I have the Longevity Resourses ext 120 ozone generator and let me just say
I is one of the best little investments I ever made. You will be very pleased with that choice.
As far as oxygen concentrators, I'm currently using the oxycur 5000. I also have an Invacare
and a Devilbliss. What a great little team, very powerful. You should read up on everything that
