These 16" x 25" x 2" fiberglass furnace filters may look like the same flimsy 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. These affordable fiberglass filters are also available in 1 inch and custom sizes.
