Blueair filters are like having three filters in one. The filters trap six times more dirt than filters in typical air purifiers. The reason is the filter’s progressive structure. Most filters from other air purifier manufacturers are thinner and usually consist of the same size fiber throughout. Blueair filters have millions of ultrathin fibers in three different sizes. The first layer captures larger particles like pollen & dust. The second and third capture smaller particles like bacteria and exhaust.
Blueair filter design resists loading or clogging and continues filtration at peak performance levels longer. Due to the exclusive design, Blueair filters lock in particles, once captured, the particles will not be re-released into your environment, even under heavy loading conditions.
When the filter needs to be replaced (every six months), just open the lid, lift out the old filters and drop the new ones in. No screws, hooks or tools and less than one minute of your time is required. Blueair filters require no weekly additives or filter washing. The 400 SmokeStop filter contains highly activated carbon, recommended for use in rooms where heavy gaseous pollutants such a cigarette smoke or VOC’s are present.
