they keep the bag compartment clean and airflow/suction doesn't drop like it does with the paper bags.
I have quite many vacuums what originally came with the post motor hepa filter.
When hepa filter in many of my vacuums has become dirty I have replaced it with just a foam or thin micro filter. I really don't need expensive hepa filter.
All I care is to keep my vacuums performing well/clean as possible.
For old vacuums like in the picture hepa bag really keeps it clean and performance doesn't drop so quickly.

mark40511's profile picture
severe allergies either. HEPA bags do keep the machine super clean. I recently got a Cirrus upright vacuum last year. The Genuine HEPA bags aren't expensive and last forever. I wanted to see how long I could go without changing it. It was KILLING me to go so long but I wanted to push it. Finally, after about 4 and 1/2 months of almost daily use, I changed the bag the other day. The bag had no smell because of some activated charcoal granules sucked up in the bag. There literally was not a SPOT of dust in the bag chamber. The bag held all that filth and kept the vacuum clean. I think they make the HEPA filter last much longer too but I'm not 100% on that as I think carbon dust ends up getting to the HEPA before anything.

I'm in my 50's and only "discovered" hi-end closed system vacuums and HEPA filters in the past few years. These past few years are the first time in my life I have nearly no allergy symptoms when most of my life they have been severe. Maybe this change in allergy reduction is due to something other than my vacuum system but I can't think of anything else.


I know for a fact whenever I would vacuum with my old Dyson DC14 I'd be sniveling that evening... which made me vacuum less... which compounded problems over time.

As much as I love HEPA

mark40511's profile picture
bags, I do sometimes wonder if it's the rubber area seal around the collar of the bag and how tight of a fit that goes onto the vacuum that's most important. You can have a HEPA bag or a paper bag and they can both leak if that's not a good seal connecting to the bag. I had this problem with Kenmore canisters. Always always dust in the bag chamber. My Epic 6500, even using the 4 play paper bags, no dust in the chamber...those aren't HEPA bags......but I do notice airflow drops off rather quickly on those. With HEPA bags, the airflow stays pretty decent throughout.......which you would think would be the OPPOSITE since HEPA bags are thicker.

Keeping a super clean home might not be the best for people and their immune systems, but it's better for things like your refrigerator, HVAC, etc.

Hepa

lesinutah's profile picture
I've come to believe that HEPA bags filter really well. I noticed my compact with HEPA gets very fine dust. The vacuum performance is about the same. If you have allergies I'd only use HEPA(I don't have allergies). I still tend to use hepa. Older eureka/hoover/sanitairre f&g I use oem or high filtration. The royal I use type a royal bags they seem to work better than other bags. Type b royal Im not a big fan of I use other HEPA bags.

HEPA Cloth bags are definitely NOT a gimmick. They do work better than paper bags. I find I don't sneeze as much, don't see as much dust on furniture & don't have to vacuum the pre-filter on my Honeywell air purifier as much if I use a HEPA Cloth bag in a vacuum that doesn't have a HEPA exhaust filter, like my Kenmore EVPC canister or Royal Metal & Kirby uprights. In fact, HEPA Cloth bags, even generic ones, work so good that whenever I get asked for a vacuum recommendation for a allergy sufferer, I always say first that if there is a HEPA Cloth bag available for the vacuum to try it first before replacing the vacuum. While it doesn't capture the carbon dust on the exhaust, the HEPA Cloth bags will capture the majority of the fine dust that triggers allergies.

However, unlike some other members here, I have not found them to maintain the vacuum's suction or airflow better than paper micro-filtration bags. The ONLY bag I have found to be the exception to the rule is the Miele AirClean & Miele HyClean 9 layer HEPA Cloth bags - those bags are amazing in that you can stuff them full of dirt till 3/4 full & only then do you see suction & airflow drop off slightly, & no dust in the bag chamber either. Any other vacuum though, like my Kirby or Royal Metal uprights, use the paper micro-filtration bags in them & they maintain airflow just as well.

Kenny & MadMan - I disagree with you guys on the importance of keeping a sterile environment. Yes, a lot of people born years ago didn't have a allergic reaction if you vacuumed with a vacuum with no filtration that let off lots of dust. However, there are LOTS of kids being born these days that are allergic the moment they are born. Furthermore, what we know today is the dust in carpets is not healthy! And that's not just my opinion, that is a proven fact! There's a reason why leading environmental & government agencies say that indoor air quality in today's tightly sealed homes is a problem. Do you guys have ANY IDEA of the chemicals & processes used to manufacture carpeting? I bet you didn't know that FORMALDEHYDE, the same chemical used to preserve human corpses before burial, is used in the carpet manufacturing process, & remains in it & leaches into the indoor air after it is installed. Plus let's not forget the chemicals that leach out of plastics, finishes & painted surfaces. Your average vacuum is using this air to pick up dirt & dust, & then spreading all that dust & chemicals all over the house!

I see nothing wrong with letting kids be kids & letting them go outside & play in the dirt - but they shouldn't be breathing dusty air from a vacuum & being exposed to all those allergens. You should at the very least be using a vacuum with a HEPA Cloth bag, or a sealed HEPA filter on the exhaust, & if it's bagless empty the bin outside. I also think it's a good idea to have a HEPA air purifier running too. Yes, kids should be kids & you can't protect them from everything, but I see nothing wrong with taking a few preventative measures to reduce the chances of them developing allergies later on.

