With a nominal size of 20x25x1 inches and an actual size of 19.5 x 24.5 x 0.75 inches, it fits standard filter slots calling for a 1-inch filter in that footprint. The MERV 11 rating means this filter captures finer particulate than basic fiberglass or MERV 8 panels, making it appropriate for households with pets, mild allergy sensitivities, or systems requiring a step up in filtration efficiency without creating excessive static pressure drop. Licensed HVAC technicians and facility maintenance personnel are the primary installers.\u003c\/p\u003e\u003cp\u003eThis filter is suited for forced-air heating and cooling systems in residential homes, apartments, and small commercial spaces. It installs in the return-air grille or air handler filter rack wherever a 20x25x1-inch slot is specified. The 10-pack format supports scheduled preventive maintenance programs, reducing the need for frequent individual purchases and keeping replacement filters on hand for regular change-out intervals.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMERV 11 filtration captures finer dust, pollen, mold spores, and pet dander compared to lower-rated filters\u003c\/li\u003e\n\u003cli\u003eNominal size 20x25x1 inches fits standard return grilles and air handler racks designed for that slot\u003c\/li\u003e\n\u003cli\u003eActual size 19.5 x 24.5 x 0.75 inches ensures proper fit without forcing or gaps\u003c\/li\u003e\n\u003cli\u003ePleated media design increases surface area for improved particle capture and extended service life\u003c\/li\u003e\n\u003cli\u003eSold in a 10-pack quantity for efficient preventive maintenance stocking\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement for residential and light commercial forced-air HVAC systems that accept a 20x25x1-inch pleated air filter in return-air grilles or air handler filter racks.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eAir filters of this type are installed and replaced by HVAC technicians or qualified maintenance personnel following system manufacturer guidelines. Power down or set the thermostat to the off position before opening the filter rack or return grille to prevent unfiltered air from passing through the system during service. Verify airflow direction marked on the filter frame aligns with the direction of air movement into the unit before closing the access panel. Follow local codes and system manufacturer recommendations for replacement intervals, typically every 60 to 90 days depending on system load and air quality conditions.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 20 x 25 x 1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActual Size\u003c\/strong\u003e: 19.5 x 24.5 x 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMERV Rating\u003c\/strong\u003e: MERV 11\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: FILTER KING\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: AF20x25x1-M11\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Filter King","offers":[{"title":"Default Title","offer_id":51716746314034,"sku":"AF20x25x1-M11","price":15.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4f5cc2bafe34b96d3e2d0571e1a0e978_dba6aa81-2011-450e-905e-4a3485db98a8.jpg?v=1788531191","url":"https:\/\/voomisupply.com\/products\/filter-king-af20x25x1-m11-merv-11-air-filter-20x25x1","provider":"Voomi Supply","version":"1.0","type":"link"}
