The Honeywell HRF201B pre-filter can be used in a variety of Honeywell Air Purifiers. A built-in carbon pre-filter layer has been added and can be instrumental in capturing 99% of airborne particles at 2 microns. For the very best performance, it is recommended that the HRF201B HEPAClean Replacement Filter U be replaced every 4 months. HRF201B Replacement Filters are compatible with the following units: HHT270 and HHT290.

Honeywell Store was a great experience. When I called because I didn't recognize the charge on my credit card, they immediately called me back and offered assistance. Imagine that- a real live person. I will come here for all of my filter replacement needs.
