The invention relates to a method for filtering liquids, especially biologic al liquids. A filter (1) is deposited with the auxiliary filtering agent during a pre-deposition phase. In an ensuing filtration phase, the infiltrate is filtered by adding an auxiliary filtering agent. The auxiliary filtering age nt forms a filter cake during the pre-deposition phase and the filtration phase . The auxiliary filtering agent is deposited during the pre-deposition phase, the proportion of regenerated auxiliary filtering agent being 30 %, especial ly 0 %. During the filtration phase, an auxiliary filtering agent is added, consisting predominantly, especially almost fully, of regenerated auxiliary filtering agent. The regenerated auxiliary filtering agent is treated with a medium over the whole pH value spectrum.