Mylesrom - I would be careful buying those Kenmore bags by Clean Fairy. Just because you don't see dust in the bag chamber does NOT mean they're not releasing dust into the air. Bill, Vaclab on YouTube, just did a test where he compared a Kirby HEPA Cloth charcoal lined bag with the Clean Fairy Kirby HEPA Cloth charcoal lined bag. His tests showed the Clean Fairy brand released a LOT more dust into the air than the genuine Kirby bag did. Sure, the performance of the Clean Fairy bag would have been OK if it had been used in a vacuum with a HEPA filter on the exhaust, but not on a direct air vacuum where the bag is the only filter. I also personally have bought a couple packs of the Clean Fairy Miele FJM bags, & I wasn't impressed with either the quality of the HEPA Cloth material used or the bag collar. I definitely won't be buying from them again.

Mark - Yes, you're right, the seal the bag collar makes with the vacuum when installing the bag is important. A HEPA Cloth bag will do no good if dust & dirt can leak around it inside the vacuum. The Kenmore canisters are a good example of a less than ideal bag collar & bag holder design. The reason why you constantly saw dust buildup in your Kenmore canisters using HEPA Cloth bags was because the bag collar would slide up slightly in the bag holder, & some dust & dirt wouldn't make it into the bag to be captured & filtered. I personally make it a point to tape the bag collar to the bag holder on my Kenmore canisters to decrease the chances of that happening.

The riccar brand HEPA bags for rsl4 doesn't reduce suction, Kirby newest HEPA loses very small amounts. I don't have a Miele and seen there bags they look the most convenient and consumer friendly bags out right now. My compact doesn't lose air flow with HEPA bag. There are a few but it's alot healthier on vacuum with them. Les

We are all different

kloveland's profile picture
with different levels of allergies. I can't make a generalization based on everyone. I don't think anybody can. I was just reading an article on Formaldehyde one of the remedies was to open a window. Which defeats the whole purpose of having a sterilized home in the first place. The article also said the levels of Formaldehyde are highest when products are new. Maybe some of these allergic kids are allergic because their environment is too sterile. I'm a not an allergist. I'm just guessing.

If a person is reasonably healthy the body's immune system should be healthy enough to fight off colds, etc. Go outside for a walk and breathe in some fresh air. lol!

My cirrus upright

mark40511's profile picture
vacuum........I filled that bag up and if there was a loss of suction, it was VERY little. Now, on the Kenmore canister, I noticed a loss of suction as the bag filled. My Kenmore blue canister where the PN died, I use the vacuum as suction only for the garage, and I do TAPE the bag so that it doesn't slide off.....but I still feel like even with that, it doesn't make a tight enough seal like, say, an Electrolux canister. I get better results with the Electrolux paper bags keeping dust out of the bag chamber than I do the Hepa bags in the Kenmore canisters. That bag collar design has GOT TO GO.

KirbyLux77

I never said that the Clean Fairy or other generic hepa type bags were equal to Miele or Kirby original hepa bags...they are not. The question was are they a gimmick and my response was they are better than the paper bags, which they are. The original Kenmore paperbags always leak into the chamber. The Kenmore Progressive doesn't have a perfect seal at the neck connection anyways, so I would not spend 5 or 6 dollars a bag on them and I did have a couple of SVC hepa bags that came with the canister when I purchase it for 10 dollars. They were no better quality than the clean fairy bags. If I had a Kirby or Miele I would only use their original hepa bags... I wouldn't chance a Miele on generic hepa bags.

I watched his videos... Kirby Orignal Paper = 11,559. Clean Fairy hepa type, 1400 at 0.3. So even generic hepa type are better than paper. Though not as good as Original Kirby or Miele bags.

Miele GN bags are fantastic. They are very thick and airflow difference between empty and full bag is very small. Only 10 cfm loss with full bag.

on the point of Clean Fairy hepa bags.....even though the Kirby HEPA bags were much better in his testing, even HE stated that the CF bags were just fine ( he gave numbers to compare by)....the '1400' number for emissions is very small....nothing like paper bags. Just for clarity :-). I bought them and told someone else about them and then he sent Bill/Vaclab to test....and I have noticed no difference from a 'users' perspective compared to the genuine HEPA bags.

I did know about the formaldehyde issue in carpets....I worked in a air quality control for a brief time. SO I use ozone/neg ion generating machines to neutralize the out gassing of a new carpet/drapes/cloth furniture(less than 50ppm). Good points though you gave on that and indoor air quality!

Kelton - First of all, thanks for the compliment. When I found out a few years ago I have allergies, I decided to become educated on indoor air quality so that I could reduce my symptoms. As a result, I am much more careful about cleaning practices, the quality of vacuum I use to clean my home, & I constantly have a Honeywell HEPA air purifier running 24/7 in my living room. I am currently using a 2007 Miele Callisto & a 2014 Simplicity Gusto.6, both with HEPA filters & HEPA Cloth bags, to clean my home, & both are immaculately clean & in pristine condition.

