Abstract
A humidifier comprises a container having an air inlet and an air outlet; a water reservoir in the container; an absorbent mass having extensive upper surface and lower surfaces, the absorbent mass being floatable on the surface of water in the reservoir; a plate disposed on the lower surface of the absorbent mass to limit the degree of immersion of the absorbent mass while it floats in the reservoir; and a blower for drawing air through the air inlet and directing it onto the upper surface of the absorbent mass so that the air can deposit particles thereon, and absorb moisture therefrom, prior to flowing out of the container through the air outlet. The humidifier is highly efficient, quiet in operation and not affected by varying water levels.
