Abstract
A filter assembly is provided having a housing and a cover that communicate to retain a filter element. The housing has a top and a bottom spaced apart from each other, and a first pair of guide members is maintained beneath the top while a second pair of guide members is maintained above the bottom. The filter element is retained in the housing between the first and second pair of guide members thereby defining a first cavity between the top and the filter element and a second cavity between the bottom and the filter element. Fasteners, such as screws, rivets, nails and the like, may communicate with the cavities without damaging the filter element. The first and second pair of guide members allow for access to the internal surface area of the top and bottom of the housing such that fasteners or other installment means can be employed from the inside of the housing outwardly to the duct work or framework to which the filter assembly is to be attached.
