16x25x5 MERV 10 GeneralAire 5FM1625 Replacement Filter for MAC1400 (#4511) 4541

The Generalaire 16x25x5 HVAC filter arrived in good shape and fit perfectly. Ordering this size filter online was a challenge on other sites because most offered filters they claim would fit either 4 or 5-inch widths and I wanted an exact fit. The ordering process and free shipping were a welcome change from Amazon and other sites. When I had my A/C system serviced, I was told I would be charged $120 for a replacement filter, and by ordering through Atomic I saved a bundle. Of course it will take a year or so to truly evaluate the filter, but so far, so good.
