ABSTRACT:
A filter assembly in an air cleaner includes a lower wire-form adapted to receive two opposite ends of a pliable filter material. Spaced wires on the lower wire-form enable manual forming of pleats in the filter material and define the tops of such pleats. A complementary upper wire-form is engageable with the lower wire-form and attached filter to define the bottoms of such pleats.
