Each filter is nominally sized at 18x20x1 inches with actual dimensions of 17.75 x 19.75 x 0.75 inches. The polyester green media captures airborne particles including dust, pollen, and common household allergens. These filters are manufactured in the USA and are constructed from environmentally responsible materials. Licensed HVAC technicians and knowledgeable homeowners install this filter as a standard 1-inch replaceable media panel filter in forced-air heating and cooling systems.\u003c\/p\u003e\u003cp\u003eThis filter is suited for residential forced-air systems and light commercial HVAC applications where standard 1-inch media filters are specified. The MERV 6 rating makes it appropriate for systems requiring basic particulate filtration without creating excessive static pressure drop. The 4-pack format reduces service call frequency and supports routine filter change schedules. Installations in homes, offices, and similar occupied spaces where dust and pollen control is the primary filtration goal are typical use cases for this filter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMERV 6 filtration rating captures dust, pollen, and common airborne particles\u003c\/li\u003e\n\u003cli\u003eActual size of 17.75 x 19.75 x 0.75 inches for accurate fit in compatible filter housings\u003c\/li\u003e\n\u003cli\u003ePoly Green polyester media constructed from environmentally responsible materials\u003c\/li\u003e\n\u003cli\u003eManufactured in the USA\u003c\/li\u003e\n\u003cli\u003eSold as a 4-pack to support scheduled filter replacement intervals\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement panel filter for residential and light commercial forced-air HVAC systems that accept a nominal 18x20x1 inch filter.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by HVAC technicians or qualified building maintenance personnel.
