What brand is your oxygen concentrator?

We use our own oxygen concentrator that is designed to be used for EWOT.  It offers 93% oxygen purity – which is medical grade and the most common oxygen purity out there. 

Our systems have been out in the field since 2018 and we have yet to hear back from a customer who has worn theirs out.  Oxygen concentrators are designed to be used 24x7 for people with chronic health conditions, so our application is relatively low duty and the machine is likely to last you a very long time.
