Customer Reviews:
Works very good.
Collected by Trustpilot.comIt keeps the air very clean and doesn't have to be replaced often.
Collected by Trustpilot.comI like the MERV 13 filter kit for my Air cleaner system. Firs and works perfectly.
Collected by Trustpilot.comHigh quality filters and UV bulbs--prefect for the Lennox furnace/AC unit. Highly recommended.
Collected by Trustpilot.comI buy the X8797 from filtersfast because it saves me money! Kit was received in excellent condition. Very easy to install. Why pay your local AC guy, who marks up the price of the kit plus charges for labor, when you can save money and do it yourself. Thanks filtersfast!
