An apparatus for releasably clipping to a frame an element for removing particulates, impurities, and/or moisture from an air stream, the apparatus preferably comprising: a self-aligning attachment post; a clip which is longitudinally movable on the post; and a locking member which can be pushed inwardly on the post and which interacts with one or more locking tabs in a manner effective for compressing a biasing member and locking the biasing member in a compressed position for holding the clip in engagement with the element. The apparatus preferably also comprises a handle clip on the outer portion of the attachment post which can be pulled and rotated for installing or removing a second element and can be rotated to a second position and released such that the handle clip will automatically hold the second element on the frame.
