The Honeywell FC40R1045 14x25x5 Replacement Grille Filters replaces the Expandapac filter #FC35A1118 that was used in model F35R1069. This product is a grille filter and has a nominal size of 14" x 25" x 5". The actual size is 13 3/4" x 24 3/4" x 4 3/8".
These filters are a high-efficiency alternative to one inch filters because they have a larger media capacity, which allows for greater dust holding ability. There is no assembly required for this product, it simply inserts into and out of the existing return grille.
They also allow you to replace your old filter with ease, without having to remove the grille, simply push it aside. Please note that this product will allow a 7" depth behind grille to provide space for the deeper filter and air flow through filter. These filters last up to 6 months or more depending on use.
