Abstract (en)
[origin: EP2630993A1] The invention relates to a filter cartridge (1) for an air filtering device, in particular for a filtering face mask (15), comprising a stiff cup-shaped casing (2) having a bottom (4) and a circumferential sidewall (5) extending at least section-wise parallel to one axis, a stiff discoidal lid (3) and a filter bed (14) of loose filter material compressed between the lid (3) and the casing (2), the lid (3) and the bottom (4) containing each at least one through-hole (6,7) so that air to be filtered passes through the filter bed (14), and at least one of the lid (3) and the bottom (4) being curved to at least one direction, whereby the lid (3) is at least essentially arranged within the casing (2), the outermost contour of the lid (3) close-fitting to the inner contour of the sidewall (5), and fixed thereto by a direct connection, particularly by a non-detachable connection. The invention further relates to a filtering face mask and a method for manufacturing a filter cartridge.
