Abstract

The present invention relates to an air humidifier and to a method for humidifying air, the use of special devices enabling air to be humidified with sterile water. A large contact area between water and air is combined with low losses of flow pressure. A membrane contactor having at least one tube membrane embedded in a hydrophilic, porous body comprises the air humidifier. The present invention enables use of coarse filters to ensure that the water is dispersed over a large surface area.
