Return air grille filters can be hard to find and are oddly shaped. Lucky for you, we make replacement easy. On most "grille” cut filters, the larger dimension will be listed first. However, if you were to take the actual measurement, it's likely 7/8" smaller than what is printed on the filter. Some measure a bit smaller—5/8" smaller to be exact. Many models of return air grille filters have been discontinued by manufacturers over the years, making them harder to find. Luckily, we have many return air grille filters. Our grille filters are the recommended replacement made by AAF Flanders. So check out our impressive selection of return air grille filters today—you won’t be disappointed.
