Best of all, the pre filter never needs to be replaced for easy, cost free maintenance. The purifier's IFD filter removes 99.97 percent of all airborne particles that pass through, such as pollen, cat dander, household dust, tobacco smoke, and mold spores. No more dust particles in that glint of sunlight, this Honeywell is equipped with a built in ionizer that grounds airborne dust for quick vacuum cleanup.
An electronic filter check indicator shows when it's time to clean the pre filter. Plus, an LED touch button control offers three fan speeds for fast filtering and whisper quiet air purifying.
