The BNX TruFilter 14x25x1 MERV 13 air filter is an electrostatic pleated 1-inch HVAC filter sold in a 6-pack. The 14x25x1 size is common in older residential HVAC systems and many modern townhomes. MERV 13 filtration captures allergens, pollen, mold spores, bacteria, smoke, and pet dander down to 0.3 microns.
It fits any 14x25x1 return-air grille or HVAC slot. The 6-pack provides a year of monthly replacements. Electrostatic synthetic media gives higher filtration than standard pleated filters without significantly restricting airflow through the HVAC system.
BNX is an American air filter manufacturer producing the TruFilter line in the United States.
