Abstract: A medical airway device includes a housing having at least one breathing circuit port and including an airway filter arranged to filter air flowing through the at least one breathing circuit port. The airway filter includes a layered filter including at least a first separate filter layer and a second separate filter layer being stacked on top of each other so that neighbouring separate filter layers abut each other. The layered filter has a first surface being laminated with a first scrim layer and a second surface being laminated with a second scrim layer. Each separate filter layer is a non-woven fiber layer.
