An aircraft cabin humidification system for humidifying an air mass within the cabin. The system comprises: (a) means for ventilating the cabin with a ram air stream; (b) means for humidifying the air of the ram air stream so as to maintain a desired level of humidity within the cabin; (c) means for exhausting at least a portion of said air from the cabin; (d) removal means for at least partially removing moisture from the air removed from the cabin; (e) recycle means for recycling at least a portion of the moisture from the exhausted air; and (f) humidification means for humidifying the cabin by adding at least a portion of the removed moisture to the cabin. A method for ventilating an aircraft cabin comprising the steps of: (a) injecting ram air into the cabin; (b) humidifying the ram air by injecting moisture therein; (c) exhausting air from said cabin; (d) removing moisture from the exhausted air of step (c); (e) recycling the removed moisture of step (d); and (f) reinjecting the removed moisture into the ram air. A method of reducing the ozone level of a gas comprising the step of irradiating the gas at a frequency of about 253.7 nm.
