Does a great job of filtering the incoming furnace air. Fits exactly in the frame. I change mine every 6 months due to my wife allergies
I order all my filters from Atomic Filters. Their prices are always very competitive and shipped in a timely manner.
Fit Like A Glove,Very Nice! Will purchase again.
Quality of filter
While the replacement filter appears to be made by Lennox, the original Lennox filter we removed from the unit which is only a year old, was of higher quality than the replacement. The layers of filter element on the new one were spread further apart which made for a floppy-like accordion and harder to install in the mounting cartridge. The new filter also had exposed wires on each side which cut my hands while I was installing. To sum up, the new filter might say Lennox, but the quality of the filter is not the same as we had. Not sure if the manufacturer has cheapened the product or has several firms making it now.
