Oxygen Plus, Boost Oxygen, Oxygen 4 Energy, and O2 Naked Air are a few of the companies selling canned oxygen online, in specialty stores and spas.

The product is also sold online. Because canned oxygen is not medical or industrial oxygen, it can be purchased over the counter and does not require a prescription or license.

Boost Oxygen is an innovative way to catch your breath at high altitudes and other situations that require a bit more oxygen but will the sharks want in?
