The increased media depth expands available surface area, which raises dust-holding capacity and extends service intervals between changeouts. The pleated construction supports consistent airflow resistance across the filter face, helping the air handler maintain designed static pressure. Licensed HVAC technicians and knowledgeable service technicians install this filter during routine maintenance or system tune-ups.\u003c\/p\u003e\n\u003cp\u003eThis filter fits forced-air heating and cooling systems with a 15 x 25 x 2 inch filter slot. The 2-inch depth makes it suited for applications where longer service life is preferred over frequent 1-inch filter replacements, including systems serving high-traffic residential spaces, small commercial offices, or any environment with moderate airborne particulate loads. Confirm the filter cabinet or rack is rated for 2-inch media before installation.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e2-inch media depth increases dust-holding capacity versus standard 1-inch filters\u003c\/li\u003e\n  \u003cli\u003ePleated construction maximizes filtration surface area within a compact frame\u003c\/li\u003e\n  \u003cli\u003eSupports proper airflow and static pressure in forced-air HVAC systems\u003c\/li\u003e\n  \u003cli\u003eExtended service intervals reduce frequency of scheduled filter changes\u003c\/li\u003e\n  \u003cli\u003eNominal size 15 x 25 x 2 inches fits compatible filter tracks and cabinets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement pleated air filter for forced-air HVAC systems with a 15 x 25 x 2 inch filter opening.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePower down the air handler or furnace at the disconnect or thermostat before servicing the filter. Confirm the filter cabinet is designed to accept 2-inch media, as forcing an oversized filter into a 1-inch rack restricts airflow and can damage the blower. Slide the filter into the track with the airflow arrow on the frame pointing toward the blower. Follow local mechanical codes and the equipment manufacturer service instructions for recommended changeout intervals.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilter Depth\u003c\/strong\u003e: 2 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilter Width\u003c\/strong\u003e: 15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilter Length\u003c\/strong\u003e: 25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilter Type\u003c\/strong\u003e: Pleated\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: KOCH FILTER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: P421525\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KOCH FILTER","offers":[{"title":"Default Title","offer_id":51342753661234,"sku":"P421525","price":23.38,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310554691.png?v=1782005627","url":"https:\/\/voomisupply.com\/products\/koch-filter-p421525-pleated-air-filter-15x25x2","provider":"Voomi Supply","version":"1.0","type":"link"}
