The 3-stage filtration cartridge is contained and protected in a durable steel box. In stage-one, a foam pre-filter captures large particulate matter. In the second stage, the HEPA filter traps more of the harmful and irritating particulate like pet dander, pollen and smoke. Finally, in the third stage, the activated carbon adsorbs chemical or gas-based pollutants. 

The filters are easy to access and change. Once locked into place, the filter is completely sealed, ensuring that no polluted air escapes from the box. The baked thermostat powder finish on the box itself provides a durable, long-lasting housing that will not off-gas chemicals, providing truly clean air to the surrounding environment. 

Though continuous operation is recommended for optimal indoor air quality, this unit does feature an illuminated on/off switch. 

There is an optional VOC filter upgrade available for this unit.
