A filter and support structure, for a baghouse having a tube sheet with a plurality of apertures, has a filter media wrapped around a core. An end cap is joined proximate the top of the core and has a rim extending over the filter media. The rim of the end cap is joined with a collar having a downwardly depending annular barrel. The barrel has a pair of outwardly protruding ribs. A snap band assembly has a metallic snap band, spring-biased outwardly, and covered with fabric. The snap band assembly has upper and lower outwardly protruding portions. The snap band assembly receives a periphery of a tube sheet aperture between the upper and lower outwardly protruding portions. The upper rib of the pair engages with the inner face of the snap band assembly proximate the plane in which the tube sheet lies, or slightly below that plane. The collar has a flat upper portion which is spatially removed from the snap band assembly and a downwardly depending annular flange which engages with the top of the tube sheet. A plurality of cutaway areas are spaced around the flange for receiving a pry bar.
