ABSTRACT:
A compact nestable air filter of generally rectangular form comprising a frame formed of an integral suitable cut and scored blank of paperboard, which, when assembled, comprises planar frame members engaging a substantially sheet-form filter element therebetween, and having flared frame members disposed at an angle of less than 180.degree. permitting a plurality of completed filters to nest within each other, thereby reducing the bulk of the plurality of filters. The end portions of the flared frame members may be connected together by several means, including glue flaps hingedly connected to one frame member and adhesively affixed to an adjacent member. In an improved embodiment the planar frame members on the bottom or downstream side of the filter are provided with an integral perforated cover sheet for retaining the filter element in place when subjected to an air current. The flared frame members are provided with edge panels interconnecting the upper and lower panels forming the frame members. As a result the flared frame members have a tubular contour, greatly increasing their strength and rigidity.
