It combines mechanical particulate filtration with an activated carbon layer to capture airborne particles and reduce common household odors in a single pass. This filter is hand-fabricated to order and ships as a 6-pack. Licensed HVAC technicians and experienced DIYers install this filter in residential forced-air systems where a non-standard opening makes off-the-shelf sizes unsuitable. The reinforced 2-part frame supports consistent airflow and structural integrity throughout the filter's service life.\u003c\/p\u003e\n\u003cp\u003eThis filter is designed for residential HVAC systems  -  gas furnaces, heat pumps, and central air conditioning air handlers  -  that require a custom nominal size of 11.5 x 21 x 1 inch. It is built to exact measurements rather than nominal industry sizing, so the actual filter dimensions are 11.5 x 21 x 0.75 inches. Installers should verify the actual opening size with a tape measure before ordering, confirming width and length are within 0.125 inches of 11.5 x 21. The 1-inch depth suits standard single-slot filter tracks. Recommended replacement interval is every 30 to 90 days depending on environment and air quality conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMERV 7 rated  -  captures 50 to 70 percent of airborne particles between 3 and 10 microns, including dust, lint, pollen, pet dander, mold spores, and odors\u003c\/li\u003e\n  \u003cli\u003eActivated carbon layer reduces common airborne odors without significantly increasing static pressure drop\u003c\/li\u003e\n  \u003cli\u003eCustom exact-cut to 11.5 x 21 x 0.75 inches  -  hand-fabricated per order to fit non-standard filter openings\u003c\/li\u003e\n  \u003cli\u003eReinforced 2-part frame provides added structural durability and supports balanced airflow over the full service interval\u003c\/li\u003e\n  \u003cli\u003eSold as a 6-pack to reduce reorder frequency\u003c\/li\u003e\n  \u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for residential forced-air HVAC systems requiring a custom filter size with a nominal dimension of 11.5 x 21 x 1 inch. Measure the actual filter slot before ordering  -  custom sizes are non-returnable and built specifically to the dimensions entered at time of purchase.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eA licensed HVAC technician or qualified installer should power down the air handler or furnace at the disconnect or breaker before replacing the filter. Confirm airflow direction arrows on the filter frame align with the direction of airflow toward the blower. Because this is a custom-sized filter with an actual depth of 0.75 inches, verify the track depth accommodates the filter before installation. Custom filters are not eligible for return, so measurement accuracy before ordering is critical.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilter Type\u003c\/strong\u003e: MERV 7 Plus Carbon pleated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMERV Rating\u003c\/strong\u003e: 7\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 11.5 x 21 x 1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Size\u003c\/strong\u003e: 11.5 x 21 x 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBox Width\u003c\/strong\u003e: 15 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBox Height\u003c\/strong\u003e: 26 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBox Depth\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: USA\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: NORDIC PURE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 11_1\/2x21x1ExactCustomM7+C-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORDIC PURE","offers":[{"title":"Default Title","offer_id":52034150433074,"sku":"11_1\/2x21x1ExactCustomM7+C-6","price":88.52,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/22407e7d058256b6ce95849ba8756844_fc037e2d-ada7-42ab-a4d3-99240f0e592f.jpg?v=1790022103","url":"https:\/\/voomisupply.com\/products\/nordic-pure-11_1-2x21x1exactcustomm7-c-6-merv-7-carbon-filter","provider":"Voomi Supply","version":"1.0","type":"link"}
