Lufthansa Technik has ordered a CTT Cair humidifier to be installed in a VIP Boeing 747-8, having already installed the system in five wide and narrowbody aircraft.
Cair provides humidification of dry aircraft cabins without causing condensation, giving a relative humidity of around 20%, compared to 3-5% without. CTT says that this reduces dry air related problems such as fatigue, jet-lag, red eyes, dry skin and the spread of virus diseases.
