HDX 10 In. X 20 In. X 1 In. Standard Pleated Air Filter FPR 5, MERV 8

HDX filters are constructed of a durable, moisture-resistant frame with wire supported media for strength and rigidity. The wire-backed Pleated media offers a large surface area which increases the filter's dust-holding capacity and improves its efficiency. The air filter media can be charged electrostatically which means it attracts, captures and traps particles that would otherwise bypass the filter. The air filter's media is rated between a MERV 8 and 13, which is one component of the FPR Rating. FPR or the Filter Performance Rating, is composed of 4-measurements for classifying air filters.
