In a top access multiple filter bag device having a housing, a cell plate subdividing the housing into an upper clean gas plenum chamber and a lower dirty gas plenum chamber including a baghouse, in inlet to the dirty gas plenum chamber for the introduction of gas to be cleaned and an outlet from the clean gas plenum chamber for removal of filtered gas, filter bags of circular cross section depending from the cell plate into the dirty gas plenum chamber, circular openings in the cell plate dimensioned to enable the filter bags to extend therethrough for suspension from the cell plate into the baghouse, and means for releasably securing each filter bag to the cell plate, the improvement wherein each filter bag is of decreasing cross section from the upper end portion to the lower end portion so that, as the filter bags are withdrawn from the baghouse through the openings in the cell plate, the clearance between the bags and the cell plate wall defining the corresponding openings increases to ease the removal of the filter bags, a wire cage of circular cross section is dimensioned to be received in fitting relation within each filter bag for support, with corresponding decrease in cross section from the upper end portion to the lower end portion, and means for supporting each cage from the cell plate independently of the filter bags.
