A method for filtering a suspension, the suspension initially being inducted into a filter chamber in a direction which is substantially parallel to at least one filter cloth on a filter cake side of same, the filter chamber being configured substantially lens shaped between two parallel filter plates, when a filter device is closed, whereas when the filter device is open, the filter plates are at such a distance that the at least one filter cloth can be removed from the filter chamber, thereafter a filtrate to permeates the at least one filter cloth to a filtrate side of the filter cloth, wherein a solid content of the suspension is deposited as a filter cake on the filter cake side, and the filtrate subsequently flows out of the filter chamber on the filtrate side. The invention also relates to such a filter device. In order to be able to homogeneously create or wash the filter cake over the filter cloth, the inducted suspension and/or a washing liquid for washing the filter cake on the filter cake side induces an annular flow about a central axis of the filter chamber, said axis being perpendicular to the at least one filter cloth, or the filter device comprises a plurality of induction elements, disposed substantially in a separation plane of the filter plates rotation symmetrical about a center. The suspension or a washing liquid for washing the filter cake can be inducted through the induction elements in an inlet direction, which comprises a radial component oriented towards the center of the filter chamber and a tangential component perpendicular to the radial component.
