Abstract

The invention relates to a moisture-heat exchanger unit for tidal air of a patient. The unit comprises a housing (42, 43) arranged for the flowing through of the air. In the housing (42, 43), a filter (44) having the capability of absorbing and desorbing moisture is arranged. According to the invention, there is a rotary valve (48, 49) arranged in the housing (42, 43) for the provision of two alternative flow paths of the air through the housing (42, 43). A first flow path entails that the air flows through the filter (44) and a second flow path entails that the air flows through the housing (42, 43) without flowing through the filter.
