Improvements in filtering bodies consisting of a sheet of paper material or the like whose leaf is folded in a zigzag pattern, which bodies, both on the inlet side, as well as on the outlet side, have grooves between the edges of the folds, arranged transversely to said edges and parallel to each other, serving for the reciprocal distancing of the folds, the grooves of the contiguous folds surfaces being juxtaposed, characterized in that each of the grooves on the inlet side is combined with a groove on the side of exit to form a pair of grooves, for which there is no transition between its neighboring flanks, while between the pairs of grooves of the same fold surface sections have been left undeformed.
