With an actual size of 8.75 x 18 x 0.75 inches, this filter is built to exact dimensions and ships as a 6-pack. The electrostatically charged filter media captures over 90% of airborne particles in the 3-10 micron range and 80-90% in the 1-3 micron range, targeting lint, dust, pollen, pet dander, mold spores, smoke, bacteria, and virus carriers. The moisture-resistant beverage board frame provides structural support without promoting mold or bacterial growth on the media itself. Licensed HVAC technicians and experienced DIYers install these as direct replacements in standard filter slots.\u003c\/p\u003e\n\u003cp\u003eThis filter is suited for residential homes and commercial office environments where occupants deal with allergies, pet dander, or elevated particulate concerns. MERV 12 efficiency is comparable to filters rated MPR 1500-1900 on proprietary scales. The MERV rating system is standardized by ASHRAE, making cross-brand efficiency comparisons straightforward. Nordic Pure recommends replacing this filter every 1-3 months under normal conditions. Households with pets or allergy sufferers should replace more frequently. This custom size is manufactured by cutting down or combining standard filter frames and may be reinforced with tape at seams depending on the final dimensions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMERV 12 efficiency captures over 90% of particles at 3-10 microns and 80-90% at 1-3 microns\u003c\/li\u003e\n  \u003cli\u003eElectrostatically charged pleated media attracts and holds fine airborne particles\u003c\/li\u003e\n  \u003cli\u003eMoisture-resistant beverage board frame resists warping and structural failure in humid conditions\u003c\/li\u003e\n  \u003cli\u003eReinforced 2-part frame construction adds durability for custom-cut sizes\u003c\/li\u003e\n  \u003cli\u003eCustom exact-cut dimensions to fit non-standard filter slots where nominal sizes do not apply\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-cut to the exact actual size of 8.75 x 18 x 0.75 inches for HVAC systems requiring a non-standard filter slot. Measure the existing filter opening before ordering, as this size is non-returnable and made to order. Confirm actual slot dimensions rather than relying on the nominal size printed on a current filter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003ePower down or set the thermostat to off before removing the old filter to prevent unfiltered air from circulating through the air handler during the swap. Slide the new filter into the filter slot with the airflow arrow on the frame pointing toward the blower and away from the return air duct. Confirm the filter seats flush with no gaps at the frame edges, as bypass air around an ill-fitting custom filter reduces filtration efficiency. Note the installation date and replace on a 1-3 month schedule, or more frequently in high-particulate or high-occupancy environments.\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 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: 8-3\/4 x 18 x 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Size\u003c\/strong\u003e: 8.75 x 18 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: 2.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBox Dimensions\u003c\/strong\u003e: 21 x 16 x 7 inches\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\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: 8_3\/4x18x1ExactCustomM12-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORDIC PURE","offers":[{"title":"Default Title","offer_id":51959084384562,"sku":"8_3\/4x18x1ExactCustomM12-6","price":60.55,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d66f2f786b1ca9985b67fb4ffaacb9f2_6864b565-88ea-44db-87ac-7548ce3b6c21.jpg?v=1789945459","url":"https:\/\/voomisupply.com\/products\/nordic-pure-8_3-4x18x1exactcustomm12-6-merv-12-filter-6-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
