| I would suggest typing "oxygen concentrator"., not "oxygen machine". Correct terminology should speed up your search process.
I'm on 4Lof O2 24/7 (or should be) right now. I have a concentrator in the house and a few M tanks and a couple E tanks to go with. With this setup I feel basically housebound. I'm gonna have to get more tanks for portable use. I'm thinking of a portable concentrator that runs on its own battery or plugs in to the car or tractor. | |
