Includes both the inner and outer filter required for SmartAir's purification stages.
Outer: HEPA-Type filter with up to 99.9% single pass capture for dust, pollen, mold, bacteria, and any airborne particles down to 0.3 Microns.
Inner: Activated Carbon filter coated in a photo-catalyst. Reacts with UV light, charging the surface with free radicals, turning it into a pollutant destroying wall.
Recommended to be replaced every 6 months. Helps purification stay at its optimal level.
