Lennox X0444 mev10 Filter - 2-Pack - 28 inch x 17 inch x 6 inch - Genuine Lennox Product

Fits the smaller PMAC-12C model. The Lennox X0444 Healthy Climate boxed media air cleaner uses a MERV 10 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-12C pleated furnace filter is a direct replacement for the Aprilaire / Spacegard 401 filter media used in the air cleaner model 2400.
