Key Features

GENUINE BLUEAIR CLASSIC 400 REPLACEMENT SMOKESTOP FILTER: Created for Classic 400 series air purifiers to guarantee optimal performance and maximum filtration efficiency; compatible with Classic 403, 405, 480i and 450E

SUPERIOR QUALITY HEPASILENT FILTER: SmokeStop carbon filters remove 99.97 percent of airborne particles, down to 0.1 microns in size due to Blueair’s unique HEPASilent filtration technology

UNCOMPROMISED GAS POLLUTANT REMOVAL: Designed to absorb common pollutants like VOCs, exhaust, smog, odours, smoke and airborne chemicals through high amounts of activated carbon - effective for a healthier home environment with high filtration efficiency

NATURALLY ANTIBACTERIAL: Free of chemical additives, this filter uses pure, high-porosity coconut carbon to remove odors - filter fibers resist bacteria and mould growth

UP TO 6-MONTH FILTER LIFE: To maintain optimum performance, we recommend changing your filter once every 6 months when used 24 hours a day; blueair filters keep your air purifier in the best working condition; alternatives cannot be assured for quality
