Blueair Smokestop Filter for Blueair 500/600 Series Air Purifiers, Set of 3

I tried the Smokestop filter for the Blueair 402 model, but these are the exact same, only different sized to accommodate the larger models. If you have any issue with odors or cigarette smoke, this is the filter to get.

I had an extreme situation where there was a methane leak in my neighborhood. The fumes were claimed by authorities to be "safe," but I and many other neighbors suffered from headaches, dizziness and nauseousness. The fumes burned at your eyes and it was pretty unbearable. Well, turns out this was to recur for the next few nights, and with no other place to stay, I invested in a Smokestop filter to temporarily replace my particle filter. It was INCREDIBLE. Immediately, all the fumes in the room were swept up by the Blueair and I was able to spend my time in this room with no health issues. (Whenever I left the room to another part of the house, all the previously mentioned symptoms returned.)

First of all, I have been using the BlueAir 500 series air purifer for almost three years for pet dander and smoking on the weekends. I stumbled across these filters and was pleasantly surprised at the price, which was 50 to 80 dollars cheaper. Purchased the Smokestop filters in Mar 2011 and although the outer mesh on the airflow out side was white and not black and its texture was not as course, the rest of the filter seemed like previous ones I had bought from another online retailer. Used it for 2 weeks in two rooms for pet dander and then on Friday/Saturday nights in a basement for a total of 3 packs from 1 smoker over the two weekends. When moved the air purifer to the other rooms where I don't smoke, within 10 minutes the room smelled like smoke. Amazon was really great about providing a replacement set of filters but again, these performed the same and within 10 minutes, the room would smell like smoke. I have gone back to purchasing the filters from the other online retailer...Read more

The other regular particle filter version works great at filtering out dust. However, with this smokestop filter, it gets rid of odors and general outdoor smog that gets its way into your house. The room smells better after running it for less than an hour.

Plus: it makes the unit run quieter as the carbon filter section actually acts like a sound baffle to block out some of the fan noise. Usually with the regular particle filter, even on low speed for my 650E, I can still hear a whirling fan sound. With this filter, I can hardly hear it and can leave it on low for the whole night. With the regular particle filter version, when the electronic sensor would detect VOCs (volatile organic compounds)/odor, it would kick the fan on high and it would be a long time until the odor is diffused/lessened, for the fan to slow down. With the smokestop filter, the VOC/odor gets reduced in a few minutes and the cleaner does not stay on high for long.

Minus: it...Read more
