The concentrator columns are very easy to replace and can be done at home without any need for special tools. Only replace these columns when the low-priority alarm ‘change column soon’ is present. Make sure to use the concentrator at least 10 hours a month, and keep the concentrator columns sealed when not in use for a long time.

To clean the oxygen concentrator, just use a damp cloth and wipe the machine and the exhaust port. You can wipe the surfaces with isopropyl alcohol or any equivalent antiseptic to disinfect the concentrator. The machine should not vibrate or make any excessive noise when in operation. If such issues occur, unplug the device and send it right away to the Inogen service center.

Note that any visible damage to the concentrator must be repaired only at the Inogen service center. Do not overcharge the unit. Make sure to keep up with the maintenance to ensure that the concentrator works reliably every time.

Don’t Go for Cheap Oxygen Concentrators!

Machines like oxygen concentrators should have high-quality design and adhere to local standards. Cheap oxygen concentrators for sale are neither reliable nor safe, so buying one is often hit or miss. They are not designed for sustained use because of poor craftsmanship or poorly-done electronics.

If something goes wrong, there is no way to have them serviced. You cannot depend on them. Lastly, they are not comfortable to use. Choose safety and real performance. Only choose brands that have years of presence in the market and have certifications.

I love the freedom that it gives to my father in law who was once stuck at home cause he could pick up and carry the big tank in the vehicle, now he can go mobile. Thank Inogen for making something like this.

N. Orton
The product is excellent.

The product is excellent and quite useful, to say the least. The batteries charge very quickly and stay charged for a long time and the oxygen is always there and always ready no matter where I happen to be - home or away.

J. Bollinger

The Inogen One G5 is an excellent portable O2 concentrator on the market. It does everything the floor units can do. Very little noise. I sleep peacefully with the unit 2 feet from me.

Charlotte L.

I am very happy with my Inogen, it is easy to handle and allows me complete freedom to move about when going out or working in my apartment. I am very pleased with it and am happy that I spent the money for it.

A. Sparks

I have the G5 and I am free now to be active for 4 hours without worrying about oxygen supply.

D. Kelley

My Inogen is a lifesaver. When I was using tanks for being away, I had to take at least 5 everywhere I went. They only lasted about an hour and a half. I now have freedom. Also, my home unit is a great savings. Love my Inogen.

Kathy P.

I was diagnosed with pulmonary fibrosis after a bout with covid in January 2021. I am now dependent on oxygen 24/7. I found Mobility Paradise online and with great customer service, I purchased from them Inogen one G5. The best decision I've made.

Charlene C.

The portable G5 unit allows me to maintain some level of normal outside activity. It allows me to bring it with me to other locations.

J. Cross

Love it, the G5 is working perfectly so far. Thank you. Helped me a lot daily.

Judy W.
Compact and effective.

I love my Inogen oxygen concentrator. it is compact, quiet, and energy efficient. I like owning my own equipment as it is much cheaper than renting one.
