Built from electrostatically charged synthetic media, it captures airborne particulates down to 0.3 microns while the activated carbon layer targets odors and volatile compounds. The filter measures an actual 13 x 21 x 0.75 inches, making it a precision-fit replacement for duct openings that do not accept a standard nominal size. HVAC technicians and homeowners install these in gas furnaces, air handlers, and central AC systems requiring exact-dimension filtration. This pack contains 6 filters.\u003c\/p\u003e\n\u003cp\u003eThis filter is suited for residential and light commercial HVAC applications where a non-standard slot width or length prevents the use of off-the-shelf nominal sizes. The exact 13 x 21 x 0.75 inch actual dimension ensures a proper seal against filter bypass. Typical install locations include horizontal or vertical filter racks in forced-air gas furnace systems and air handler cabinets. MERV 13 plus carbon performance makes it appropriate for environments with allergy concerns, pet dander, smoke, or odor complaints. Six filters per box supports a multi-month maintenance cycle when changed every 30 to 90 days.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMERV 13 rated media captures over 90% of particles between 1 and 10 microns and 50% to 70% of particles between 0.3 and 1 micron, including pollen, mold spores, bacteria, smoke, and fine dust\u003c\/li\u003e\n  \u003cli\u003eActivated carbon layer reduces odors and gaseous contaminants from the airstream\u003c\/li\u003e\n  \u003cli\u003eElectrostatically charged synthetic media attracts and holds particulates without sacrificing airflow resistance\u003c\/li\u003e\n  \u003cli\u003eReinforced 2-part frame provides added structural durability compared to single-frame standard filters\u003c\/li\u003e\n  \u003cli\u003eCustom exact-cut construction to actual size 13 x 21 x 0.75 inches, eliminating filter bypass common with loose-fitting nominal sizes\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-made to exact dimensions for HVAC filter slots requiring an actual size of 13 x 21 x 0.75 inches. Verify your current filter slot measurement before ordering. Custom sizes are non-returnable; a tape measure check of the existing filter opening is strongly recommended prior to purchase.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by HVAC technicians or qualified homeowners. Always shut down the furnace or air handler at the disconnect or thermostat before removing the existing filter. Confirm airflow direction arrow on the filter frame aligns with the direction of airflow toward the blower. Replace every 30 to 90 days depending on indoor air quality conditions, occupancy, and system runtime. Because this is a custom-cut filter, measure the actual slot opening before ordering a replacement.\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: 13x21x1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Size\u003c\/strong\u003e: 13 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\u003eWeight\u003c\/strong\u003e: 4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBox Width\u003c\/strong\u003e: 15 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\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: 13x21x1ExactCustomM13+C-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORDIC PURE","offers":[{"title":"Default Title","offer_id":52123688010034,"sku":"13x21x1ExactCustomM13+C-6","price":149.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b4260f71d995777c5733963f396df69_7acd11e8-f6f0-4647-8df3-61f871cf5438.jpg?v=1790086290","url":"https:\/\/voomisupply.com\/products\/nordic-pure-13x21x1exactcustomm13-c-6-merv-13-filter-6pk","provider":"Voomi Supply","version":"1.0","type":"link"}
