According to the invention the bag (4) for filtering dust-laden gas, for a bag filter extending between a plate (1) with holes (2) and supporting and positioning means close to the bottom (3) of a filter casing, is a tubular bag consisting of a U-shaped tube (4) with a flexible filtering wall, permeable to the gas but retaining the dust carried by the latter, which enters the bag (4) and flows, freed from dust, as far as an end opening (9) of the wall opening into a hole (2) in the plate (1) with holes. The U-shaped tube of the bag (4) is fitted in the vessel so that it has two tubular filtering arms (5), which are substantially parallel and whose base (6) is tightened to form a substantially gas proof seal placed near the bottom (3) of the vessel. Application to bag filters for the sanitisation of dust-laden premises and the filtration of outgoing discharges. IMAGE
