The Honeywell Replacement Pre-Filter is a very helpful complement to the IFD filter used in Honeywell QuietClean and AirGenius Air Purifiers. These optional pre-filters trap larger particles before they reach the IFD filter in your QuietClean or AirGenius air purifier. In the process， they deodorize the air that passes through them and capture some harmful gases and volatile organic compounds (VOCs) as well.
