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.

For the gadget-happy, the popular Blueair 270E offers the same reliable air purification performance as the incredibly quiet Blueair 203 model, but it comes with a handy remote control unit and digital display.The easy-to-use remote control and digital display system give you instant feedback of particle detection, air purifier speed and timer operation. So you don't have to leave your comfortable spot at your desk, on the sofa or in bed to change the speed setting. Just point and click.Electronic particle and gas sensors confirm that the unit is effectively removing allergens, such as pollen, dust, smoke, mold spores and pet dander, from the air. And you can see when it's time to change the filters on the electronic display.
 
Design:
The union of visually pleasing form and effective function is a hallmark of Swedish design, and Blueair is no exception. The Blueair 270E is designed for maximum performance in small rooms. Available in 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.