As for the Clean Fairy Kirby HEPA Cloth bags, I would agree with you - the result isn't "that bad". But, compared to the genuine Kirby HEPA Cloth bags, in my opinion they ARE bad....90 particles for the genuine Kirby HEPA Cloth bag vs 1400 particles for the Clean Fairy Kirby HEPA Cloth bag is a pretty big difference! That to me is unacceptable. If it had been under 500 particles for the Clean Fairy Kirby bag, that would be acceptable & make them a good alternative Kirby HEPA Cloth bag. If this bag was being used in a clean air upright with a sealed HEPA filter system, like a Miele Dynamic U1, Kenmore Elite or the Cirrus uprights, you could sacrifice the quality of the bag a little to save money buying generic bags, but when you consider this is the ONLY FILTER in a direct air upright vacuum, that isn't acceptable. And especially when there are plenty of other generic Kirby HEPA Cloth bags on the market by Envirocare, Crucial Vacuum, Zvac & VEVA that are widely available. If it's acceptable to you & Bill, more power to you & you can choose to use what you want. My personal preference though would to be use a better generic brand with better particle emissions, or just buy the genuine Kirby bags & spend slightly more for better air quality. I hope that one day Bill can get his hands on the normal Clean Fairy Kirby HEPA Cloth bags that are not infused with charcoal....I have to wonder if it's the charcoal layer that could partly explain their poor performance compared to the genuine Kirby HEPA Cloth bag. I appreciate your points though & contributing to the conversation here.

Mylesrom - You're right, NOWHERE did I say in my post that you said the quality of the Clean Fairy bags was equal to the genuine Kirby or Miele bags. All that I am saying is, based on Bill's tests of the Clean Fairy Kirby HEPA Cloth bag & my own experience with the Clean Fairy Miele FJM HEPA Cloth bag, I personally don't recommend the brand & will not use them again & I would suggest you try another brand. Based on what Bill experienced in his tests, & my own experience, it is highly likely those Clean Fairy bags are letting a LOT more particle emissions you cannot see than you think, even compared to the SVB HEPA Cloth bags you used previously. Considering your Kenmore canister either has no exhaust filter or has a HEPA filter in a unsealed system that can leak dust around the HEPA filter, that makes the quality of the bag used even more important. Even Kenmore noted in the certifications included with their vacuums that the particle emissions claims they made were based on using the vacuum with BOTH a HEPA Cloth bag & HEPA filter, because they knew their vacuums were unsealed HEPA filter systems. The ONLY VACUUMS they have ever produced that had a sealed HEPA filter system were the Kenmore Elite bagged canisters & uprights, the Crossover bagless uprights & some of their vacuums that were produced for them by Electrolux AB & were rebadged Eureka vacuums. And yes, you are correct about the seal on the bag holder of the Kenmore canister vacuums not having a perfect seal with the bag, but that's the reason you would tape the bag collar to the bag holder, so you maximize the seal the bag collar makes to the bag holder & the HEPA Cloth material has the best chance of capturing the fine dust & doing it's job of filtering the air. By the way, I have actually used the SVB brand Kenmore HEPA Cloth bags your vacuum came with, & actually found them to be pretty good for a generic bag. That is one generic brand I do recommend.

As for your statement that you would only use a Miele with their genuine bags & wouldn't chance using generic bags, I have used the generic bags with very few problems. They don't leak lots of particle emissions & cause problems with the motor like some people here claim they do. Plus, even though their filtration is obviously not as good as the genuine Miele bags, that is irrelevant since the Miele canisters are a sealed HEPA filter system vacuum. As long as the bag isn't leaking lots of dust into the bag chamber, it's perfectly fine to use generic bags because the HEPA filter on the exhaust will capture any particle emissions that escape the bag.

My experience with the generic bags has been the problems are mostly with the bag collar itself & it's design & quality, not with the quality of the bag material itself. If you read Amazon reviews on the generic bags, you can also draw the same conclusion. The generic bags that have the AirClean style collar used the first version of that collar that Miele only used the first couple years the bag has been made. The problem Miele had with the first version of the AirClean collar, & why it was changed, was that the bag installed properly in the holder & worked fine when first installed, BUT if you open the bag door to check on the bag, the bag collar becomes unclipped from the bag holder & slides up slightly in the bag holder. The consumer then closes the bag door without noticing this, the bag door tube doesn't penetrate the bag collar fully, & some of the dust & dirt goes around the collar & into the bag chamber. Even a fellow Vacuumland member who is a Miele dealer, Piano_God, noted in one of his posts that this was a issue with the first generation Miele AirClean / Miele HyClean bags & to be sure to push the bag back fully into the bag collar & make sure it clicks into place before closing the bag door. Since the generic bags up until recently used this first generation AirClean style bag collar, that is why consumers were seeing problems with dust leakage & didn't realize if they were more careful to make sure the bag was installed correctly before closing the bag door, they would have had no issues with dirt & dust escaping & the bag would work just fine for them. However, this problem is slowly starting to go away, since there are some brands of generic bags using the AirClean style collar that DO NOT unclip from the bag holder when you open the bag door, thereby lessening the chance of consumer error. I have also seen personally on some generic bags with the AirClean style collar that the silicone seal can detach from the collar, however you can always just change the bag if the seal does detach & it seems the quality of the silicone & the method in which it is attached to the bag collar has improved over the years, the recent generic bags I have ordered have not had this issue. The only other issue the generic bags have is they do not allow the vacuum to maintain airflow as well as the genuine Miele AirClean / Miele HyClean bag - the walls of the bag clog with fine dust & dirt & restrict airflow. However, that problem is easily solved if you take the bag out after each vacuuming session, take it outside, give it a good vigorous shake, & then reinstall into the vacuum. Doing that loosens the dust & dirt from the walls of the bag & restores airflow.

