An entirely disposable combined antimicrobial filter and flowmeter device for spirometry applications comprises a tubular body, with an inlet end portion, an outlet end portion, and an intermediate portion of enlarged diameter in the form of a discoidal shell. In the discoidal shell both an antimicrobial filtering membrane and a discoidal net of plastic material generating a pressure differential are arranged, it has an outer peripheral edge fixed to an inner annular lip of one of said bell-shaped portions of the discoidal shell, said annular lip being coaxial to said cylindrical wall. One of the filtering membrane and the pressure differential generating network has an outer peripheral edge fixed to the cylindrical wall of the discoidal shell, while the other of the filtering membrane and the pressure differential generating network has an outer peripheral edge fixed to an inner annular lip of one of the bell-shaped portions defining the discoidal shell.
