Inogen Portable Oxygen Concentrators

I own a G4 and rent a G3 and stationary unit with continuous flow for use at night. I travel by air without problems and my G4 is small, comfortable and sturdy. I use the G3 for backup. Whenever I have had any issues or needed replenishment supplies, Inogen has been helpful and prompt. I purchased and rented directly from Inogen and have been a customer since 2015.

My mother is on oxygen 24/7. She lives alone. Currently, her portable unit (Inogen 1) won’t hold a charge. She has called customer service MULTIPLE times without success.

I called (877)466-4364 tonight and they aren’t able to call me back until Monday. She has no way to get to the pharmacy to retrieve her meds. This is absurd. I will be transferring my mom’s care to a different company.

I bought this machine (mdl #4???) more than 3 years ago. ABSOLUTELY the BEST. My insurance co supplied me with two different machines and they both broke down within 14 day. Were very noisy and unreliable. THANKS guys for such a GREAT machine!!! The double battery is WORTH the extra money.

I have had nothing but problems since the day the concentrator was received. The salesman lied to me again and again. I was told that in order to get the portable Inogen I would have to buy the whole unit which includes the oxygen concentrator.

He also told me that Medicare would send me the monthly payment and that I should send that money to first class medical. After speaking to Medicare they informed me that they never send patients payments.

I also talked to a supervisor at Care Airways Co. and all he did was call representatives at Medicare "bone heads". The total bill came to $4500. I was switched to a finance company which I thought was first class medical.

I am in the process of trying to send back the concentrator and portable but I am having a very hard time. I am now waiting for the finance company to return my phone call so I can return the items. This has to be the worst company I have ever dealt with.

The first machine was not powerful enough so we ordered a second. Just outside of our 30 day buy back window my stepfather passed away and Inogen is offering us no options.

They know that their customers are mostly terminal and would rather collect money from their family than offer some sort of buyback program or extended return option in these cases. It's disgusting honestly.

In general, Inogen portables are good but the cases have issues. The shoulder strap connects with a hook that easily disconnects. When that happens the machine falls on the floor, which can't be good. Please redesign the hook.

The new G5 comes with a handsome leather case, but the bottom padding is on the corners and so the machine will not sit upright. In addition, putting the canula connection on top of the machine means it's usually kinked.

The older machines with connection on the side were less susceptible. Does Inogen ever talk to users when it designs its equipment?

I just hung up with their customer service. Worst experience ever. I have no words for how bad these people were.

I was calling on behalf of my mother (and they knew it). First they asked for all my personal data. Then they wouldn't answer a simple question as to if I'll be able to order a concentrator using a foreign prescription.

When I told them that if they won't answer I'll just go ahead and order they told me it wasn't going to be possible. It took me 20 minutes to get that easy answer to a yes or no question.

Now they have my personal data. If I can retrace spam I receive to Inogen, I just want to let them know that I can and will sue them for that. Worst customer service ever. Stay away.

Inogen has been Amazing since the first conversation we had with Tom. We had been using the portable canister system. It was very inconvenient & bulky. Plus way too heavy for Marie to carry herself...which was keeping her from being as independent as she likes.

Tom answered all our ?'s & put our mind @ ease that Inogen 4 for the way for us to move forward w/ our traveling oxygen needs. We Love It!! Tom also has kept in contact to make sure everything is running smooth & we are all doing good.

Most companies these days MIA as soon as you've given them your money. Inogen is definitely a company that goes above & beyond in every area. Thank You to All.

I have had my Inogen One G4 for three years. First, I love the convenience, the size, the portability. Initially I only used it at night and when I flew on airplanes. After a recent COPD exacerbation, I am having to use it more frequently, especially when I exert myself.

It provides me with the O2 I need. Initially, I found the pulsating delivery a bit strange since I was used to continuous flow from an O2 tank. However, I now find it comforting, especially at night since between the hum of the unit and the pulse, it provides soothing white noise.

Fortunately, when I purchased the unit I bought the lifetime warranty. I say fortunately, because I have had to have it replaced numerous times because of various issues.

Sometimes it's been an issue with overheating; sometimes it's been a problem with alarms going off for no reason while I sleep; once it just totally stopped working; once it became very loud, and once the metal nipple broke off.

The good news is that Inogen has always agreed to replace it. Usually, it is overnighted so I have a functioning unit very quickly. Initially Inogen used UPS which delivered the replacement and immediately picked up the returning unit in the same visit.

UPS always provided me with a date and a delivery time window which made it easy to know when the unit was arriving. Additionally, UPS has an app that allows you to follow your delivery.

Recently Inogen has switched to FedEx which is not nearly so responsive. They only provide a delivery day but no time, so I have been stuck waiting.

Also, they do not take the returning unit at the same time and it's usually a couple of days later, but they do not provide a day or time, so I've missed the pickup sometimes.

Another issue, is that when I have called, the customer service person, until recently, did not provide any tips to trouble shoot, but immediately recommended a switch out.

This last time, however, when my unit was overheating, I had a great customer service person who walked me through some steps to trouble shoot. In the end, she had me press the + while the unit was off, plugged in and had no battery attached.

From the readout, she was able to ascertain that indeed my unit was overheating. After some discussion with her supervisors, given how frequently my unit had to be changed out for a reconditioned unit, she had a brand new unit sent to me.

Additionally, when I told her about my issue with FedEx and their pickup service, she emailed me a shipping label, so once I got the new unit I was immediately able to take the return to a nearby FedEx office.

Bottom line, I really like my unit when it works. If I didn't have the lifetime warranty, I would be very upset.

Finally, I recently had to replace the filter screen which I had lost. I didn't mind the price of the replacement ($12.00 for a piece that probably cost $2.00 to manufacture), but the $9.00 shipping was ridiculous for such a small, light piece.

The Sales person whose name doesn't come to mind at the moment unfortunately was excellent, came across as a very caring person determined to do the best for me.

Have two problems however, was given to understand that this machine is quiet whereas in fact I find it a little noisy and would not be able to use it at a show for example as it would disturb others sitting near me.

The second problem I have is with the Cannula, have finally found one that fits better in my nose and is soft, however most of the Cannula tubes are thick and a little too long and therefore unable to fit neatly in the pocket provided. Perhaps a larger pocket could be provided?
