Dysons filtration? Original Message Feb 10, 2010 12:46 pm
How sealed are Dysons? And how good is their filtration? I know the uprights - at least the older, older ones like the DC07 and such might have potential problems with sealing, such as show in this video right here: http://www.youtube.com/watch?v=mXA0N0V2uOQ However there could simply be something wrong w/ that one, who knows. BUT ANYWAYS, are the NEWER uprights COMPLETELY sealed? What about their canisters, such as the DC22, 23? Like does any air blow out of the cord reel or such, or ONLY out of the exhaust where it's SUPPOSED to come out from?

As I understand these are the facts and circumstances that brought down dyson's mantra: Never clogs, never loses suction.
A 2006/07 ruling by the ASA [Advertising Standards Agency].
About 3 dozen disgruntled dyson buyers/users, maybe more, joined by 2 vacuum companies filed a class action grievance against dyson.
The crux of their grievance was that dyson vacuum filters clogged and the vacuums lost suction, contrary to dyson's printed claims to the contrary.
The ASA, a European adjudication body for consumers and manufacturers/their products, agreed with dyson buyers and users and the vacuum companies.
In its decision to Sir James and dyson, the ASA advised dyson under penalty of legal actions for non-comformance, to cease and desist from using the mantra in written format.
Sir James and dyson complied.
The dyson claims went away.
In addition, dyson reduced the time periods for required filter maintenance from 6-9 months to 2-3 months on future models.
Dyson also made its 5 year limited warranty contingent on users following the new filter service/maintenance instructions.

How much are particle meters anyway? The thing is despite a particle meter being used, you'd have to do it in controlled areas that aren't polluted and even Miele's fan man on You Tube's particle meter picks up a lot of dust in his shop at times before his meter bit is put at the vent of the active/HEPA filter exhausts on the Miele.
Particle counters vary much in range from $1,600-$5,000 You don't need a controlled area to get a good idea if a system leaks or not as the meter will give a reading and if that reading rises you know there is exhaust. I have personally used one on a HEPA installed Miele and can report that the meter reads ZERO same with IQ Air's Air Purifiers. I have not used it on a Dyson but I have never seen or heard of one that WAS tested that does not leak. Miele does not claim a zero reading with the Air Clean Filter.

Thanks for that info, Lucky! Im sure I read somewhere that the particle counters have to be done in a controlled environment. Anyone know roughly what a particle count is for the Air Clean filter?
I recall years ago our Forum Moderator here saying that he sees dirt on the DC07's air in/outlet tubes [behind the dirt bin] based on viewings of various display models in big box stores. How does it get there? Leakage? If I'm wrong maybe Mike W. will correct me. Please do.

That was so long ago, but I think I remember. Before the dyson came to the U.S. and shortly after it introed, T.G. spoke of how wonderful the dyson was. He said that the multicyclones, on the dyson, were so great that NOTHING passes the cyclones. I knew this was bull. I checked dysons by removing the dirtbin/cyclone assembly and looked at the inside of the tube(exhaust end) that runs to the premotor filter. Fine dust coated the inside tube. This was the case on all dysons. What I proved was that debris does get by the cyclones and the bin does not need to be overfilled to do so. I do not recall saying anything about dust on the outside of the machine.
Dyson vacuum cleaners do well at filtering while vacuuming. The problem is when the dirtbin is emptied. The dirt does fly, even though some led others to believe differently. JD's company even knew the dust would fly, because he said to put a bag around the bin when emptying it.
Sorry Carmine but you can't compare Oreck with Dyson. Totally different vacuums. For a start the Dysons are all clean fan systems.
My point was that ORECK despite HS's attacks and disfavor over its operation has passed the test of time for more than 45 years with little to no major changes to its design and function. A testament in my opinion to its classic appeal across several generations of users.

Thank you for the clarification. I opine then based on your observations that the filtration of the cyclones is less than efficient than Tom Gasko lead us to believe. This could account too for the more frequent cleaning maintenance shedules on dyson pre-post motor filters after DC07/14 models. Which could also suggest the cyclone filtration on the later dyson models is still no better than DC07/14.
It's over! You've given away many con’s ways and their trickery’s and thrown many of your cohort independent vacuum cleaner dealer con-buddies under the bus and you've outlived your usefulness. Look around; no consumer wants to talk with you! Where are they? By comparison, go to the site Gasko use to participate in and the dude is an icon amongst the consumer. The consumer is a lot wiser (self-educated) than your old-school days. No-doubt you turned off many consumers to the site. How do I know? Gasko's numbers are probably 200 to 1 (for ever 1 consumer who comes here seeking you out, he had 200 that sought him out). You've outlived your usefulness... you’re livin in the past, retire already - it's over!

I have a problem w/ the example you are using. T.G. is not a good example to prove your point. I know the site you are referring to. He encourages them to purchase bagless Euro Pros, Bissell and HOOVERs. What? Say it isn't so. You see, some of us remember the past.
He put down all these companies and instead promoted dyson. I evaluated the new(at the time) Euro Pro Infinity and its multicyclone design. He put it down. He used it to pick up ashes, then took it back to the store. Later, he would speak highly of it on the site you are speaking of. The same was true of the HOOVER and Bissell. He does not show up now, when people are having problems with their HOOVER Whisper.
He has told people, on the forum you are talking about, to tap the dirt bin, of a bagless vacuum, on the ground to dislodge any dirt. For the record, I would never advise to tap the bin on the ground. When the dyson first came to the U.S., I had said that fine dirt will cake in the cyclones and center tube. I told people, on the previous forum, to tap the side of the cyclone assembly to dislodge fine dust. Carl, remember him, used my advice and found it to be true. T.G. did not like that. Later, I would tell people that if any debris lodges against the Hoover Fusion cyclone, all they would have to do is shake the dirtbin in a downward motion. The debris would fall without mess. Then just dump the contents into the trash. He, and some dyson people, said that debris always stuck and had to be removed with hands.
The people on that site wanted cheap, so he told them what they wanted to hear. Notice how little he talked about dyson compared to HOOVER and Euro Pro Infinity canister/upright? Quite a few knew who he was and made sure they made a point in bring his name up. You were there. What did you say? Motorhead was there.
It is fine if you have a point to make, but I do not like your example, because it does not prove your point.

Actually I believe I gave a splendid example/s.Gasko could be giving the worst advice in the world and yet he had (I’ve not looked an quite a while) a following 100-200 times greater than the rare consumer who’s dared to show their face here seeking advice on anything.Numbers don’t lie, when two vacuum dealers are freely giving advice online and one is ignored and one is sought out.That’s enough proof for me (and for most).Carmine, and others blasted the Abby newbie when he had the audacity to post his liking for the DC26.He posted once, was blasted (or topic blasted) and left.
Again, Model2 was chased out and the guy had 100,000 views just on his DC24 Youtube video.Carmine, Mole, Procare, Lucky1, Retardturtle and even Venson/Severus use this site as a anti-Dyosn platform for two primary reasons…lie of Dyson (for sport) and to lie of Dyson (for profit).Any outsider reading these boldface lies and attacks on Dyson no-doubt stays away.
Do you think Carmine, Mole, Lucky1, Procare, Retardturtle and/or Venson/Severus can prove that Dyson vacuums leak dust (blow dust) from the suction/upstream side?I don’t.
