Abstract
A foldable filter having a flexible filter media, a frame surrounding and supporting the filter media, the frame formed of rod members, at least two of which are flexible, each rod member extending between and connecting two corner regions, with the filter media being secured along its edges to the rod members. The filter may be folded by grasping two opposite rod members, rotating the two opposite rod members end over end oppositely relative to one another about a point generally midway along a length of the rod members to effect a relative 180 degree rotation between the two rod members, twisting the filter media, and folding the filter media in half by bringing the two rod members to lie on top of one another.
