A device for conditioning breathing air includes a housing ( 1 ) provided with an inlet ( 5 ) for non treated breathing air and an outlet ( 6 ) for the treated breathing air. The housing ( 1 ) contains a passive humidifier ( 7 ) and an active humidifier wherein the active humidifier includes a water supply inlet ( 13 ), a heating device for the supplied water, a membrane ( 12 ) having substantial water impermeable and water vapor permeable characteristics, and a heat exchange element ( 14 ). The membrane ( 12 ) is divided into a hydrophilic membrane ( 12 a) and a water vapor permeable and water impermeable membrane ( 12 b). The heat exchange element is a perforated metal plate ( 14 ) and/or a heating resistance. A method for the conditioning of breathing air includes the steps of: supplying through the inlet opening non treated breathing air, passively humidifying the supplied air through the passive humidifier, and actively humidifying the breathing air, through the active humidifier of a device. |
