With an actual size of 18.5 x 20.5 x 0.75 inches, this filter is hand-cut to the exact dimensions entered at the time of order. The MERV 12 rating means it captures over 90 percent of airborne particles between 3 and 10 microns and 80 to 90 percent of particles between 1 and 3 microns. An activated carbon layer addresses common household odors alongside particulate capture. The reinforced 2-part frame supports consistent airflow and structural integrity over the service life of the filter. HVAC technicians and homeowners install this filter in place of a standard 19x21x1 slot where non-standard dimensions require a custom fit.\u003c\/p\u003e\n\u003cp\u003eThis filter is suited for residential forced-air furnaces and central air conditioning systems with non-standard filter openings. Because dimensions are custom, it is critical to measure the actual opening before ordering. Nordic Pure recommends replacing 1-inch filters every 30 to 90 days depending on the environment, air quality conditions, and system runtime. The carbon media layer makes this filter a practical choice for installations in homes with pets, smokers, or elevated dust and odor concerns. The filter is manufactured in the USA and ships as a set of 6 units per box.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eCustom-made to exact ordered dimensions with an actual size of 18.5 x 20.5 x 0.75 inches\u003c\/li\u003e\n  \u003cli\u003eMERV 12 rating captures lint, dust, pollen, pet dander, mold spores, smoke, bacteria, and viruses\u003c\/li\u003e\n  \u003cli\u003eActivated carbon layer reduces common household odors alongside particulate filtration\u003c\/li\u003e\n  \u003cli\u003eReinforced 2-part frame provides added structural durability and supports balanced airflow\u003c\/li\u003e\n  \u003cli\u003ePackaged as 6 filters per box for multi-change convenience\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 for residential and light-commercial forced-air furnaces and central AC systems requiring a custom 19x21x1 nominal filter size. Verify the actual filter slot dimensions before ordering, as custom sizes are non-returnable. Standard-size filters may not seat correctly in openings that require this custom dimension.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by HVAC technicians or qualified homeowners. Power down or set the thermostat to off before replacing the filter to prevent unfiltered air from being drawn through the system during the swap. 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 actual filter slot opening to the nearest 1\/8 inch before placing an order, as custom sizes cannot be returned.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilter Type\u003c\/strong\u003e: MERV 12 Plus Carbon Pleated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMERV Rating\u003c\/strong\u003e: 12\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 19x21x1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Size\u003c\/strong\u003e: 18.5 x 20.5 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\u003ePackage Weight\u003c\/strong\u003e: 5 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: 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: 848224157403\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: 19x21x1CustomM12+C-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORDIC PURE","offers":[{"title":"Default Title","offer_id":52059489173810,"sku":"19x21x1CustomM12+C-6","price":112.71,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/40183279e2f4016dccc996e0811481b0_1dc78ad5-9108-4962-a481-25b8c06675d5.jpg?v=1790040390","url":"https:\/\/voomisupply.com\/products\/nordic-pure-19x21x1customm12-c-6-merv-12-carbon-filter","provider":"Voomi Supply","version":"1.0","type":"link"}
