A floating portable humidifier is configured to float partially submerged in an open tray of water. An internal cavity includes water entry apertures below the water line and air entry apertures above the water line. Water enters the cavity through the water entry apertures to establish a constant water level within the cavity. Humidifying apparatus installed within the cavity combines water and air to form humidified air that leaves the humidifier through air exit apertures. A motor-driven fan may assist circulation of humidified air. Sealed chambers or a porous closed cell body construction may provide the necessary buoyancy. Any humidifying apparatus may be used. The floating design eliminates the need for a water tank.

1. A portable humidifier that floats on water, said portable humidifier comprising: a buoyant body having a predetermined buoyancy in water and defining a cavity and including at least one water entry aperture and a plurality of air apertures, at least one of said air apertures comprising an air entry and at least one of said air apertures comprising an air exit, said air entry comprising a pair of diametrically opposed openings and said air exit comprising a plurality of openings arranged in a plurality of concentric rings; a humidifying apparatus disposed within said cavity for humidifying air in said cavity; and power supply means for supplying power to said humidifying apparatus, wherein said portable humidifier has a weight and the predetermined buoyancy of said buoyant body is calculated so that a first portion of said buoyant body is submerged and a second portion of said buoyant body is above the water, said water entry aperture provided on said first portion and water entering said water entry aperture is accessible to said humidifying apparatus, said humidifying apparatus combining said water and air entering said cavity through said air entry to form humidified air which then exits said cavity through said air exit, said air entry positioned closer to the first portion of the buoyant body than the air exit. 2. The portable humidifier of claim 1, wherein said predetermined buoyancy is provided by a sealed pocket of gas attached to said buoyant body. 3. The portable humidifier of claim 1, wherein said predetermined buoyancy is provided by constructing at least some of said buoyant body from a material having a specific gravity less than water. 4. The portable humidifier of claim 1, wherein said humidifying apparatus is selected from the group consisting of an evaporative humidifying apparatus, an ultrasonic humidifying apparatus, and a heating element based humidifying apparatus. 5. The portable humidifier of claim 1, wherein said power supply means comprises a power cord operatively connected to said humidifying apparatus. 6. The portable humidifier of claim 5, wherein said power cord is operatively connected to a transformer that supplies said power supply means with low voltage direct current electricity.
