It generates an electrostatic charge as air passes through a maze of static-prone synthetic fibers, attracting and holding airborne particulates until the filter is washed and reinstalled. At 16 inches x 20 inches x 1 inch, it fits standard filter slots found in furnaces, air handlers, and return-air grilles. The MERV 8 rating meets ASHRAE standards for particulate removal, capturing common household contaminants including dust, pollen, and lint. Licensed HVAC technicians and knowledgeable installers handle replacement and maintenance.\u003c\/p\u003e\n\u003cp\u003eThe 494012 is suited for residential and light commercial forced-air HVAC systems that require a 16 inches x 20 inches x 1 inch filter. Its washable, reusable design eliminates the recurring cost and waste of disposable filters. The electrostatic filtration method maintains airflow while delivering effective particulate capture, making it appropriate for systems where sustained airflow performance and long-term filtration reliability are priorities.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMERV 8 rated per ASHRAE standards for effective particulate removal\u003c\/li\u003e\n  \u003cli\u003eElectrostatic charge generated passively by airflow through synthetic fibers — no power required\u003c\/li\u003e\n  \u003cli\u003eWashable and reusable with a lifetime warranty, eliminating disposable filter replacement cycles\u003c\/li\u003e\n  \u003cli\u003eSynthetic fiber construction resists moisture and maintains structural integrity through repeated wash cycles\u003c\/li\u003e\n  \u003cli\u003eFits standard 16 inches x 20 inches x 1 inch filter slots in furnaces, air handlers, and return-air grilles\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or upgrade for residential and light commercial HVAC systems requiring a 16 inches x 20 inches x 1 inch electrostatic or disposable air filter slot.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a licensed HVAC technician or a knowledgeable installer familiar with forced-air system maintenance. Power down the HVAC system at the thermostat or disconnect before removing or inserting the filter. Verify airflow direction markings on the filter frame align with system airflow before securing. When cleaning, rinse the filter with water and allow it to dry fully before reinstalling to maintain filtration effectiveness.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 16 inches x 20 inches x 1 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMERV Rating\u003c\/strong\u003e: 8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFilter Type\u003c\/strong\u003e: Electrostatic, Washable Permanent\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Synthetic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWarranty\u003c\/strong\u003e: Lifetime\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: NU-CALGON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 494012\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"NU-CALGON","offers":[{"title":"Default Title","offer_id":51347968229682,"sku":"494012","price":79.08,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310552458.jpg?v=1782116875","url":"https:\/\/voomisupply.com\/products\/nu-calgon-494012-electrostatic-hvac-air-filter-16x20x1-merv-8","provider":"Voomi Supply","version":"1.0","type":"link"}
