The synthetic filter media is supported by a wire backing that holds pleat shape under airflow, maintaining consistent performance across the service life of the filter. The beverage board frame provides rigidity for a secure fit in standard filter housings. Airflow capacity is rated at 1,050 CFM, with initial resistance of 0.20 inches w.g. at 300 FPM and 0.28 inches w.g. at 375 FPM. HVAC technicians and facilities maintenance personnel are the primary installers.\u003c\/p\u003e\u003cp\u003eThis filter is suited for use in forced-air heating and cooling systems where mid-range filtration efficiency is required. MERV 11 captures particles including dust mite debris, mold spores, pet dander, and fine dust, making it appropriate for residential applications with allergy concerns or light commercial environments. The nominal size of 20 x 20 x 1 inches fits a wide range of standard filter slots. The manufacturer designates this filter for use with any unit accepting that nominal size.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMERV 11 efficiency rating captures fine particulates including mold spores and pet dander\u003c\/li\u003e\n\u003cli\u003eWire-backed pleated design maintains pleat geometry under operating airflow\u003c\/li\u003e\n\u003cli\u003eSynthetic filter media for consistent filtration performance\u003c\/li\u003e\n\u003cli\u003eBeverage board frame with integrated construction for a secure housing fit\u003c\/li\u003e\n\u003cli\u003eRated 1,050 CFM maximum airflow capacity\u003c\/li\u003e\n\u003cli\u003eUL 900 listed filter media\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eRated for use with any HVAC unit accepting a 20 x 20 x 1 inch nominal filter size.
