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?

Just poking my nose in to say "I told you so:"

Opinion to follow,

I think Dysons look pretty neat.  I have never used one but would like to try one just for the heck of it.  I wish they were a little more wallet friendly for a plastic machine, but hey they are all going plastic. 

I think the comment in an  above post is right on.  Even if a machine is totally sealed, once you go to empty the dust container, it is going to be open so it's all moot anyway.

Look at Filter Queen.  A fine machine, great suction, good durability, good filteration.  BUT--you end up taking it outside and dumping it like a shop-vac.  Something seems lost in the process for me.  The old Kirbys were not so great filteration, and then you dumped them on a newspaper and let more dirt fly. Still there is nothing that I could say bad about a Kirby.  But I will always admit to being partial.  The Rainbow was supposed to trap all the dirt in water washed air.  But there is some dirt that is hydrophobic and would escape in the air path.  It was good in theory. 

In the end you could do worse than a Dyson,  you may be able to do better; but it's you that you have to please.  If you like it, it works for you, you can afford it. Go for it.

Thank you all, and it's good to know the Dyson is completely sealed. It's not so much that it's not releasing dirty air back, it's that they took the time to put quality construction into the machine and design, which is evident of it being completely sealed. I was just curious more than ever, but thanks all you guys :D

   Dyson as well as other bagless that have come in for repair have had leakage and don't completely seal. At first they will , then will eventually lose their seal. As evidenced by dust on the body and where the bin is sitting. The worst that I have seen in leakage was the Fantom while it was uot. Dyson is not as bad but does leak..

I have a feeling that this was due to A.) Improper use B.) Improper maintenance C.) Them being older models. Their canisters - which I am mainly interested in - are VERY simply in their seals (only two through out the whole system in terms of cyclone bin assembly connection - and thus given that their newer uprights seal well - from what I've gathered, I could only imaging their canisters are excellent. Again, just as I have been logically enlightened on this forum, if it leaks a TEENY bit out, big deal? As soon as you go to change a bag or empty the cup you'll get a TEENY bit of dust flying around anyways, so it's not that big of a deal. Still, complete sealing's always nice B)

If the issue is zero blowback, the best bet is a central vacuum that exhaust to the outside of your living space. It doesn't get any better than that.

Hi Severus:

Good link to allergy buyers web site.  If I recall, you posted this site before here.  And I was impressed tho may not have mentioned at the time.  Looks like MIELE and SEBO vacuums get the highest andmost number of excellent ratings, even the newest MIELE S7 upright series, even if not all their [MIELE/SEBO] models are actually HEPA rated and/or sealed vacuum systems.  Thanks for posting.

I agree with you that the allergy sites tend to be good sources of information for allergy sufferers.    They should get a lot of feedback from their customers about what works and what doesn't.   However, they don't seem to be nearly as rigorous as CR in their testing.

I would agree that people with serious medical conditions should stick with a bagged vacuum or even a central vacuum.

Miele's superior filtration does come at a price.   I'm not sure, but Riccar and Simplicity may have filtration comparable to Miele.  You could always visit the Tacony vacuum museum in St. James, MO and get one at the factory store.

The full size RICCAR/SIMPLICITY uprights and canisters boast in writing that they are 100% sealed systems with HEPA S-Class ratings.  Interestingly, CR rates the bagged RICCAR Brilliance [succesor to Radiance] and SIMPLICITY Synchrony Premium uprights very good for emissions rather than excellent, as one might expect with 100% sealed HEPA S-class.

Hi,

Is there a comprehensive guide as to acceptable to harmful levels of vacuum filtration? How many microns retained actually  constitute excellent, very good and good filtering service? CR's excellent to very good rating slots would cause me as a consumer to think there's little difference.  What does a micron or  two missed in the filtration process really mean to a serious dust allergy sufferer as opposed to machines that obviously don't contain dust well?
