  • Patent number: 7461835
    Abstract: An air humidifier has an electric fan unit arranged in a housing for delivering a through-flow of air between feed-air and discharge-air openings in the housing; at least one filter device for the through-flow of air; and a device for releasing liquid to the through-flow of air. A first housing component accommodates the fan unit with filter strips and feed-air and discharge-air openings. A second housing component is a vessel for storing liquid. The two housing components form autonomous structural units which can be fixed to and detached from one another. It is possible for the first housing component to be utilized as a separate unit independently of the second housing component.
