Abstract

A filtering mass for filters for fluids, comprising at least one layer (1), which is made of paper and is meant to be the first one crossed by a fluid in order to provide coarse filtration, and a second layer (2), which is made of glass fiber and is suitable to provide fine filtration. The filtering mass further comprises at least one layer (4, 5) of non-woven fabric in contact with the surface of the layer (2) made of glass fiber that is directed toward the outlet of the fluid.
