A precise fit closes that gap.\u003c\/p\u003e\n\n\u003cp\u003eA MERV 1-4 fiberglass filter is the baseline option for HVAC protection: it stops the larger debris that would foul your coil and blower wheel, at the lowest possible airflow restriction. If your priority is maximum airflow and long blower life, and you're comfortable with frequent replacement, this is the rating that loads your system the least.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003eNominal size: 22-1\/2 x 11-1\/2 x 1″\u003c\/li\u003e\n  \u003cli\u003eActual dimensions: 22-1\/2 x 11-1\/2 x 3\/4″\u003c\/li\u003e\n  \u003cli\u003eEfficiency rating: MERV 1-4\u003c\/li\u003e\n  \u003cli\u003eQuantity: 12 filters per carton\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eCustomers typically order a 22-1\/2 x 11-1\/2 x 1″ custom filter because their system is older, was built by a regional manufacturer, was retrofitted, or was framed on-site by an installer who didn't conform to a standard filter dimension.
