Mini-Pleat air filters are available in minimum-efficiency reporting value Nos. 13, 14 and 15, and in 1-inch, 2-inch and 4-inch sizes. The panel filters are made from 100 percent plastic with rigid frames that can be used with gaskets to eliminate filter bypass, according to the company. The company also claims that the filters' large surface area allows for extended life and low-pressure drop.
