Lennox Healthy Climate PMAC (Pleated Media Air Cleaner) MERV 16 replacement furnace filter - X5424. Fits the PMAC-20C model.
The Lennox Healthy Climate boxed media air cleaner uses a MERV 16 filter to capture particles down to 0.3 micron. In most home environments, this filter only needs to be replaced every 12 months.
This is an excellent filter for someone who wants a significant upgrade over standard fiberglass filters from the hardware store. The PMAC-20C pleated furnace filter 25" x 20" x 6"is a direct replacement for the Aprilaire / Spacegard 201 filter media used in the air cleaner model 2200.