As long as you only buy generic bags that have the AirClean or IntensiveClean style collar & you make sure the bag is fully inserted into the bag holder & clipped into place, you will have no problem with bag leakage. I would strongly suggest avoiding bags with cardboard collars though - the collar can bend & warp, & not allow the bag door tube to insert fully into the bag collar, which can cause dirt & dust leakage. Even Tom Gasko, Dysonman1, has said he uses generic bags in his Miele canisters, in particular the 3M Filtrete bags with the IntensiveClean style collar, & he finds they work just fine & don't leak dust. Take a look at the bag chamber of my Miele Callisto....do you see any dust leakage from this generic bag?

Kenny - I totally agree with you. I don't think you can make a generalization that everyone's allergies are the same. There are people who's allergies are mild, & those that their allergies are severe. My only point is, as I said in my post, is it seems more kids these days are being born with allergies right from the moment they are born. And of course, we have no idea of what causes a child to develop allergies to certain chemicals, foods, grasses & other things in their environment. My whole philosophy when it comes to my health is that saying "A ounce of prevention is worth a pound of cure", meaning that if I can prevent sickness, disease or illness from happening in the first place by taking the best care of my body, eating right & exercising & taking the right supplements, I do it. So, since we all know indoor air quality is a concern due to dust & dirt in carpeting & various chemicals in the air from the products we use in our homes, I wouldn't want my kids if I had any exposed to dusty, dirty air from a vacuum & I would want a air purifier running at least in the family / living room of the home. I think it would be a good idea to take the preventative measure of using a vacuum with HEPA Cloth bags, a sealed HEPA filter system, or both, & if I was using a bagless vacuum to empty it outside. Having said that, I don't want my kids exposed to a "sterile" environment - I think it would be healthy for them to be exposed to allergens outdoors while playing & let them be exposed to "healthy allergens" in fresh, clean air, not toxic ones inside your home. Kids will be kids - let them go outside, get dirty, exposed to dirt, dust & allergens, let them get healthy exercise in, let them be exposed to allergens that way. I would just rather practice caution in the home in case they do develop allergies to some of the toxic chemicals in the air in our homes.

It appears that many people forget

vaclab's profile picture
when discussing particle emissions is their own indoor air quality.

Example: Person "A" demands a fully sealed H13 level system and their typical baseline air quality is 100,000 0.3um. Won't really have any appreciable effect, right?

Example: Person "B" has an average home 0.3um of 1,000 or less, then I'd say nothing less than full H11 would be appropriate.

In my home, using "el cheapo" $2.50 MERV 7 HVAC filters, I usually sit around 10,000 0.3um; however, when my HVAC runs continually (peak hot/cold weather), I can see a home average as low as 4,000 0.3um.

Clean Fairy bags may be just fine for the average home and I'd bet most people wouldn't notice the difference.

As for the charcoal CF having some appreciable negative effect, I would venture to guess that since the Kirby charcoal HEPA and black HEPA bags both tested great (both under 100), the CF non-charcoal bag would also be similar.

Hope this puts things into perspective,

Bill

I'm glad Bill brought this up . . .

I was just about to point out exactly what Bill mentioned. All of this speculating on the possible inferiority of "generic" bags means nothing unless you know the baseline particle measurement for your home. If you haven't measured it, then you're just guessing.

For the record, I'm the guy who sent Bill those Clean Fairy charcoal bags after Kelton sent me a link on Amazon. They look exactly the same, so I thought there could be a chance they were made in the same Chinese factory, which would make the Clean Fairy bag a real bargain. As Bill discovered, they look the same, but the Clean Fairy bag has fewer cloth layers, so this probably explains the higher particle reading (and lower cost). Bill and I spoke about this at length and the takeaway was that the Clean Fairy bag is probably more than good enough unless you need to live in a highly filtered environment AND you have real measurements that confirm you have achieved this with your baseline air quality.

Anecdotally, I've been using the Clean Fairy charcoal bag for a few weeks now and I can't seem to tell any difference. I do not suffer from allergies, so I'm not as sensitive to this issue. However, I have a dog and I find the smell from non-charcoal bags to be disgusting. Even the Simplicity HEPA bags I bought from Tom at the (former) Tacony museum for my Ultra Premium started to smell after just a couple of uses. I have yet to find a non-charcoal bag, regardless of filtration, that doesn't smell awful after a few uses. So, as a pet owner, I'm on the charcoal bandwagon all the way. I haven't tried using granulated charcoal in a non-charcoal HEPA bag yet to determine if it offers better or worse "odor" performance. But, that is more of a hassle than just buying charcoal-infused bags. I suppose this could be yet another performance factor Bill could measure. Does someone make a "smell-o-meter" that could provide some insight?

Both the Kirby and Clean Fairy charcoal bags seem to offer similar performance. Maybe the Kirby bag won't smell quite as bad once it gets full. Maybe not. Until then, they seem to work just fine.

Adding charcoal

mark40511's profile picture
granules to a non-charcoal HEPA bag definitely works! This is what I do in my Cirrus upright and I was able to go 5 months without changing the bag. Had it not been for the charcoal, NO way would I have been able to go that long. A long time ago, I bought a big container of fish aquarium charcoal and I've hardly put a dent in the big container. But I don't think charcoal bags exist for the Cirrus upright?

