Sold in a 4-pack, each filter carries a nominal size of 18x18x1 inches and an actual size of 17.75 x 17.75 x 0.75 inches for a precise fit in standard filter slots. The Poly Green construction uses environmentally responsible materials, making it a practical choice for facilities managers, HVAC technicians, and property owners who prioritize both filtration performance and reduced environmental impact. Installation requires no special tools and takes only minutes during routine maintenance.\u003c\/p\u003e\u003cp\u003eThis filter is suited for residential homes and light commercial office spaces where standard particulate control is required. The MERV 6 rating makes it appropriate for systems that need protection against dust, lint, pollen, and mold spores without creating excessive static pressure on the air handler. It fits into any standard 18x18x1 filter rack or return-air grille designed for that nominal size. The 4-pack format supports a full year of quarterly filter changes in a single purchase, which is practical for scheduled preventive maintenance programs.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMERV 6 filtration captures dust, pollen, lint, and mold spores\u003c\/li\u003e\n\u003cli\u003eActual size of 17.75 x 17.75 x 0.75 inches for accurate fitment in standard 18x18x1 slots\u003c\/li\u003e\n\u003cli\u003ePoly Green construction uses environmentally responsible polyester media\u003c\/li\u003e\n\u003cli\u003eSold as a 4-pack to support quarterly replacement schedules\u003c\/li\u003e\n\u003cli\u003eManufactured in the USA\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a direct-fit replacement for standard residential and light commercial HVAC systems using a nominal 18x18x1 inch filter size.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified HVAC technician or a knowledgeable property owner familiar with their system.
