Flanders 24x24x1" Disposable Fiberglass Air Filters MERV 5

Our least expensive air conditioner filter, and it starts at at only $3.24 each!

These fiberglass filters may look like the same flimsy fiberglass furnace filters you've seen elsewhere, but look again. These disposable air filters are rigidly constructed using metal grids that are thermally bonded to the internal sides of a one-piece kraft fiberboard frame and the filtration power comes from a progressively dense fiberglass or polyester media to maximize dust holding capacity. Sold in cases of 12 filters. Also available in custom sizes.