Charcoal is Overkill in my opinion.
Veva makes a better HEPA bag than Kirby. The hepa bags for TriStar isn't brand name.
People like charcoal bags it's a personal preference.
Everyone is entitled to opinion and preference for things. Some people are blinded by own convictions and proving their points. The person is so focused on proving point and being right they are oblivious to doing do changes how people perceive them.
If people are entitled to opinions they're also entitled to false beliefs.
Continually posting how correct you are you lose respect. Nobody is going to read 7 posts with half hour worth of videos. Nobody cares to listen to how someone is right.
It shows they are self absorbed and extremely insecure.
The continuance is not needed. It's sad to see going to the extreme it seems there Almost mad.
I wish people well but delusional self absorbed selfish people only concern about themselves and their correctness really need to step back and enjoy life get over insecurities and live.

Hey Les, I do believe in the Kirby Charcoal Odor control bags. Our Golden fur in our old Hoover Platinum is what led me to this site and eventually to a Kirby with Charcoal bags. Before with our Hoover I literally needed to open windows when we’d vacuum. We brushed our dog regularly and she didn’t really stink up our home. Now with the charcoal bags I can go about a month on a bag before I’m smelling dog. Like you say though, to each their own. Do what you like and what works for you.

I just had a thought. I read your post where you said you got a month on a bag before smelling dog? I'm assuming that's when u change the bag? If not, I wonder if you would try to suck up a tablespoon or so of charcoal granules and I'll bet a day later your bag will smell new again? What happens with my upright is after a couple of weeks.....I will start smelling a slight stale smell, I suck up a little charcoal, that lasts 2 to 3 weeks or more before I started slightly smelling anything, I suck up a little more......rinse repeat. It's like the next day after the charcoal has been sucked up, zero smell. I think the dirt eventually covers it up.

I have used granulated activated carbon in my vacuum bags, & it does work. But, you must wait until the bag starts to smell, & THEN put a couple of tablespoons of carbon on a flat surface & use the hose to pick it up. If you put the carbon in the bag when it is new before installing in the vacuum, all that happens is the carbon gets buried by the dirt. If the vacuum sucks up the carbon, then it goes directly to the dirt & to the walls of the bag, which is where the odor is - NOT just getting buried under the dirt where it has no odor reducing effect.

One other way to put a charcoal filter in a vacuum is to make a pre-filter. I have a Honeywell HEPA air purifier in my living room, so since it uses a charcoal pre-filter wrap, I bought a extra one & take the material & cut a piece of it to put in the vacuum's pre-filter holder in the bag chamber. Just make sure the charcoal filter is at the bottom & closest facing to the motor, with the vacuum's normal pre-filter on top of it for it to work effectively. If you go with this method instead of using granulated activated carbon, the filter needs to be replaced every 3 - 4 months, depending how bad the odors are & how quick the charcoal wears out.

I've read all your pros & cons, and decided to try to be a little more open-minded regarding the benefits of Hepa bags.

I've ordered some cloth-type Hepa bags, and charcoal-infused bags too.

Was Kirby's term "Micron Magic" their name for Hepa?
Has anyone tested airflow? Paper v Hepa.
Comparisons between the two?
Does Hepa leave larger particles behind in your carpets?
Anyone vacuumed with Hepa THEN again with a conventional paper bag to see whether much (if anything) was missed?

That'll be the first thing I'll do. Someone must have done this already.

Hepa bags typically increase the machine's airflow. Here are a few tested examples I also had a more extreme example with a Vita-vac (rebadged airway) where paper bags got a baird 4/10 and the hepas 6/10 if i recall correctly meaning about a 16 cfm difference. I think the surface area effects the increase, the larger the bag is the less of a difference it makes.
They typically increase airflow, and retain it better as the machine fills. With bypass machines there is also the benefit of less dust getting into your components.

Now this doesn't mean they're a must for everyone. I don't really have allergies but I always use hepa bags if I can cause they keep my machine cleaner and performing better.

As for testing using a pickup method, following behind a machine isn't really a good way to to gauge performance. Any vacuum following another one will typically find more dirt which gives the impression that the one after it is superior. I've tried this using a TOL Simplicity S40 and then following it up with a Simplicity Pixie stick vac, it found more pink sand after it, it doesn't mean it cleans better. A better way to do it would be to put an equal amount of dirt into an area and see how much of it is removed.

I like your idea of those tests.... I don't recall reading any tests of the MicronMagic semi hepa/paper bags vs the cloth HEPA rated bags. You know the cloth ones HAVE to be better but it was a later design and the industry moved to the cloth ones ie rendering the earlier versions largely, obsolete (except for Collectors' of course).

Here's a good alternative, Vacuum America Clean Vac 7 Perfect P103, P104, P107, P108 / Royal Style B Uprights H-10 Hepa Filtration 9 bags for 17.99. I've been happy with the brand so far. I actually had a Royal L bag in my unit during the test. Mostly because the shop never sold a single pack of them in my time there. Figured I'd use them to get rid of them

Particle Tests With Five Kirby Bags




Kirby MicroAllergen Plus HEPA Bag Particle Test




Clean Fairy Charcoal Kirby Compatible Bag Particle Test




Before I was on YouTube, I did some fairly extensive airflow loss testing primarily concentrating on HEPA bags for Kirby, Electrolux (Perfect) and Hoover (Crucial). When they were filled they did lose some CFM but the loss was minimal.

