In a dust filter baghouse which employs a small-diameter filter cartridge, the same attachment structure is adapted for installation of the cartridge from either below or above the baghouse tube sheet. The cartridge has an annular cap having an external bead which is received within an annular recess of a skirt portion of a hollow boot which is clamped to the cap of the cartridge and extends up to the tube sheet. Where the cartridge has to be installed from below the tube sheet, a cylindrical cup is provided having an inward flange at its upper end which is secured to the tube sheet. The cylindrical cup has an annular external recess which receives an annular internal bead on the hollow boot. Where the cartridge is installed from above the tube sheet, an external annular groove in an outwardly extending flange at the upper end of the hollow boot is received within the peripheral edge of the hole in the tube sheet.
