The BNX TruFilter 14x18x1 MERV 13 air filter is an electrostatic pleated 1-inch HVAC filter sold in a 6-pack. The 14x18x1 size is common in apartments, condos, and smaller residential HVAC systems. MERV 13 filtration captures allergens, pollen, mold spores, bacteria, smoke, and pet dander down to 0.3 microns.
It fits any 14x18x1 return-air grille or HVAC slot. The 6-pack covers a year of monthly replacements at standard-density allergy-control intervals. Electrostatic synthetic media maintains airflow while delivering higher filtration than standard pleated filters.
BNX is an American air filter manufacturer producing the TruFilter line in the United States.
