Smokestop units ship with one set of filters, the smokestop filters. The smokestop filters include both the particular filtration and the activated carbon for gas and odor removal.

A perfect bedroom companion, the Blueair 203 packs a complete, high-performance air purifier into a beautifully compact design that’s incredibly quiet. But you don’t have to leave the Blueair 203 in the bedroom. It’s also great in small areas and workspaces to get rid of pesky airborne allergens, such as pollen, dust, smoke, mold spores, pet dander and other impurities. All that remains? Impeccably clean air.
 
Design:
The union of visually pleasing form and effective function is a hallmark of Swedish design, and Blueair is no exception. The Blueair 203 is designed for maximum performance in small rooms. Available in silver or white/dark grey, it suits your distinct style of living.
Technology:
Blueair's patented HEPASilent technology combines the best features of electrostatic and mechanical filter technology to enable the delivery of more clean air at a faster rate with less noise. Phenomenally low power usage minimizes energy consumption. Plus Blueair air purifiers actually reduce the levels of ozone in indoor air.
How it Works:
Air is drawn into the unit via an ultra-quiet fan. Airborne particles pass through an ion chamber and are charged to ensure that they adhere effortlessly to Blueair’s progressive three-stage filter. Cleaned air that is free of impurities is recirculated into the room.
