Abstract
A filter assembly for filtering air comprises a filter housing and a filter which is removably positioned within the housing. The filter housing includes spaced-apart first and second housing portions which are connected by connecting members on opposite sides of the housing, and the filter is positioned between the two housing portions. One end of each of the connecting members is secured to the first housing portion, and the other end of each connecting member is connected to the second housing portion in a manner which permits the second housing portion to be moved along the connecting members toward and away from the first housing. When the second housing portion is moved away from the first housing portion, the filter can be removed.
