Sold in a 12-pack, this filter is designed for HVAC professionals and facilities managers who need precise sizing that standard off-the-shelf filters cannot provide. The electrostatic pleated media captures over 90% of airborne particles between 1 and 10 microns, and 75% to 95% of particles between 0.3 and 1 micron, including bacteria, mold spores, smoke, and virus carriers. The heavy-duty, moisture-resistant beverage board frame supports consistent airflow and structural integrity throughout the filter life.\u003c\/p\u003e\n\u003cp\u003eThis filter is suited for residential and light commercial HVAC systems requiring high-efficiency filtration. MERV 14 performance is comparable to MPR 2800-rated filters. Because MERV 14 restricts airflow more than lower-rated filters, the HVAC system must be rated to handle MERV 14 or higher before installation. This rating makes the filter well-suited for newer high-efficiency systems, environments with allergy or asthma concerns, and spaces where airborne pathogen reduction is a priority. Nordic Pure recommends replacing filters every 1 to 3 months, with more frequent changes in homes with pets or occupants sensitive to allergens. The 12-pack format supports a consistent replacement schedule.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMERV 14 rated: captures over 90% of particles from 1 to 10 microns and 75% to 95% of particles from 0.3 to 1 micron\u003c\/li\u003e\n  \u003cli\u003eExact actual size 17 x 21 x 0.75 inches, custom-cut to fit non-standard openings\u003c\/li\u003e\n  \u003cli\u003eElectrostatically charged pleated media attracts and holds fine particles including smoke, bacteria, and virus carriers\u003c\/li\u003e\n  \u003cli\u003eMoisture-resistant beverage board frame with reinforced 2-part construction for durability\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-size replacement filter for residential and light commercial HVAC, furnace, and air conditioning systems with a 17 x 21 x 1 nominal filter opening. The HVAC system must be rated to operate with MERV 14 or higher filters. Verify actual filter slot dimensions before ordering, as custom sizes are non-returnable.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by HVAC technicians or qualified service personnel. Power down or set the thermostat to the off position before removing the existing filter to prevent unfiltered air from circulating through the air handler. Confirm the airflow direction arrow on the filter frame aligns with the direction of airflow toward the blower before seating the filter. Because this is a custom-cut size, measure the actual filter slot opening carefully before ordering, as these filters are hand-made to specified dimensions and are not eligible for return.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilter Rating\u003c\/strong\u003e: MERV 14\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 17 x 21 x 1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Size\u003c\/strong\u003e: 17 x 21 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\u003eFrame Material\u003c\/strong\u003e: Moisture-resistant beverage board\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMedia Charge\u003c\/strong\u003e: Electrostatic\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: 848224103738\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: 17x21x1ExactCustomM14-12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORDIC PURE","offers":[{"title":"Default Title","offer_id":51961568231730,"sku":"17x21x1ExactCustomM14-12","price":300.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0ad3e8229751cb69caa9121104b8be6e.jpg?v=1789947085","url":"https:\/\/voomisupply.com\/products\/nordic-pure-17x21x1exactcustomm14-12-merv-14-filter-12-pack","provider":"Voomi Supply","version":"1.0","type":"link"}
