The said invention or apparatus is for users to swim and be totally submerged underwater with an adequate supply of air for extended periods of time. The apparatus is a sealed water resistant enclosure supporting a hollow air intake pipe with and attached hollow air intake sphere mounted on the top. The bottom half of the air intake sphere has many holes to allow air into air intake riser and drain unwanted water out. The apparatus does not require regulators, pressure vessels, diaphragm pumps or compressors, internal combustion engines or external power sources. A low pressure blower and filter assembly with a rechargeable and easily replaceable lithium ion battery are mounted inside the buoyant water resistant enclosure. Air is drawn into the low pressure blower suction and through an air filter delivering constant air flow to the swimmer through an attached flexible air supply hose. The apparatus uses three check valves to constrain air flow supply unidirectional to the swimmer while venting excess air. The apparatus has a hand pump to vacate unwanted water from the mouth piece or mask and draw in purging air while the swimmer is submerged. For stability the apparatus has a designed center of gravity below the meta center of the underwater portion of the buoyant water resistant enclosure giving a positive GM and 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 water resistant enclosure. The tether line is attached to the swimmer.
