Honeywell HRF-K2 ("K") Replacement Air Purifier Pre-Filters are 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.
2 filters in each pack
Fits many models, including: HFD300, HFD310, HFD320, HFD323-TGT, HFD-120-Q, and more.
For best cleaning performance, replace your pre-filters every 3 months.