Here are some percentages all measured at the body of the machine (not power nozzle as I hadn't built my first airflow box yet).

75% Full Kirby HEPA bag lost about 10.7%
100% Full Hoover HEPA bag lost about 13.4%
100% Full Lux HEPA bag lost about 14.3%

Hope this helps,

Miele FJM HEPA Cloth Charcoal bags

kirbylux77's profile picture
Since there has been talk in this thread about the Kirby charcoal bags, I found these generic Miele FJM HEPA Cloth charcoal bags online. For those that don't want to use a generic Miele HEPA filter with the charcoal layer, don't want to use the Active AirClean filter with charcoal, or put activated carbon into bags or use charcoal sheets, these bags are a interesting option.

bigger things to worry about ...

vap0rtranz's profile picture
There's bigger things to worry about than vacuuming with HEPA.

Combustion stuff in the house is a big thing. Wonder why gas furnances & water heaters are required by most codes to vent outdoors now? CO and other nasty stuff used to just waft around as fumes in our homes! I remember growing up and my Dad working on the oil furnance -- there was no ventilation to the outdoors, it just vented in the basement. LOL.

There's loopholes in these codes for homes. Anyone cooking on gas / propane stoves should be venting _outdoors_, but I lived in an apartment built in 2000 that had a range hood that just recirculated the air. Hah! More combusted fumes to breath in.

A friend made me think twice about radon because he was buying a townhome with a basement. Radon causes cancer, my friend told me, and so I poked around on that. You can get a home test kit to check for it, but I've bought homes with basements where the seller refused to test for radon because they knew it would fail. Fixing radon is expensive.

Mold from wet basements / crawlspaces is another problem that I've fixed. Mold is pretty cheap to clean up but is also expensive in the long run. The includes a dehumidifier that's constantly running so the electric bill goes $$$!

So there's bigger things to fix in our homes -- like things that can literally KILL -- and folks think the air in the home is safe so they move on to fixing dust & pollen, but there's plenty of loopholes in building codes about indoor air quality. Dust & pollen don't kill most folks, unless you have a severe histamine reaction and I do not. So I'm focused on that big stuff.

I tried converting my Kirby 561 to paper/HEPA but the effort was too much and now I vacuum with cloth. I do use high MERV filters in my HVAC (>12) and that is to help reduce dust & pollen in our home. If you compare how often we vacuum to how often HVAC systems run -- that's 1 / week for me versus every 10 - 20mins for the heat/AC -- the frequency of HVAC's impact on indoor air quality is still much bigger than a vaccum.

A VENTED, top fill central vacuum cleaner with a flow through motor.  Just saying.

 

You can use any type bag you want, it won't matter because all the exhaust goes outside.  

 

Even if you live in an apartment and need to make a temporary vent through a window when using it, your health is worth it.

As much as I prefer to vent a central vacuum outdoors, however in my humble opinion I feel like it is better to have a central vac equipped with a ActiVac III HEPA exhaust muffler. Not only you won't pollute the air outdoors but also you won't have neighbors to hear the noise of your central vac while running and you won't have bugs or insects to crawl the inside of your exhaust piping. There was a moment or two when I wondered why there were dead wasps or yellow jackets inside the motor compartment of our Eureka central vac which is vented outdoors, didn't took long to figure out that there was a wasp nest built right up where the end of exhaust is coming out at. And that's definitely a fire hazard if you blocked or clogged the exhaust piping of your central vac.

Also regarding central vacs with thru-flow motors in it. I would highly recommend to use only genuine bags, not generic. And/or I would highly recommend to use cloth bags, not paper. Otherwise without multiple layers of filtration, you would most likely to have bearing noises. That's one of the reasons why I'm leaning towards on getting the MD Modern Day M715h for myself that uses a bypass motor over the MD Flo-Master F650t that uses a thru-flow motor.

I have a new, old stock MD Flow master I got 3 months ago.  It has a flow-thru motor.  In addition to using generic single port bags, it has about 3 inches of that woven foam at the bottom of the dust container to keep anything from getting into the motor.

 

I prefer flow-thru because you can vent  ALL air coming out of the CV and that includes the heat, carbon dust, and noise coming off the motor itself.  

With a by-pass motor, the only thing you're venting is the vacuum exhaust.  The motor heat, carbon dust, and noise stays in the house.

I wouldn't worry about finding a dead bug in the motor compartment or exhaust piping.  Obviously, if you'r using your vacuum weekly, they won't survive and will get blown out the line.  You can also get a self closing exhaust cover if that's really a big problem.

 

A flow-thru is quieter and you get more suction out of it compared to a by-pass.  A flow-thru motor is cheap to replace when the time comes.  I saw a new one just the other day for $39 on Ebay incl S/H.

 

This is my current temporary install. All I needed was a vent hole and a plug in my utility area.

subject of this thread

Hepa bags are nice, they are better than paper, though more expensive and they are not environmentally friendly.  They are after all woven plastic whereas a paper bag is paper and will easily break down in the ground.

 

In a Central vac. that's vented, a simple paper bag is all that's needed.

