Blueair Smokestop Filter for 400 Series Air Purifier Save 14% Off

You''re probably completely shocked that this Smokestop Filter costs as much as it does. But trust me, if you have any problems with odors, it''s worth EVERY penny.

I normally use the regular Blueair filter for the 402, but I purchased the Smokestop after my neighborhood was flooded with horrible fumes from a nearby methane gas leak. The authorities deemed the gases as harmless, so no evacuations were ordered. However, being very sensitive to fumes of any kind, I became very ill. With no other place to go, I put the Smokestop filter into my 402 and moved the air cleaner into my smallest bedroom, where I camped out for the next couple of days. A trip to any other room of the house left me feeling nauseous, dizzy, with a raging headache and difficulty breathing within minutes (but the fumes were "harmless"!!). The room with the Blueair equipped with the Smokestop filter was absolutely free of odor. It was incredible.

Since not everyone has methane gas leaks permeating their homes (thankfully!), you may never get the chance to test the filter in this way. But it no doubt works wonders with cigarette smoke and other offensive odors that waft into your home.

The filter has 2 "chambers." One filled with activated charcoal, and the other with the familiar Blueair patented white filter. So it doesn''t just stop with odors, it still cleans particles from the air with great efficiency, and best of all, Q-U-I-E-T-ly. Just remember to change it after 6 months, even if it means going back to the regular (and cheaper) filter. Happy breathing!

SEPT. 2008 ADDENDUM: I had another fume problem, this time, toxic deck sealant fumes from a home repair seeping into the house. I purchased another Smokestop filter and this time I noticed an odor coming from the filter itself. It''s not horrible, but I had become so sensitive to odors after a week of sealant exposure that it made me feel sick. I left the Blueair on high and it has reduced the smell after a few days. To be fair, despite the filter smell, the deck sealant odor was neutralized. And finally, I have a balcony-smoking neighbor, and as soon as secondhand smoke wafts into my bedroom, I turn up the Blueair and the smoke odor is gone in a flash. Just be aware of the initial odor from the filter itself. I''d say I''m dropping my rating to 4 stars, or 3.8 if I could.

Difficult to get a bargain with these but buying thru Amazon offers dependability with the order. Reasonable shipping.

If given the option to rate with fractional values I''d give this a 3.5 star rating. Blueair filters are extremely expensive compared to their competitors and their warranty requires that filters be replaced every 6 months, which is often more often than needed. If you are extremely sensitive to noise the Blueair filters offer some of the lowest noise levels of any air filter on the market, but one has to pay dearly for this feature. If you already own a Blueair filter there are only two choices available to you: the particle filter at $60 and the smokestop filter at $120; there are no third party vendors. The smokestop filter has 2 pounds of activated carbon to control gaseous pollutants and odors in addition to the HEPA filter found in the cheaper particle only filter. The smokestop filter also has a foam prefilter in the back that can be brushed to removed dust buildup; thus, it will probably last longer than the particle filter, which lacks a prefilter (although if you choose to use the filter for more than 6 months you void the warranty). The particle filter has absolutely no activated carbon so if offers zero protection from gaseous pollutants and most users will be better off with the smokestop filter unless that are also running other air purifiers in conjunction with the Blueair filter. The smokestop filter does a good job and provides full spectrum filtration, the only negative feature is that it is overpriced compared to filters of similar quality for other air purifiers.

These filters are very good. As well as trapping a ton of particulate matter, they also freshen the air wherever smokers smoke. Highly recommend if you smoke, have a wood burning fireplace or cook a lot.

I had been buying this product direct from the company because my fiance is alergic to smoke and I am a smoker. Product works great and I found that it''s a lot cheaper on Amazon.
