ABSTRACT:
A filter frame that includes a hinge structure for coupling a series of like filter frames together such that the series of filter frames may be folded together. Moreover, the filter frame includes a series of separable sub-sections that correspond to standard filter sizes. This enables an original filter frame to be "broken down" to a number of smaller standard sizes.
