In many remote communities, the thought of electricity is a distant reality. This leads to the notion of using oxygen therapy as being equally remote.

Oxygen is an essential medicine.

FREO2 - Siphon is an electricity-free oxygen concentrator which is durable, affordable and has no ongoing costs. The system harnesses energy from a small amount of running water to  separate oxygen from the surrounding air. Additionally, the device avoids some of the maintenance problems common to contemporary electrical oxygen generators.

FREO2 - Siphon aims to give people greater control over their health by providing community health clinics with a vital tool in the fight against pneumonia.
