Funmit
The Funmit HPA300 is a third-party HEPA filter replacement designed as a compatible substitute for Honeywell HPA300 series air purifiers, serving as a drop-in replacement for the official HRF-R3 filter. It captures particles down to 0.3 microns at up to 99.97% efficiency and matches standard dimensions for these systems. This single-unit cartridge allows users to maintain their large-room air purifiers without purchasing expensive OEM parts.
