The Genuine Lennox X6672 16x25x5 MERV 16 Healthy Climate Furnace & AC Air Filter is a replacement air filter for the Lennox HCC16028 Healthy Climate True Fit Cabinet. This furnace filter measures approximately 16x25x5 and features a MERV 16 rating for the reduction of airborne particles. A higher MERV rating results in a higher degree of air filtration, meaning this filter can trap dust, dirt, pollen, and other pollutants that can lessen air quality. This pleated air filter is also compatible with air cleaners from Honeywell, Carrier, and Trion Air Bear that accept 16x25x5 filter media. This Lennox Healthy Climate filter is a genuine OEM part and is made from high quality material. Be sure to replace this pleated air filter every 6 to 12 months to achieve optimal results.

works well at reducing dust and gives nice clean air.

Delivery is fast and the filters are much cheaper than the local HVAC company that does my yearly furnace tune up. I've used Filters Fast for the past 3 years.
