Measuring 12 inches by 20 inches by 1 inch, it fits standard residential furnace filter slots without modification. The EZ Flow II design uses spun fiberglass media with no metal retainers, keeping the filter lightweight and easy to swap out. It is rated as a 30-day filter, making it suited for high-change-frequency applications or systems where low static pressure drop is a priority. HVAC technicians and residential service pros install this type of filter as a baseline protection layer for furnace blower components against large-particle debris.\u003c\/p\u003e\n\u003cp\u003eThis filter is designed for use in residential forced-air furnaces and air handlers where a flat-panel, 12 by 20 by 1 inch filter is specified. Its MERV 4 rating captures large particles such as dust and lint, making it appropriate for systems where airflow capacity takes priority over fine-particle filtration. It is sold in a package of 12 units, which supports bulk stocking for service routes or multi-unit residential properties. The 30-day service interval keeps maintenance cycles straightforward on standard-use residential systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eMERV 4 rating — captures dust, lint, and other large-particle debris\u003c\/li\u003e\n  \u003cli\u003eSpun fiberglass flat-panel media with no metal retainers for easy, tool-free removal\u003c\/li\u003e\n  \u003cli\u003e30-day rated service life for predictable replacement scheduling\u003c\/li\u003e\n  \u003cli\u003eDimensions: 12 inches x 20 inches x 1 inch — fits standard residential filter openings\u003c\/li\u003e\n  \u003cli\u003eSold in a case of 12 units, suitable for bulk stocking\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement flat-panel furnace filter for residential forced-air heating and cooling systems requiring a 12 x 20 x 1 inch disposable fiberglass filter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by HVAC technicians or qualified service personnel.
