MyOxy portable oxygen can is India's first FDA approved disposable oxygen can with inbuilt mask. It is very useful in case a person is suffering from breathlessness caused due to various reasons like high altitude, pollution or any respiratory problem. Oxygen makes up around 21 per cent of Earth & atmosphere, and humans use it the most. It is the key ingredient in the production of energy and every breath that we take converts to energy. When the oxygen level drops, energy drops and performance drops.
