Carbon Pre Filter K Compatible with Honeywell HRF-K

Carbon Pre Filter K Compatible with Honeywell Air Purifiers

Carbon Pre Filter K is a compatible replacement pre-filter designed for select Honeywell air purifier models. This pre-filter helps capture larger airborne particles while effectively reducing odors and VOCs. The potassium permanganate calcite layer also deodorizes the air, improving indoor air quality.

Using a pre-filter can help extend the lifespan of the main HEPA filter by trapping larger particles before they reach the primary filtration layer.