I have to second with Alex on this one... I have a few central vacs 2 of which are MD one is an Airmaster A-650 which has a flow-thru and the other being the Modern Day M715H the rest are either true cyclonic or filtered cyclonic. The power on the 650 is pretty good and I was very happy with it but there were a few things that I was not happy with. The M715h is more powerful being an 8.4" bypass motor. Although looking at the specs it has 7" more in water lift and 6 more CFM than the Airmaster and given the designs and differences there are a quite a few things that separate them. When it comes down to the Flow-Thru design and this comes from a technicians (me) point of view machines that are used with HEPA bags actually will last longer than those used with paper bags. Reason for saying that is because HEPA bags actually don't clog as fast as the paper and there is less debris getting through the HEPA material keeping the motor clean unlike the paper bags. The paper Bags are subject to bursting which I have had a few burst before, and they tend to actually choke off airflow after a certain period of time as to where the HEPA can maintain that airflow to allow for maximum capacity. Those pre motor filters in the MD machines are the consistency of buffing pads used on commercial floor buffers and could probably be used as one too so it most likely will stop the Large debris from entering the motor but will not stop the other fine material from doing so which could cause and is the leading cause of damage to armatures, brushes and bearings. Another thing is that the Flow-thru motors rely on good airflow to keep the motor cool as to where the bypass machines actually have a cooling fan on the top of the motor so regardless of whether or not there is a clog the motor will not overheat as to where the Flow-Thru will overheat and that could potentially cause damage and or be a fire hazard considering flow-thru motors tend to run hotter. Fire hazard being whether or not the thermal protection kicks in and I have seen a few Flow-Thru motors that have had that happen. Yes the Flow-thru motors are very quiet and would be my ideal choice if I were installing in a utility closet but the Modern Day machines are pretty quiet as well due to the rather large lifetime filter placed over the motor and are ideal for cellar/basement installs which is where mine is located. All in all I would recommend you follow the manufacturer's recommendations but it is your machine and your wallet so do as you please but when it does need a motor, don't buy some chineseium motor based on its price, especially if you want the same or more performance. There is a reason MD used the materials they used when they built the machine.

There are some bypass units like Cyclovac where not only they use suppressors to help keep the noise down but they can also catch some carbon dust that would leak out of the brushes, they also use a carbon filter to catch whatever else it would collect. I don't see heat being a huge issue with bypass motors, especially since they're designed to help cool the motor down. And there are some bypass motors like the MD SilentMaster S900r/r2 (Dual Motor) where all of the exhaust exits out of the motor completely, also more powerful and just as quiet as my uncle's MD Flo-Master F650t. I don't believe all thru-flow motors are quieter than bypass motors. But yes they are inexpensive to replace.

The Eureka is the unit we have over in our storage shed, it doesn't get used much. If someone used that vacuum while the exhaust is blocked, they would for sure stress the motor and possibly melt some of the piping. I could put a vent cap in if I wanted to but I have found that they can break overtime so it wouldn't really make much sense for me to put one in if we're not going to use it very much.

And there are few companies like Sebo that sells cloth bags using some recycle material, I also don't see how that is not environmental friendly.

Each to their own of course.

 

A cloth bag is going to need cleaning and emptying which is a mess.

 

Paper bags just pull out carefully and install a new one, then throw the full bag.  Takes 2 minutes with no messy dust floating everywhere and no cleaning anything.

 

With single port paper bags being only $2-3 each, a typical user could change out every 3 months at a cost of only $1 a month.  

 

Not letting it fill all the way up leaves the exposed paper to act as a fine filter and retain suction.

 

I can only imagine the cost of those  MD 3 port hepa bags. Hepa bags are woven plastic and strong material.  They don't decompose easily.  I'd feel guilty using them.

Microfibre bags are brilliant.

Of course, as someone mentioned, paper is better for the planet, but personally I don't really trust paper bags because of how weak they can be and how dust can easily block the suction. It's sad though because I actually personally care about the dying planet and it would be nice if paper bags could actually mechanically work. You can use them but sadly they don't help the motor. Tell me if I'm wrong because I'm not a total expert.

I don't know if HEPA bag is a different term or anything, but if it's the same as a microfibre bag then fair enough :) But I've figured out, on one of my vacuums, the Gtech Pro 2, when you take the bag out to take a look, the only thing you have to be wary of is dirt coming back out because you're taking some of the suction path with it (hope you get what I'm saying). So I block it off with my hand and therefore it goes onto me rather than into the air.

For a Hoover Purepower you can get a set of '4 your home' microfibre bags that cost £6, compare that to a genuine H20 paper bag that costs up to £7/8 depending on order choice (both are prices on Amazon UK). Strange really to say that you'd expect higher qualities to cost more, but it'll be more likely due to the fact that the '4 your home' bags aren't genuine but work anyway.

Wow a lot of posts here

Let’s also note that a self sealing bag, appear or hepa...is no doubt far better than a cloth shake out bag or a bagless dyson or any bagless where the dirt needs to be dumped. Dumping any time of cloth bag or bin creates a toxic dust cloud and wearing a dust mask isn’t eliminating the dangers as it often settles on your clothes and exposed skin immediately.

The idea of a vacuum is to capture the dirt and dust so anything that does this the best clearly is doing a better job at it than another. Some people are more sensitive to certain pollutants in the air than others so for someone that finds better relief from vacuuming with hepa bags versus non hepa clearly then it’s worth the expense for them. Others just want the cleaners fair possible from a vacuum and others who don’t have issues with the allergens may not want to spend for hepa bags.

