Measuring 11.5 x 21 x 0.75 inches actual size, this filter ships as a 6-pack and is hand-cut to those exact dimensions. The electrostatically charged filter media captures over 85% of airborne particles in the 3-10 micron range, including dust, pollen, pet dander, and mold spores. Licensed HVAC technicians and qualified service professionals install this filter during routine maintenance. The moisture-resistant beverage board frame holds its shape in high-humidity return air environments.\u003c\/p\u003e\n\u003cp\u003eThis filter fits residential and commercial forced-air systems that require a custom 11.5 x 21 x 0.75-inch actual-size filter where standard nominal sizes are unavailable. It is well-suited for households with pets or allergy sufferers who need elevated filtration without restricting airflow. Nordic Pure recommends replacement every 1 to 3 months depending on system use, occupancy, and indoor air quality demands. During active home improvement or renovation, more frequent changes are advised due to increased particulate load on the HVAC system.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMERV 10 rated  -  captures over 85% of particles between 3 and 10 microns, including lint, dust, pollen, pet dander, and mold spores\u003c\/li\u003e\n  \u003cli\u003eElectrostatically charged media attracts and holds airborne particles without promoting bacterial or mold growth on the filter surface\u003c\/li\u003e\n  \u003cli\u003eMoisture-resistant beverage board frame maintains structural integrity in typical return-air conditions\u003c\/li\u003e\n  \u003cli\u003eReinforced 2-part frame construction provides added durability while supporting consistent airflow and filtration performance\u003c\/li\u003e\n  \u003cli\u003eCustom-cut to exact dimensions of 11.5 x 21 x 0.75 inches  -  hand-made per order, non-returnable\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 as a custom exact-size replacement filter for residential and commercial forced-air HVAC systems requiring an actual filter size of 11.5 x 21 x 0.75 inches.

Power down or switch the system to the off position at the thermostat before removing the old filter. Confirm airflow direction arrows on the filter frame align with the direction of airflow in the return-air duct or filter cabinet before seating the new filter. Because this is a custom-made product cut to exact dimensions, verify the actual size of the existing filter with a tape measure prior to ordering  -  custom sizes are not eligible for return.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilter Rating\u003c\/strong\u003e: MERV 10\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 Box\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrame Material\u003c\/strong\u003e: Moisture-resistant beverage board\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMedia Charge\u003c\/strong\u003e: Electrostatically charged synthetic media\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 2 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 15 x 26 x 7 inches\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\/2x21x1ExactCustomM10-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORDIC PURE","offers":[{"title":"Default Title","offer_id":51957778546994,"sku":"11_1\/2x21x1ExactCustomM10-6","price":72.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/4b2774cd9a9deadb30ce5073fc7fe774.jpg?v=1789944659","url":"https:\/\/voomisupply.com\/products\/nordic-pure-11_1-2x21x1exactcustomm10-6-merv-10-filter-6pk","provider":"Voomi Supply","version":"1.0","type":"link"}
