Universal pre-filter for Honeywell purifiers

The Honeywell HRF-APP1 is a replacement pre-filter designed for round QuietCare and SilentComfort air purifiers. It fits the 17000, 18150, 50000, 40100 and 40200 series units. Buyers with HPA tower models cannot use this filter.

Activated carbon and zeolite layer targets odours

The filter uses activated carbon and zeolite to deodorise air and absorb common household gases and fumes. It also traps larger particles such as dust, lint, fibres and pet fur. This protection extends the service life of the main HEPA filter inside the purifier.

Cut-to-fit design serves multiple series

Each sheet measures 8.39" x 8.27" x 2.75" and can be trimmed to produce one to eight pre-filters depending on the specific purifier model. Replacement is recommended every three months for best performance. The pack ships as a four-piece display tray.
