Blueair Smokestop Filter for 402 Air Purifier

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.

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.
