The pleated media construction increases the effective surface area compared to flat fiberglass media, which improves particulate capture and extends the interval between filter changes. This filter is installed by HVAC technicians and qualified service professionals as part of routine preventive maintenance on forced-air heating and cooling systems.\u003c\/p\u003e\u003cp\u003eThis filter fits standard 12 x 25 x 1 inch filter slots found in air handlers, furnaces, and return-air grilles across a wide range of residential and light commercial installations. It is a practical replacement choice for any system that accepts a nominal 12 x 25 x 1 inch filter, including upflow, downflow, and horizontal-flow units. Pleated filters of this size are among the most common panel filter dimensions used in North American forced-air systems.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePleated media design increases surface area for improved particle capture relative to flat panel filters\u003c\/li\u003e\n\u003cli\u003eNominal size of 12 x 25 x 1 inch fits a wide range of standard HVAC filter slots\u003c\/li\u003e\n\u003cli\u003eExtended service interval between filter changes compared to fiberglass panel filters\u003c\/li\u003e\n\u003cli\u003eDrop-in installation with no tools required in properly sized filter tracks\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement pleated panel filter for residential and light commercial forced-air HVAC systems accepting a nominal 12 x 25 x 1 inch filter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003ePleated air filters are installed by HVAC technicians as part of routine system maintenance. Always power down the air handler or furnace at the disconnect or breaker before removing or installing a filter. Confirm airflow direction before inserting the filter, as the arrow printed on the filter frame must point toward the blower and away from the return air stream. Follow local mechanical codes and equipment manufacturer maintenance schedules for recommended filter change intervals.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Type\u003c\/strong\u003e: Pleated Panel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Length\u003c\/strong\u003e: 25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Width\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Depth\u003c\/strong\u003e: 1 inch\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: P411225\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KOCH FILTER","offers":[{"title":"Default Title","offer_id":51344125493554,"sku":"P411225","price":20.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555295.jpg?v=1782030015","url":"https:\/\/voomisupply.com\/products\/koch-filter-p411225-pleated-air-filter-12x25x1","provider":"Voomi Supply","version":"1.0","type":"link"}
