It measures 12 x 18 x 1 inches nominal with actual dimensions of 11.38 x 17.5 x 0.875 inches. The filter uses a synthetic pleated media bonded to a clay coated paperboard frame and is rated for airflow up to 563 CFM at a maximum velocity of 500 FPM. An integrated frame holds the media securely in the filter slot without additional hardware. Initial resistance is 0.19 inches w.g. at 300 FPM and 0.26 inches w.g. at 375 FPM, making it a low-restriction option for standard forced-air systems. This filter is installed by HVAC technicians and qualified service personnel as part of routine maintenance.\u003c\/p\u003e\n\u003cp\u003eThis filter fits any forced-air heating or cooling unit that accepts a standard 12 x 18 x 1 inch filter slot. It is suited for residential furnaces, air handlers, and heat pumps where moderate particulate filtration is required. MERV 8 performance captures dust, pollen, mold spores, and lint, making it appropriate for residential environments and light commercial spaces with standard air quality demands. The synthetic media maintains structural integrity across temperature swings up to 150 degrees F, which covers the full operating range of most residential HVAC equipment.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMERV 8 filtration captures dust, pollen, mold spores, and lint\u003c\/li\u003e\n  \u003cli\u003eSynthetic pleated media delivers consistent airflow with low initial resistance of 0.19 inches w.g. at 300 FPM\u003c\/li\u003e\n  \u003cli\u003eIntegrated clay coated paperboard frame holds shape in the filter rack without sagging\u003c\/li\u003e\n  \u003cli\u003eRated to 563 CFM with a maximum velocity of 500 FPM\u003c\/li\u003e\n  \u003cli\u003eMaximum operating temperature of 150 degrees F suits standard residential HVAC equipment\u003c\/li\u003e\n  \u003cli\u003eUL 900 listed for fire safety compliance\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with any forced-air HVAC unit that accepts a standard 12 x 18 x 1 inch nominal filter.

Slide the filter into the rack with the airflow arrow on the frame pointing toward the blower. Check manufacturer service intervals and replace at or before the filter reaches its final resistance of 1 inch w.g.
