ABSTRACT:
A filter frame formed from a stock channel member having a generally U-shaped cross-sectional configuration. The channel member may be provided in stock lengths which may be cut on-site to the desired size to form each side of a filter frame when assembled together. The cut lengths of the channel members may be assembled together in the appropriate configuration to match the filter being replaced, and a mass of filter medium cut to a corresponding configuration and placed within the cavity formed by the u-shaped cross-section of the channel members to form the air filter. The channel members are also provided with a plurality of U-shaped grooves in the upstanding legs of the channel members which form tabs. The tabs may be advantageously employed with a length of elongated material to form a protective screen. Specifically, a length of elongated material, such as string, may be wound about the tabs and across the length of the air filter to be wound through separate tabs. Repeating this process forms a substantially taught web of the elongated material which functions as a protective screen to maintain the filter medium in position.
