Sold in a 6-pack, each filter measures 21 x 21 x 0.75 inches actual size and is built to exact dimensions for a precise fit in forced-air furnace and air conditioning applications. The electrostatically charged filter media captures over 90% of airborne particles between 1 and 10 microns, and 50% to 70% of particles between 0.3 and 1 microns. MERV 13 efficiency is equivalent to MPR 2200-2400 ratings used by some manufacturers. The heavy-duty beverage board frame is moisture resistant and rated for regular replacement cycles of one to three months depending on environmental conditions.\u003c\/p\u003e\n\u003cp\u003eThese filters are suited for residential homes, offices, and light commercial spaces where occupants face allergen concerns such as pet dander, pollen, mold spores, smoke, bacteria, and virus carriers. MERV 13 filtration at this level is commonly specified in HVAC systems that require enhanced indoor air quality without extreme pressure drop. Custom sizing makes these filters appropriate for non-standard filter openings where off-the-shelf nominal sizes do not fit correctly. HVAC technicians and facility maintenance personnel installing these in existing duct systems should verify the actual opening dimensions before ordering, as custom sizes are built to the exact measurements provided at time of order.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMERV 13 rated filtration captures particles as small as 0.3 microns including bacteria, smoke, and virus carriers\u003c\/li\u003e\n  \u003cli\u003eElectrostatically charged pleated media provides higher particle capture efficiency than standard fiberglass filters\u003c\/li\u003e\n  \u003cli\u003eMoisture-resistant beverage board frame with reinforced 2-part construction for durability and consistent airflow support\u003c\/li\u003e\n  \u003cli\u003eActual size 21 x 21 x 0.75 inches  -  custom cut to exact dimensions for non-standard filter openings\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\u003eCustom-sized OEM-style replacement filter for residential and commercial forced-air furnace and air conditioning systems requiring a 21 x 21 x 0.75 inch actual-size filter opening. Measure the existing filter or the filter slot before ordering  -  custom sizes are not eligible for return.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eHVAC technicians and knowledgeable DIYers should power down the furnace or air handler at the disconnect before replacing the filter. Confirm airflow direction marked on the filter frame aligns with the direction of airflow in the duct or cabinet. Because this is a custom-fabricated size, verify actual slot dimensions with a tape measure prior to ordering  -  nominal size printed on an existing filter often differs from actual size. Replace every one to three months, or more frequently in high-dust environments or where occupants have respiratory sensitivities.\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 Pleated\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: 21x21x1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Size\u003c\/strong\u003e: 21 x 21 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\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  \u003cli\u003e\n\u003cstrong\u003ePackage Weight\u003c\/strong\u003e: 7 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Width\u003c\/strong\u003e: 26 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Height\u003c\/strong\u003e: 26 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Depth\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUPC\u003c\/strong\u003e: 848224098966\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: 21x21x1ExactCustomM13-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORDIC PURE","offers":[{"title":"Default Title","offer_id":52013090406706,"sku":"21x21x1ExactCustomM13-6","price":152.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b571d721d0ca365cf1fa16cc3e5be372_17d1e036-7657-4606-aa3f-248cd7905dfa.jpg?v=1790005940","url":"https:\/\/voomisupply.com\/products\/nordic-pure-21x21x1exactcustomm13-6-merv-13-filter-6pk","provider":"Voomi Supply","version":"1.0","type":"link"}
