It is designed for residential and light-commercial HVAC systems, including forced-air furnaces and central air conditioning units. The filter captures over 85% of airborne particles between 3 and 10 microns, including dust, pollen, pet dander, mold spores, and odors. The activated carbon layer addresses gaseous contaminants that standard pleated filters miss. The actual dimensions are 20.5 x 26.25 x 0.75 inches, which differ from the nominal 21x27x1 listing, as is standard across the HVAC filter industry. Licensed HVAC technicians and qualified DIYers install this filter at the return-air grille or air handler.\u003c\/p\u003e\u003cp\u003eThis filter is suited for residential forced-air systems requiring a 21x27x1 nominal filter slot. The MERV 10 rating balances filtration efficiency with low airflow resistance, making it appropriate for standard residential air handlers without high-static-pressure concerns. The reinforced 2-part frame provides structural stability across the full service interval. Nordic Pure recommends replacing 1-inch filters every 30 to 90 days, depending on household conditions such as pets, dust levels, and occupancy. This product is custom-made to the exact listed dimensions and is not eligible for return.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMERV 10 rating captures over 85% of particles between 3 and 10 microns, including lint, dust, pollen, pet dander, mold spores, and odors\u003c\/li\u003e\n\u003cli\u003eActivated carbon layer reduces gaseous contaminants and household odors that standard pleated media does not address\u003c\/li\u003e\n\u003cli\u003eReinforced 2-part frame provides added structural durability and supports consistent airflow throughout the filter life\u003c\/li\u003e\n\u003cli\u003eCustom-made to exact nominal dimensions of 21x27x1 inches; actual size is 20.5 x 26.25 x 0.75 inches\u003c\/li\u003e\n\u003cli\u003eSold as a 6-pack for convenient bulk replacement stocking\u003c\/li\u003e\n\u003cli\u003eMade in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCustom-made as an OEM-style replacement for residential and light-commercial forced-air furnace and air conditioning systems requiring a 21x27x1 nominal filter size.

Power down the air handler or furnace at the disconnect or breaker before removing the old filter and inserting the replacement. Confirm airflow direction arrows on the filter frame align with the direction of airflow toward the blower. Because this is a custom-cut product, measure the existing filter or the filter slot to the nearest fraction of an inch before ordering to ensure proper fit.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFilter Type\u003c\/strong\u003e: MERV 10 Plus Carbon Pleated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMERV Rating\u003c\/strong\u003e: 10\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 21x27x1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActual Size\u003c\/strong\u003e: 20.5 x 26.25 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\u003eWeight\u003c\/strong\u003e: 7 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBox Dimensions\u003c\/strong\u003e: 26 x 32 x 7 inches\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: 848224156239\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 21x27x1CustomM10+C-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORDIC PURE","offers":[{"title":"Default Title","offer_id":52058073301298,"sku":"21x27x1CustomM10+C-6","price":141.23,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/101b1300033b35987e698aad28b6d8a2_bd4f90c6-d1f9-437f-a39b-389cfe946766.jpg?v=1790039396","url":"https:\/\/voomisupply.com\/products\/nordic-pure-21x27x1customm10-c-6-merv-10-carbon-filter","provider":"Voomi Supply","version":"1.0","type":"link"}
