Over the years I've worked different places that have particle counters and I personally know which vacuums contain dust and which do not.I wish to share this knowledge. Right now I have access to an IQ air particle tester down to .03 microns.
Please let me know if there are any vacuums you'd like me to test. I have access to a lot of different machines that come in my shop but I'm definitely not going to have access to something rare. I'll try to post a video with the results. |

The first video with the s30 tested has the bag cover off and the particle counter held directly up to the filter. This doesn't address the fact that air around that leaks out next to the filter. Also the motor cooling filter dumps air in that section as well with the cover on.
As I said earlier the S40 at the filter will blow 0 in the particle counter but if you put the particle counter next to it or around other parts of the machine where air leaks out it will Spike the particle counter. The bad quality and filter quality of these machines is excellent right now. Definitely do a decent job filtering when air moves through them. But ds40 still leaks out dust from various crevices. Full bypass vacuums with sealed HEPA post motor filters are really the only things that are going to blow a zero. Tandem air machines as I stated are not designed to filter super fine particulate the HEPA filtration was an afterthought. This is why Tacony as had to make so many different versions of their full size tandem air filters. |

Thanks, vacuumdevil. Apparently, running quietly was also not their mission. |

I used to own a Particle counter (tester), but found it to be another gimmick, like the water lift gauge. It's very misleading to people, and like religion, can be used to justify anything you want. I'm not a rip-off vacuum slinger, and don't sell unrealistic expectations to folks. I sent it back to IQ Air for a refund.

@dysonman1
I definitely have seen them used in misleading ways over the years like anything else. One shot by worked at that used to give a ticket to every repair with the particle counter reading. Never really appreciated that idea. The IQ air particle tester is on loan from the owner of the store I work at. It's actually not my first choice in brand of particle counter and I am currently trying to crowdfund one for the channel. But my goal is not to sell vacuums. I'm simply sharing my findings as a vacuum technician that I have found over the years. As I will not be working in a vacuum shop forever I'd like to preserve this knowledge. |

I too have had one in the past and find I can get any result I want from different machines. One of the biggest issues with a particle meter is that any result that shows zero is BS, Outside of a Cleanroom they can never measure zero. I have used one in a cleanroom before and even then just on its own it will measure a few particles especially if some one has just moved.
Just out of interest, Dysons are designed in Malmsbury in the UK Not Chigago. They might have a few Engineers in Chicago but machine development and design are done in the UK. They have a massive R&D centre in Malmsbury employing several thousand staff. If you go into their video's of how they test their vacuums you will see USA and Euro spec vacs been tested at the same facility. CLICK HERE TO GO TO gsheen's LINK |

FYI all IQAir machines have particle size detection ratings that are in the 0.3 um, not .03 um range as you've previously stated. If I ever come across a reasonably priced handheld PM that can reliably test down to something like 0.01 um, I will consider picking one up.
