It captures a broad range of airborne particulates including dust, pollen, mold spores, pet dander, and fine dust particles common in forced-air systems. The nominal size is 20x36x1 inches with an actual size of 19.5 x 35.5 x 0.75 inches. At MERV 11, this filter strikes a balance between filtration efficiency and airflow restriction, making it a suitable choice for systems where occupant air quality matters without sacrificing system static pressure performance.\u003c\/p\u003e\n\u003cp\u003eThis filter is intended for use in residential furnaces, central air conditioning systems, and air handlers that accept a 1-inch filter slot in a 20x36 nominal opening. It is typically installed by HVAC technicians during routine maintenance or seasonal changeouts, and is also within reach of knowledgeable homeowners performing their own filter service. Sold in a quantity of 10 per order, making it practical for stocking multiple units for scheduled filter replacement intervals.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMERV 11 efficiency rating captures particles as small as 1.0 to 3.0 microns\u003c\/li\u003e\n  \u003cli\u003ePleated media design increases surface area for improved particulate capture and longer service life\u003c\/li\u003e\n  \u003cli\u003eNominal size 20x36x1 inches fits standard 20x36 filter slots\u003c\/li\u003e\n  \u003cli\u003eActual dimensions 19.5 x 35.5 x 0.75 inches for proper fit in nominal 20x36x1 tracks\u003c\/li\u003e\n  \u003cli\u003eSold in a quantity of 10 units per order for maintenance stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement pleated filter for residential and light commercial forced-air HVAC systems with a nominal 20x36x1 inch filter slot.

Before replacing the filter, set the thermostat to the off position to stop airflow through the air handler. Confirm the airflow direction arrow on the filter frame is oriented toward the blower motor and away from the return air duct. MERV 11 filters may increase system static pressure in older or undersized systems, so verify that the system is rated to handle this filtration level before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMERV Rating\u003c\/strong\u003e: MERV 11\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 20x36x1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Size\u003c\/strong\u003e: 19.5 x 35.5 x 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThickness\u003c\/strong\u003e: 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity per Order\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: FILTER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: AF20x36x1-M11\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FILTER","offers":[{"title":"Default Title","offer_id":51716790059314,"sku":"AF20x36x1-M11","price":17.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4f5cc2bafe34b96d3e2d0571e1a0e978_51f21b87-49a3-45ba-85b5-789d8db834c9.jpg?v=1790917555","url":"https:\/\/voomisupply.com\/products\/filter-king-af20x36x1-m11-merv-11-air-filter-20x36x1","provider":"Voomi Supply","version":"1.0","type":"link"}
