A cartridge locking device ( 10 ) for holding a filter media ( 14 ) in a plenum ( 12 ) in which an actuator ( 112 ) movable between a first position and a second position connects to a lever member ( 122 ) inwardly of the plenum ( 12 ) that moves between a position bearing on the filter media ( 14 ) to a spaced-apart position for replacing the filter media ( 14 ), the locking device ( 10 ) operable from the holding position to the spaced-apart position without opening the plenum ( 12 ), thereby reducing the time for the plenum ( 12 ) to be open during replacement operations. A method of locking and releasing a filter ( 14 ) for filter ( 14 ) change out is disclosed.
