Genuine OEM Honeywell Product
The Honeywell Pre-filter is capable of capturing large airborne particles and is an ideal replacement for all Honeywell Commercial F118C Media Air Cleaners. The pre-filter is especially effective as it's capable of capturing larger sized particles such as dust, lint, fibers and pet dander before they ever have the chance of passing through the Media Filter. In return, this increases your Media Filter's lifespan significantly and allows for maximum efficiency. Accept no imitations and achieve the ultimate in peace of mind with a Genuine OEM Honeywell product.
