Abstract: Provided is an apparatus for receiving a filter member. The apparatus, in this embodiment, includes a plurality of discrete substantially rigid frame sections. In this embodiment, each respective section of the plurality of sections lies generally in a respective plane substantially oriented about a respective axis and has a respective length greater than a respective width. Furthermore, in this embodiment, the plurality of sections are joined width-to-width generally oriented with respect to a plane in an assembled orientation to circumscribe a quadrilaterally bound zone for effecting said receiving. Further to this embodiment, adjacent portions of respective joined sections in the assembled orientation establish respective joining structures. Even further to this embodiment, each respective joining structure maintains the adjacent portions oriented substantially about a respective axis.

Abstract: A frame for receiving a filter element includes: a pair of first members and a pair of second members. The first members may be arranged alternately with the second members in the assembled orientation to establish a plurality of joining structures between adjoining members. Each respective joining structure of the plurality of joining structures maintains the adjoining members oriented substantially about a respective axis. The first members and the second members cooperate to define a volume for effecting the receiving.
