Score: 75/100Rankings

The Honeywell HRFSP1 is an enhanced S-series air purifier filter designed to target pet odors using activated carbon and zeolite. It reduces pet odors up to 3.5x faster than standard filters when used with a pre-filter and HEPA filter in compatible Honeywell units. Ideal for multi-pet households needing faster odor control alongside HEPA filtration.

The Honeywell Premium Odor-Reducing Air Purifier Replacement Pre-Filter (HRF-APP1) is a single-pack replacement pre-filter designed for Honeywell tower air purifiers. It captures larger airborne particles like dust and pet fur while using activated carbon and zeolite to reduce odors, VOCs, and harmful gases. Ideal for homes with pet odors, cooking smells, or smoke to pre-filter large particles and deodorize before air reaches the main HEPA filter.
