In a process and apparatus for cleaning dust-laden untreated gases, in particular at elevated pressure and elevated temperature using a plurality of filter units (4) having filter elements (41), which filter units are connected in parallel via gas connections (11, 21) between untreated gas duct and clean gas duct (1, 2), the filter units (4) being able to be uncoupled from the gas flow individually or in groups, one shut-off element (12, 22) each is arranged in the untreated gas duct and in the clean gas duct (1, 2). The shut-off elements (12, 22) have at least one covering surface (13, 23), matched to the geometry of the duct interior wall, for the gas connections (11, 21). Filter units (4) to be cleaned are uncoupled from the gas flow and cleaned filter units are reconnected into the gas flow by sliding the shut-off elements (12, 22). <IMAGE>
