Best Opensource Oxygen Concentrators 2021.

In this article, I had researched and collected information about the best open source oxygen concentrators.

All these oxygen concentrator designs and technical information are available online and free to download so that you can start making it your own.

As we all know because of the covid-19 pandemic since the rate of affected people all over the world has been increased drastically.

So we need more medical equipment and supplies to meet the requirement of hospitals and patients.

And the requirement of compressed treated oxygen is very high, and also because of lockdown around the different parts of the country and states supply chain is also disrupted.

In this situation, the maker’s communities are coming forward and started making oxygen concentrators locally to meet the peak demands to save the lives of our people.

So, here I am sharing a few open-source designs that you can work on and be ready for any future emergency.
