Each filter is hand-fabricated to an exact actual size of 20 x 21.5 x 0.75 inches, making it a precision fit for non-standard filter slots that standard off-the-shelf sizes cannot accommodate. The electrostatically charged filter media captures lint, dust, pollen, pet dander, mold spores, and dust mites while maintaining low airflow resistance. The heavy-duty, moisture-resistant beverage board frame provides structural integrity through the full service life of the filter. Sold in a six-pack, this filter carries a MERV 7 efficiency rating as defined by ASHRAE standards, comparable to an MPR 600 rating. Installed by HVAC technicians and knowledgeable homeowners alike.\u003c\/p\u003e\n\u003cp\u003eThis filter is suited for residential homes and office environments where a balance of particulate capture and low static pressure drop is required. The custom dimensions make it appropriate for HVAC systems with non-standard filter cavities where nominal-size filters leave gaps or do not seat correctly. Replacement interval is typically every one to three months, with more frequent changes recommended in households with pets or allergy sufferers. The filter media is engineered to resist bacterial and mold growth on the filter surface itself, helping maintain indoor air quality between change intervals. Each unit in the six-pack is built to the same exact dimensions listed at time of order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMERV 7 rated per ASHRAE standards, capturing 50 to 70 percent of airborne particles between 3 and 10 microns\u003c\/li\u003e\n  \u003cli\u003eExact actual size of 20 x 21.5 x 0.75 inches, custom-fabricated to fit non-standard filter openings\u003c\/li\u003e\n  \u003cli\u003eElectrostatically charged pleated media attracts and retains airborne particles more effectively than fiberglass media\u003c\/li\u003e\n  \u003cli\u003eMoisture-resistant beverage board frame with reinforced two-part construction for durability over the full service interval\u003c\/li\u003e\n  \u003cli\u003eMedia does not promote bacterial or mold growth on the filter surface\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-fit replacement for HVAC systems with a filter cavity accepting a 20 x 21.5 x 0.75-inch filter.

Confirm airflow direction by checking the arrow printed on the filter frame and align it with the direction of airflow toward the air handler or furnace. Because this is a custom-fabricated size, verify the actual cavity dimensions with a tape measure before ordering. Custom filters are not eligible for return, so accurate field measurement is critical prior to purchase.\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 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: 20x21_1\/2x1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Size\u003c\/strong\u003e: 20 x 21.5 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\u003eCountry of Origin\u003c\/strong\u003e: USA\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Dimensions\u003c\/strong\u003e: 21 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: 20x21_1\/2x1ExactCustomM7-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORDIC PURE","offers":[{"title":"Default Title","offer_id":51993040355634,"sku":"20x21_1\/2x1ExactCustomM7-6","price":78.57,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b8bdff14e88b596e98d4712086499c4a_63f095bf-68d9-4b5c-b222-ebcb02d7cca1.jpg?v=1789990789","url":"https:\/\/voomisupply.com\/products\/nordic-pure-20x21_1-2x1exactcustomm7-6-merv-7-filter-6-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
