14x20x5 MERV 11 Grille Filter (2 Pack)

98% efficient filtration media capturing particles as small as 0.3 microns before they can collect on your coils. High-efficiency alternative to one-inch filters. Larger media capacity allows for greater dust-holding ability. No assembly required. Easily inserts into and out of existing return grille. Allow a 7amp;amp;amp;amp;quot; depth behind grille to provide space for the deeper filter and air flow through filter. This is an aftermarket filter.
