It is designed for residential and commercial HVAC systems that require a nominal 20x21x1 filter with an actual size of 20 x 21 x 0.75 inches. The electrostatically charged filter media captures over 90% of airborne particles between 1 and 10 microns, and 75% to 95% of particles between 0.3 and 1 microns. Targeted contaminants include lint, dust, pollen, pet dander, mold spores, smoke, bacteria, virus carriers, and smog. The frame is constructed from a heavy-duty, moisture-resistant beverage board and is manufactured in the USA.\u003c\/p\u003e\n\u003cp\u003eThis filter is suited for residential homes and light commercial spaces where high-efficiency air filtration is a priority. It fits HVAC systems  -  including newer high-efficiency units  -  that are rated to handle MERV 14 filters and above. Because MERV 14 filtration increases airflow restriction compared to lower-rated filters, the system must be rated to support it. These filters are custom-made to the exact nominal dimensions of 20 x 21 x 1 inches, making them appropriate for units that require a precise fit rather than a standard off-the-shelf size. Replacement is recommended every 1 to 3 months, with more frequent changes in homes with pets or allergy sufferers.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMERV 14 rating captures over 90% of particles from 1 to 10 microns and 75% to 95% of particles from 0.3 to 1 microns\u003c\/li\u003e\n  \u003cli\u003eElectrostatically charged media attracts airborne particles and does not promote bacterial or mold growth on the filter surface\u003c\/li\u003e\n  \u003cli\u003eHeavy-duty, moisture-resistant beverage board frame with reinforced 2-part construction for added durability\u003c\/li\u003e\n  \u003cli\u003eCustom-cut to exact nominal dimensions  -  hand-made per order using cut-down or combined frames; tape may be used depending on size\u003c\/li\u003e\n  \u003cli\u003eComparable to filters rated MPR 2800 on manufacturer-specific rating scales\u003c\/li\u003e\n  \u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCustom-made as an exact-fit replacement for HVAC systems requiring a nominal 20x21x1 filter.

Verify the actual opening dimensions of the filter slot before ordering, as this is a non-returnable custom size.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by HVAC technicians or qualified service personnel. Always shut down the HVAC system at the thermostat and disconnect power at the air handler before removing or installing the filter. Confirm the actual slot dimensions with a tape measure before ordering, as custom-cut filters are not eligible for return. Check the filter monthly and replace every 1 to 3 months, or more frequently in high-traffic or high-allergen environments.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilter Rating\u003c\/strong\u003e: MERV 14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 20 x 21 x 1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Size\u003c\/strong\u003e: 20 x 21 x 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity per Box\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 8 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBox Width\u003c\/strong\u003e: 21 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: 11 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFrame Material\u003c\/strong\u003e: Heavy-duty moisture-resistant beverage board\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCountry of Origin\u003c\/strong\u003e: USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 848224103820\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: 20x21x1ExactCustomM14-12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORDIC PURE","offers":[{"title":"Default Title","offer_id":51994134217010,"sku":"20x21x1ExactCustomM14-12","price":320.49,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0ad3e8229751cb69caa9121104b8be6e_6ca07b10-21ec-48bc-9b9f-b4450847651f.jpg?v=1789991678","url":"https:\/\/voomisupply.com\/products\/nordic-pure-20x21x1exactcustomm14-12-merv-14-filter-12pk","provider":"Voomi Supply","version":"1.0","type":"link"}
