I just got thinking, what do you guys prefer ?
HEPA (High Efficiency Particle Arrest) bags, or standard paper bags ? I personally see no problem with paper bags. I've used them with every Vacuum Cleaner I've had and NEVER had one burst. OK, the filtration maybe isn't the best, but most 1990+ Vacuum Cleaners have two or more Pre-Motor filters and a thick Exhaust filter anyway, so practically nothing could get through the motor and into the air. The air flow is another thing, those HEPA bags seem to limit the air flow in my opinion. I'm happy to hear what you think though, so, discuss! :) |

Synthetic for sure. I have seen too many broken paper bags over the years, and bags where the gluing failed. The first synthetic bag which I was aware of were those for the Electrolux Airstream. They cost a small fortune then. |

Polypropelene and other plastics can be made in "soft" forms as well as stiff and hard.For bags-as I go the Synthetic-filtrete bags-I find tthey INCREASE airflow over the paper ones.And you can pack more dirt in them. |

Jm...
I'm going to share my experience here with you regarding HEPA and the HEAP of rubbish Hoover UK used to do when it came to HEPA filters because at one time I was a big Hoover UK fan of a lot of their products until I smelt a rat! As you know by the time the TP3 ended production, HEPA filters were only just beginning to become optional across their cylinder vacuums and Purepower uprights. As a fan of the early Arrianne models and Telios canisters/cylinders, I found that Hoover to be less than truthful about their HEPA cartridges. The slide in HEPA cartridge that took place of the black carbon motor filter inside the vacuum by the bag cut the suction on both the brown Hoover dust bag and the Pure Filt bags, although Hoover UK were forced to admit later, that Pure Filt bags only worked with the higher 1700 watt vacuums and not their earlier 1400 watt vacuums. I know from experience here as my Telios models did suffer from a lack of apparent power because the HEPA cartridge behind the bag cut the suction - and that was with a brand new bag fitted! So, against other brands like Electrolux who located their HEPA filters above the main exhaust, Hoover's 1990's canisters vacuums who had the HEPA filter directly behind the motor suffered from poor suction - this was rectified in the Sensory range where the filters covers over the main exhaust at the top. Now, current vacuums with HEPA bags do not cut suction off, but rather the synthetic dust bags avoid bursting - something that Miele had to do when buyers were sourcing the cheaper brown dust bags for their 1800 watt canister vacuums and then finding that they were bursting because of the force of the suction compared to those that the brown bags were specifically made for, i.e. 1200 watts and lower. HEPA bags are designed to retain bacteria more than basic filtration dust bags - but even today, Vax round tub vacuums that come with HEPA as standard still suffer from bursting dust bags because Vax haven't made the change to synthetics yet - or you use the shake out fabric dust bag to compensate. Hoover's own Purepower uses a higher filter dust bag to compensate from the force of the 2000 and 2100 watt motors in their current PP uprights. |

When I bought my Henry I read about the paper bags bursting and not operating as well as the HEPA-Flo bags, but once I got it and used it with paper bags, I now know that is utter rubbish.
The paper bags don't burst even on Hi power, and they retain good suction throughout their life. That wasn't a dig at you Chris, and maybe you are right, but the paper bags are good too, and for a cheapskate like me, I'll stick with them, ha ha! |

When using synthetic bags, the only thing I think that is left for the after filter to catch is carbon dust. I think little/if any dirt escapes them. Huge difference in the amount of leakage in the bag chamber when using paper vs synthetic. The bag chamber was clean as day when I used synthetic......I can't say the same for paper. There was always fine dust on in the bag chamber area. I think if your machine does have a hepa filter or after filter, it will last much much longer if you use the synthetic bags. Paper bags clog more quickly in my opinion too. I think after I get finished with the 100 paper bags I have for my epic 6500, I'm going to try the perfect synthetic bags. Not sure how long it will take me to go through these. They seem to clog pretty quickly. I change them once every week to two weeks.

I had forgotten about the Vax upright using a synthetic bag. That was all because water could penetrate the bag area and ruin a paper bag. |
