It is constructed from electrostatically charged synthetic media that captures a broad range of airborne particulates, including particles as small as 0.3 microns. At MERV 13, the filter captures over 90% of particles between 1 and 10 microns and 50% to 70% of particles between 0.3 and 1 micron. The carbon layer provides additional odor reduction. The nominal size is 16x21x1 with an actual size of 15.5 x 20.5 x 0.75 inches. Licensed HVAC technicians and knowledgeable DIYers install this filter in forced-air heating and cooling systems.\u003c\/p\u003e\n\u003cp\u003eThis filter is designed for residential and light-commercial forced-air HVAC systems where a standard size does not fit the filter slot. Because it is custom-made to the exact nominal dimensions listed, the actual dimensions are 15.5 x 20.5 x 0.75 inches. The 12-pack format suits service contractors maintaining multiple units or homeowners on a routine replacement schedule. Nordic Pure recommends replacing the filter every 30 to 90 days depending on indoor and outdoor air quality conditions. The reinforced 2-part frame supports consistent airflow and structural integrity over the full service life of the filter.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMERV 13 rating captures over 90% of airborne particles between 1 and 10 microns, including dust, pollen, mold spores, pet dander, smoke, bacteria, and viruses\u003c\/li\u003e\n  \u003cli\u003eActivated carbon layer reduces common household odors in the airstream\u003c\/li\u003e\n  \u003cli\u003eElectrostatically charged synthetic media attracts and holds fine particulates without excessive airflow restriction\u003c\/li\u003e\n  \u003cli\u003eReinforced 2-part frame provides added structural durability compared to single-frame designs\u003c\/li\u003e\n  \u003cli\u003eCustom-cut to nominal size 16x21x1 with actual dimensions of 15.5 x 20.5 x 0.75 inches\u003c\/li\u003e\n  \u003cli\u003eMade in the USA; sold as a 12-pack\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eCustom-made to the nominal size 16x21x1.

Power down the air handler or furnace at the disconnect before removing the old filter. Confirm airflow direction and install the new filter with the arrow on the frame pointing toward the blower. Measure the actual filter slot opening before ordering a custom size to ensure proper fit; the actual filter dimensions should be within 0.125 inches of the slot opening.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilter Type\u003c\/strong\u003e: MERV 13 Plus Carbon\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMERV Rating\u003c\/strong\u003e: 13\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 16x21x1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Size\u003c\/strong\u003e: 15.5 x 20.5 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 Dimensions\u003c\/strong\u003e: 21 x 26 x 11 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: 848224114529\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: 16x21x1CustomM13+C-12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORDIC PURE","offers":[{"title":"Default Title","offer_id":52112446259506,"sku":"16x21x1CustomM13+C-12","price":325.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1b88bae7214f3e3c314a1cf76b08678f_93236634-9c66-4ab4-b41b-107d46c6e125.jpg?v=1790077674","url":"https:\/\/voomisupply.com\/products\/nordic-pure-16x21x1customm13-c-12-merv-13-carbon-filter","provider":"Voomi Supply","version":"1.0","type":"link"}
