It fits any system that takes a \u003cstrong\u003e16 x 25 x 4\u003c\/strong\u003e filter (16x25x4). This case contains \u003cstrong\u003e6 filters\u003c\/strong\u003e. At a typical 6–12 month change, that is three to six years of filters for one system.\u003c\/p\u003e\n\u003cp\u003eMulti-Pleat XL11 uses 100% mechanical filter media rated MERV 11, so its efficiency does not depend on an electrostatic charge that can fade over time. A galvanized expanded-metal support grid is laminated to the media, the pleats are bonded to the frame to prevent air bypass, and the double-wall, moisture-resistant beverage-board frame with reinforced corners stays rigid in humid conditions.\u003c\/p\u003e\n\u003ch3\u003eIs This the Right Size?\u003c\/h3\u003e\n\u003cp\u003eAir filters are sold by \u003cstrong\u003enominal size\u003c\/strong\u003e, the rounded size printed on the frame of your current filter. The filter itself is made slightly smaller so it slides into the filter slot — typically about 1\/2\" under nominal on length and width, and 3\/4\" deep for a 1\" filter.
