Filtration systems?

[lori_ann]

Through my search I'm hearing of different filtration systems... With my allergies I may as well get something that will help with this...

So, can anyone tell me which is better (or if there's something even better than this) and why?

the Hepa vs the electrostatic filtration.... from what I'm reading in this article is sounds like the electrostatic is the better choice, but then, I'm not sure...

I know you probably have your mind made up, but this is just for your information.


 


<span style="font-size: 14px;">From the Simplicity web site:</span>


 


<span style="font-family: Arial, Verdana, Helvetica; font-size: 12px; font-weight: normal; line-height: 16px; background-color: #99bfe5;">A second popular form of filtration on the market is electrostatic filtration. Electrostatic filtration is a super-efficient medium designed for high airflow performance with a unique quality that attracts dust particles.</span>


 


It is a fact that the new Kirby bags are made of this very same electrostatic HEPA material. The Kirby bags actually filter down to .1 microns.


That's right, The air in your house will be much cleaner after you finish vacuuming with a Kirby than before you started. Nothing but totally clean air gets through the Kirby Electrostatic HEPA bag.

Filtration

in a vacuum should be a sealed system. The Aerus Platinum is a sealed system with the bag being 94% down to true HEPA. Behind the Bag is a HEPA filter and Carbon Filter and behind the motor is a long lasting HEPA. This will give clean air leaving your vacuum. Many cleaners proclaim and have HEPA bags but are not sealed systems. Kirby still will spew out particles that the Bag won't stop. Motor carbon dust for one. The Platinum will help allergies.

thank you

both.. Stan, no I do not have my mind made up! LOL, hence the further research and questions!

Tig... I just looked up the Aerus Lux... that machine is well over a grand, I can't afford that! Not to mention it's very negative reviews. The reason Stan mentioned the Kirby is there is one used on Ebay thats been reconditioned for a decent price.

With regard to Kirby, the HEPA bags work in all Kirby machines from the Heritage II onward, if I remember correctly. Certainly they work in my Heritage II Legend.

As for filtration, my only reservation would be this: most canisters and clean-air uprights have a multi-stage filter system: the bag, a pre-motor filter and a post-motor filter. In theory that means that a sealed system of this type ought to filter better than one that has only a HEPA bag, though I'm not sure how that turns out in practice. I do know that particle-counter readings from Simplicity, Miele and Sebo canisters are very low indeed, and the three are about equal with each other.

As a kid, my mother and grandmother swore by Filter Queen, and indeed they do a very good job - I still have one, and it never blows dust or develops that stinky, dusty, cat-fur odor that some other vacuums do. That said, my Simplicity and Kirby don't stink either. (Well, the Kirby does if I use the old paper bags, but not the new HEPA ones - and they restrict airflow less anyway, so they're just better, other than being a little expensive.)

As Crazy As It Sounds......

most vacuums that cost a grand will save you money in the long run because they are made to last. something like a simplicity synergy will last as long as 15 to 20 years

Well, not all expensive vacuums last. The price doesn't justify it always.

Yet again Lori, that Simplicity link is misleading.

Electrostatic filtration FORMS part of the HEPA filter and is usually ALSO FOUND in the dust bag that magnetically charges and allows dust to cling to the material AS WELL AS ensuring air flow at the same time. Miele dust bags for example are Electrostatic in nature and have always been since their earlier days of the IntensiveClean types before the HyClean bags were introduced.

BOTH electrostatic and HEPA filters trap dust particles though. Electrostatic filtration however will NOT absorb stronger odours that sit in the bag or bagless canister - so things like pet hair that will sit rotting in a dust bag will eventually permeate back into the room. HEPA filters eliminate the smell of rotting dog/pet hair in general.

Also HEPA and S-Class are the same, just different names - S-Class was first before HEPA came along.

At the end of the day, a bagged vacuum cleaner is going to be better for dust allergies. It is also better for those with breathing allergies where dust is concerned.

Even better than HEPA filtration...

Is ULPA filtration.

ULPA filters are used on some of the specialist vacuum cleaners from Nilfisk.

These filters are not practical for the average vacuum cleaner user and are not available for most vacuum cleaners.
