ABSTRACT:
A one-piece framework for holding the filter media of an air filter includes a pair of end walls integrally connected to a pair of frame members by a living hinge so that they may be pivotally moved between an assembled position and an unassembled position. A pair of sidewalls are integrally connected to the frame members by a living hinge only at their outermost ends so that they, too, may be pivotally moved between their assembled and unassembled position. Each of either of the sidewalls or end walls is provided with a tab-type latch which includes a button undercut at least a peripheral portion thereof. Each of the other sidewalls or end walls has an opening formed therethrough. The opening is defined by a wall shaped in accordance with and frictionally surrounding the undercut button in a snap-fit to hold the sidewalls to the end walls in an assembled state.
