With a nominal size of 16x25x4 inches and an actual size of 15.5 x 24.5 x 3.75 inches, this 4-inch depth filter delivers enhanced particulate capture compared to standard 1-inch filters. MERV 13 filtration captures fine particles including dust, pollen, mold spores, pet dander, and fine smoke particles, making it suitable for systems where air quality is a priority. Licensed HVAC technicians and property maintenance professionals typically specify this filter tier for residential air handlers and forced-air furnaces.\u003c\/p\u003e\n\u003cp\u003eThis filter fits air handlers, furnaces, and central HVAC systems that accept a 16x25x4 nominal filter slot. The 4-inch depth provides extended media surface area, which supports longer service intervals compared to 1-inch or 2-inch alternatives. It is commonly installed in whole-home filter cabinets and media filter housings designed for 4-inch depth cartridges. Ten filters are included per order quantity, supporting multi-unit service or scheduled replacement programs.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMERV 13 rated pleated media for high-efficiency particulate filtration\u003c\/li\u003e\n  \u003cli\u003eNominal size 16x25x4 inches fits standard 4-inch filter cabinets\u003c\/li\u003e\n  \u003cli\u003eActual size 15.5 x 24.5 x 3.75 inches for proper fit in media housings\u003c\/li\u003e\n  \u003cli\u003e4-inch depth increases media surface area and extends replacement intervals\u003c\/li\u003e\n  \u003cli\u003ePleated construction supports airflow while maintaining filtration efficiency\u003c\/li\u003e\n  \u003cli\u003eSold in a quantity of 10 per order, suitable for maintenance stock\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for residential and light commercial HVAC systems and air handlers that accept a 16x25x4 nominal, 4-inch depth pleated media filter cartridge.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eHVAC technicians and qualified service professionals should power down the air handler or furnace at the disconnect before servicing the filter. Verify the actual filter slot dimensions against the actual filter size of 15.5 x 24.5 x 3.75 inches before installation to confirm proper seating. Install the filter with the airflow arrow on the frame pointing toward the blower. Replace at manufacturer-recommended intervals or when pressure drop across the filter indicates loading, typically more frequent in high-occupancy or high-particulate environments.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMERV Rating\u003c\/strong\u003e: MERV 13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 16 x 25 x 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Size\u003c\/strong\u003e: 15.5 x 24.5 x 3.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilter Thickness\u003c\/strong\u003e: 4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity per Order\u003c\/strong\u003e: 10 filters\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: AF16x25x4-M13\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FILTER","offers":[{"title":"Default Title","offer_id":51716763648306,"sku":"AF16x25x4-M13","price":20.78,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ded7b7b395536dd1b22964e7663d2b19_2b585f00-5ab7-4c2a-82e8-b55f1200a080.jpg?v=1790917332","url":"https:\/\/voomisupply.com\/products\/filter-king-af16x25x4-m13-merv-13-air-filter-16x25x4","provider":"Voomi Supply","version":"1.0","type":"link"}
