Parts Have owned a inogen G3 for a little over 2 1/2 years.Zero problems ,but I do have a question.I have ordered and received New filters. Have calls many times but cant6 get anyone to talk to. I replaced the old ones, but for some reason I don't think they are working as well as the ones I took out.I was reading that there is a filter behind where the tube hooks up to the machine and was wondering if it may need to be changed.There is a tool that must be ordered,so I read. AND HELP WOULD BE NICE THANK YOU ANDY H.505 688 9763

Really unprofessional company to shop… Really unprofessional company to shop from . We ordered a pair of oxygen concentrator Column and was supposed to be shipped to us and it never did after a week.I followed up several times and apparently I couldn’t get on the phone with the supervisor. They said just email Greg. So the order was finally canceled at the end. I do not recommend this unprofessional company to anyone. Order #472612

100% satisfied 100% satisfied. Easy ordering, delivered at time promised, priced as offered.

Now I need a portable I recently bought my first portable oxygen machine from Sleep Direct/Oxygen Direct.com. An emotional time for sure. Getting used to the machine and the new life did not happen overnight. Then I realized I was feeling pretty darn good and able to do more. Then I realized it was running really hot, an Inogen G4. I let Greg, my sales rep, know what was going on half holding my breath preparing for a run around. He was on it. Sent me a loaner I never expected and had me send the machine back in. It was repaired with replacement parts and returned to me. Now not running quite as hot but still hot, hotter than the batteries are recommended to be at. I let Greg know again of my dissatisfaction. Next day I get an email a new one is on the way. I so appreciate Greg's quality customer service and Oxygen Direct's commitment to satisfaction. I did have to pay return shipping both times but I did not mind, a small part of the investment to have a smooth cool running machine. They shipped 3 times at their expense.

High recommended Liable! Great costumer service and affordable price! Definitely the best in Uk! A big thanks to Jarod!
