The invention allows users to be totally submerged underwater with an adequate supply of air for extended periods of time without the use of regulators, pressure vessels, diaphragm pumps or compressors, internal combustion engines or external power sources. The apparatus includes a buoyant enclosure supporting a hollow air intake pipe with a sphere shaped screen mounted on the top. The bottom half of the screen has holes to allow air into an air intake tube and to drain water out. A low pressure blower and filter assembly with a rechargeable and easily replaceable lithium-ion battery are mounted inside the buoyant enclosure. Air is drawn into the low pressure blower suction and through an air filter delivering constant air flow to the individual through an attached flexible air supply hose. Three check valves constrain air flow supply unidirectional to the individual while venting excess air. A hand pump vacates water from the mouthpiece or mask and draws in purging air while the individual is submerged. For stability the apparatus has a low center of gravity creating a strong self-righting moment in calm or rough seas. For safety the apparatus has a grab handle and a tether line connection from the bottom of the buoyant enclosure.
