Open O2

We are a hub for innovation and information in the space of oxygen concentration technology used in low-income countries

We are based in Lilongwe, Malawi, and operate as a Center within the

Oxygen is essential for life, and plays a key role is medical care. In many low-income countries bottled oxygen is not readily available. An oxygen concentrator is a device used to increase the percentage of oxygen by removing nitrogen from room air. The process is relatively straightforward and has been around for more than 40 years. However, concentrators need periodic maintenance to replenish the zeolite, the chemical used to remove the nitrogen from air. Additionally some of the components required to run older models of concentrators are no longer available as some of models of concentrators found in low-income country settings have been out of production for more than a decade. As a result of this, many low-income countries are scattered with graveyards of oxygen concentrators that have been written-off as no longer repairable.

Our vision is to see a significant proportion of broken concentrators restored to working condition and maintainable in a sustainable way to continue to provide life-saving oxygen.

Our Mission is to provide public and private organizations in low-income countries with access to resources including repair manuals, training materials and replacement parts for obsolete models of concentrators, some of which have been developed under an open source design framework and can be made using locally available materials.

Help us to crowd-source our library of oxygen concentrator models, descriptions and resources. If you have a concentrator that needs maintenance that is not listed in our library please email the make and model number of your concentrator to and we will add it to our library and try to populate with details.
