Built to exact dimensions of 17.5 x 21 x 0.75 inches, this filter combines high-efficiency mechanical filtration with an activated carbon layer to capture both particulate matter and odors. It is custom-manufactured to match non-standard filter openings and is installed by HVAC technicians or experienced homeowners who have confirmed their exact filter cavity measurements before ordering. The pack contains 6 filters.\u003c\/p\u003e\n\u003cp\u003eThis filter fits non-standard or custom-dimension filter slots in residential and light commercial forced-air HVAC systems where standard nominal sizes do not match the actual opening. Because this product is hand-cut to the exact dimensions entered at time of order, it is intended for installations where the actual filter cavity measures 17.5 x 21 x 0.75 inches. Installers should verify the actual opening with a tape measure before ordering, as the actual size of most filter slots differs from the nominal label by a fraction of an inch. Recommended replacement interval for 1-inch filters is every 30 to 90 days depending on air quality and household conditions.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMERV 13 filtration captures over 90% of airborne particles between 1 and 10 microns, and 50% to 70% of particles between 0.3 and 1 micron, including dust, pollen, pet dander, mold spores, smoke, bacteria, and viruses\u003c\/li\u003e\n  \u003cli\u003eActivated carbon layer adsorbs household odors including smoke and smog-related compounds\u003c\/li\u003e\n  \u003cli\u003eCustom-cut to exact dimensions of 17.5 x 21 x 0.75 inches for non-standard filter openings\u003c\/li\u003e\n  \u003cli\u003eReinforced 2-part frame construction provides structural support and consistent airflow across the filter face\u003c\/li\u003e\n  \u003cli\u003eSold in a 6-pack; each filter has a recommended service life of 30 to 90 days for 1-inch depth installations\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 fit HVAC filter slots with an actual opening of 17.5 x 21 x 0.75 inches.

Confirm airflow direction arrows on the filter frame are oriented toward the blower, not the return air duct. Because this is a custom-cut product, verify actual cavity dimensions to within 0.125 inches before ordering. Standard industry guidance calls for replacing 1-inch filters every 30 to 90 days; environments with high dust loads, pets, or construction activity will shorten service intervals.\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: 17.5 x 21 x 1 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eActual Size\u003c\/strong\u003e: 17.5 x 21 x 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eQuantity per Pack\u003c\/strong\u003e: 6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 5 pounds\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: 848224158455\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: 17_1\/2x21x1ExactCustomM13+C-6\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NORDIC PURE","offers":[{"title":"Default Title","offer_id":52068457316658,"sku":"17_1\/2x21x1ExactCustomM13+C-6","price":171.37,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0b4260f71d995777c5733963f396df69_8e070d5f-d3a8-48a7-a349-4f20e028c690.jpg?v=1790047097","url":"https:\/\/voomisupply.com\/products\/nordic-pure-17_1-2x21x1exactcustomm13-c-6-merv-13-filter","provider":"Voomi Supply","version":"1.0","type":"link"}
