Among the 7.6 billion people around the world, there are different types of deficiencies among many. One of them is being unable to get enough oxygen into a person’s body from the natural air.
The medical term for this deficiency is hypoxia. People who suffer from hypoxia need either intermittent or constant supply of additional oxygen to keep them going.

The portable oxygen concentrator, also known by its acronym POC, is a great resource for hypoxia patients. You can carry it around and use it whenever necessary. There are variations that suit the needs of both the intermittent user and the constant user. Unlike regular consumer products, these products are very critical and they are used for the most vital need of the human body, oxygen. For that very purpose, we bring to you almost all the available POCs with their basic specifications.
