The pleated media construction maximizes surface area within the filter frame, which improves dust holding capacity and extends service intervals without sacrificing airflow. This filter measures 12 inches by 16 inches by 2 inches and is installed in the return-air side of forced-air heating and cooling systems. HVAC technicians and service pros handling preventive maintenance or filter changeouts will find this a straightforward drop-in replacement where a 2-inch slot is present.\u003c\/p\u003e\u003cp\u003eThis filter is suited for residential forced-air furnaces, central air handlers, and heat pumps that accept a 2-inch filter in a 12-by-16-inch opening. The deeper media bed is particularly appropriate for applications where longer filter life between service visits is a priority, such as occupied residences with consistent particulate loads or light commercial spaces running extended duty cycles. Proper sizing of the filter slot should be confirmed before installation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e2-inch depth provides greater media surface area than standard 1-inch filters, supporting longer service intervals\u003c\/li\u003e\n\u003cli\u003ePleated media construction increases dust holding capacity and maintains airflow efficiency\u003c\/li\u003e\n\u003cli\u003eNominal dimensions of 12 x 16 x 2 inches for compatibility with standard return-air filter tracks and cabinets\u003c\/li\u003e\n\u003cli\u003eDesigned for forced-air HVAC applications including furnaces and central air handlers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a replacement pleated air filter for residential and light commercial forced-air HVAC systems accepting a nominal 12-inch by 16-inch by 2-inch filter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or qualified service professional. Always shut down the air handler or furnace at the disconnect or thermostat before removing or installing filters. Confirm airflow direction before seating the filter — the arrow printed on the filter frame must point toward the blower, not the return duct. Inspect the filter housing gasket or track for damage that could allow bypass air around the filter media.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Length\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Width\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Depth\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMedia Type\u003c\/strong\u003e: Pleated\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KOCH FILTER\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: P421216\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KOCH FILTER","offers":[{"title":"Default Title","offer_id":51345642160434,"sku":"P421216","price":22.63,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554658.jpg?v=1782061360","url":"https:\/\/voomisupply.com\/products\/koch-filter-p421216-pleated-air-filter-12x16x2","provider":"Voomi Supply","version":"1.0","type":"link"}
