Rated MERV 12, this filter captures over 90% of airborne particles between 3 and 10 microns and 80% to 90% of particles between 1 and 3 microns. The filter media is electrostatically charged to attract contaminants and is built on a moisture-resistant beverage board frame for structural integrity. This six-pack is manufactured to exact dimensions and is suited for HVAC technicians and homeowners replacing non-standard filter sizes.\u003c\/p\u003e\n\u003cp\u003eThis filter is built to fit duct openings and filter housings requiring an exact nominal size of 11.5 x 21 x 1 inches, with an actual size of 11.5 x 21 x 0.75 inches. The custom construction may use tape to join frames depending on the final dimensions. It is appropriate for residential forced-air systems, light commercial air handlers, and any installation where standard nominal sizing does not apply. Filter replacement is recommended every one to three months, with more frequent changes advised in environments with pets, high dust loads, or occupants with respiratory sensitivities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMERV 12 filtration captures lint, dust, pollen, pet dander, mold spores, smoke particles, bacteria, and virus carriers\u003c\/li\u003e\n  \u003cli\u003eCaptures over 90% of particles between 3 and 10 microns and 80% to 90% of particles between 1 and 3 microns\u003c\/li\u003e\n  \u003cli\u003eElectrostatically charged pleated media resists bacterial and mold growth on the filter surface\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty, moisture-resistant beverage board frame with reinforced two-part construction for durability\u003c\/li\u003e\n  \u003cli\u003eCustom-cut to exact dimensions  -  not a nominal fit; actual size is 11.5 x 21 x 0.75 inches\u003c\/li\u003e\n  \u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCustom-made to fit HVAC filter housings and return-air grilles requiring a nominal size of 11.5 x 21 x 1 inches.

Always shut down the HVAC system at the thermostat before removing and replacing the filter.
