This invention is a disposable active humidifier used in conjunction with mechanical ventilation of a patient, having a cartridge (1) which forms a humidification chamber (2) which is delimited by an inlet (3), an outlet (4), and can be interposed in the ventilation circuit (40). The cartridge (1) has an interspace (11) which is externally delimited by a heat exchange surface, and is internally delimited by a hydrophobic membrane (12) which surrounds the humidification chamber (2). A humidification fluid, e.g., water, originating from a bottle or bag, can be introduced in the interspace (11).
