The SmokeBlock filters offer extra protection against wildfire smoke particulates and emissions (toxic gasses, smog and odors), in addition to protection against airborne particles (dust, smoke, pollen).
SmokeStop filters can be used in Pro air purifiers instead of the standard Particle filters. The SmokeStop filters offer extra protection against gas, smoke and VOCs, in addition to the standard protection against airborne particles (dust, smoke, pollen).
DualProtection filters can be used in Classic air purifiers, instead of the standard Particle filters. The DualProtect filters offer protection against gas, smoke and VOCs, in addition to the standard protection against airborne particles (dust, smoke, pollen).