But having been a user of many vacuums and Aerus/Electrolux canisters for most of my life. I can say that a combination of factors really makes a difference...how well the bag seals in the machine, how well the bag seals when removing it to change it, the vacuum’s design snd seals it has itself and so on. A dirty fan vac will push dirty air through it before it gets to the bag, if that portion that pushes air through it is not sealed well enough dirt and contaminants will escape regardless of the bag type used.

A vac that has the motor after the bag is clearly a better design than a pre bag fan as far as leaking goes provided the area where the hose or dirt inlet seal seals well and doesn’t let dirt accumulate around it that could spill into the bag compartment. I’ve seen so many of those Kenmore Panasonic canisters with really dirty bag compartments. Poor paper bags and poor design where the bag and hose and bag compartment door all come together allowing dirt to get into the bag compartment.

I think it seems to be clear that the hepa bags work well based on dirt left behind in the bag compartment and next would be multi layer paper bags and that depends on the quality of the filter paper itself.

The Kenmore vacuums work MUCH better with the aftermarket HEPA bags-big improvement over the old paper bags that have to be replaced when only half filled.With HEPA you can PACK that bag full!On fan first vacuums you need to make sure the bag is properly installed in the machine.Even with my NSSM1 vacuums no issues of leaking dust.Same with any other direct air vacuums I have.For central vacuum fans-I use HEPA DVC arftermarket bags in mine.They come in packs marked for NuTone central vacuums.These bags can hold several gallons of dirt.Will need to see if they can fit my NSS M1'sThe NSS paper bags work well-they can hold 6 gallons of dirt.Come in packs of 6 for about $40 per pack.Have several packs on order.Use the M1 along with my central vacuums.And the NSS is a true portable version of a central vacuum-motor is 13A.

good points Jon

vap0rtranz's profile picture
You make several good points.

Everytime I read about HEPA (and MERV for HVAC), all the experts say:

leak, leaks, leaky

Doesn't matter what bag / cannister is used if the machine leaks.

Your description of the Kenmore reminds me of my Grandpa's old canister vac. We could never get the paper blags flush when inserting, the can was always dusty, so upgrading to a HEPA would make little difference for that machine.

Does anybody do leak tests on vacs?

I've only ever seen airflow / CFM and dirt dump comparisons. I'd assume a rather technical (aka. $$$) system would be needed to detect leaky vacs.

Another good point you make is the mess I make cleaning my cloth bags. Washing them isn't the issue but its the shake-outs inbetween washes. I shake out outside, aiming to be upwind, next to a tree to beat, but you won't be surprised to hear that dust sometimes blows right back at me. So I vacuumed only to have dust thrown back at me. Hah! Defeats the purpose.

Finally, the big reason I avoid HEPA: call me a hippie. Mother Earth is the reason. Like Greg said, HEPA bags are going to take ages to biodegrade. I've a similar issue with HVAC filters: the washable filters don't help with allergens, dog dander, etc. (low MERV ratings). I just discovered that K&N came out with a MERV 11 washable HVAC filter but every forced air ductwork that I've seen takes 4 or 5" thick filters, so I'd have to retrofit -- in a way that doesn't make the HVAC leakier, to bring this full circle and back to leaks. It would be nice if something washable or biodegradable would work for vacs.

I hate to admit that what Dyson popularized & got into many, many homes has the potential to get homeowners HEPA w/out lots of trash. But washing their vacs was a total pain IMO. Plus their plastic fell apart on me so the entire vacuum was trash after 5 years.

Leak Tests On Vacuums

Some things to consider...

Do Cheap Vacuums Spew?




Five Years Old Equals Must Throw Out? | 2015 Bagless Hoovers Closed Room Particle Tests




Closed Room Air Cleaner Test Using A Kirby Sentria II




Closed Room Air Cleaner Test Using A Dyson DC65




As far as paper being "greener", the tree huggers wouldn't agree. Paper bags kill trees and are thrown out at a higher rate due to performance drops and bag splits.

A HEPA bag with a large hole (i.e. Kirby, Royal, etc.) can be reused a number of times without failure.

Long Term Reusable Kirby HEPA Bag Test




What type of vacuum cleans the air more quickly?
Answer: a traditional dirty fan machine using a HEPA (H11 or better) bag. Why? Because they process much more air than clean air machines do. I've measured Kirby and Sanitaire exhausts hitting around 180 CFM right before the bag and more than 150 CFM at the floor nozzle.

Not surprised with the Hoover Air, I have one and have never had issue with the dust and I'm sensitive.

I found Nautavac HEPA bags at Meijer & their bags aren't as good as VAC (Vac America Clean) for my Electrolux 2100 & Eureka Dial-A-Nap ESP

However I tried the VAC HEPA bags for Compact/TriStar & I haven't had to clean out the cloth bag or pre-motor filter as often like I did when using micro-lined paper bags

For me it's the fact that HEPA bags lose airflow slower than paper bags. Disposable bags of either kind win out over shake-out because when you swap 'em, you get (nearly) all your lost airflow back - laundering shakeout bags when they get too dusty is a pain in the rear end.

The superior filtration is a beneficial side effect, IMHO, but if you need it, it's well worth the trouble.

I agree with you.

I can't believe anybody would want to put a mucky cloth vacuum bag in their washer with all that ..... on it.

It's not like washing clothing or bedding that has more oils and small bit of muck.

A vac bag is literally covered in muck. I doubt it all rinses away.

Disposible is def. the way to go, imo, regardless of paper or Hepa.
