I've had it for a week and it broke already

I honestly had high expectations when I placed my order and was looking forward to receiving the product. However, when I noticed that the product description on my receipt was different from what I believed I had ordered, I contacted the company simply to ask for clarification. Instead of receiving a clear explanation, my order was canceled without my request or consent. Unfortunately, I was never given a reason for the cancellation. I was genuinely disappointed because I only wanted to make sure I was receiving the correct product. I hope the company can improve its communication with customers in situations like this.

We're sorry to hear about your experience. We've checked our records and can't find an order matching your details, so we believe this purchase may have been made with another company. If you did order from us, please contact us at 877-303-9289 with your order number and we'll gladly look into it.

Received a car/automobile charger. I need a home charger. Unable to use my O2
Response from Oxygen Concentrator StoreOct 6, 2026
Thank you for sharing your feedback, and we're sorry for the frustration. We know how important it is to keep your oxygen equipment charged and ready when you need it. Our records show the order placed with our sales team was for a car charger, which is what was shipped. When we followed up by phone, we offered to switch you to a home charger and went over the price difference. At that time, you let us know you'd prefer to keep charging your unit in the car. If anything has changed, or if a home charger would make things easier, we'd be glad to help. Please contact us at 877-303-9289.

You sent a cheap, hard plastic mask tyat ws collasted on one side and had multiple grimps in the tubing. It was unusable. Lawrence Howell

Thank you for following up, Lawrence, and again we are sorry the mask arrived collapsed on one side and with kinks in the tubing. That is not the quality you should receive, and we want to make it right. Our customer service manager has tried reaching you by voicemail on both numbers and by email. Please give us a call at 877-303-9289 whenever it is convenient, and we will get a replacement sorted out for you right away.

I was told that it would last 2 to 4 hours on a full charge. I’m lucky to get 1 hour and it never gets into the 90s.
Response from Oxygen Concentrator StoreSep 25, 2026
Hi Paul, Thank you for your feedback, and I'm sorry for the confusion about battery life. The 2 to 4-hour range applies to the lower settings. On setting 4 which is what you stated you are using, the battery is designed to run about 1 hour and 24 minutes, so the runtime you're seeing is in line with how the product works. We're sorry that wasn't made clear when you were given the estimate. If you have any other questions, do not hesitate to give us a call at 877-303-9289.

Thank you for taking the time to share your experience, and we're sorry to hear about your frustration. For health and safety reasons, masks are a non-returnable item. This is standard across the industry. We understand this wasn't clear to you at the time of purchase, and we apologize for any confusion caused during the ordering process. As a one-time courtesy, and not something we are able to offer as a general policy, we have already processed a refund for your masks which will be reflected in your account within seven business days. We hope this helped resolve the matter, and if you have any further questions, please feel free to call us at 877-303-9289.

The unit we were given originally was loud, we weren’t told it was air on demand, it only worked for 6 months, when I called about the problem, I was told it would arrive that Tuesday because Monday was a holiday, it came today, Saturday. What if that had been his only unit? And the worst! I’m told you send us a box and I have to return the unit in three days or I’m charged for the unit. Later, the paper work in the box said maybe, $15? Doesn’t matter, the idea that if it isn’t sent by a certain time or else is rude. Maybe one or two weeks, this is absurd. I dislike your company, I will discourage anyone from using your service and we certainly won’t again. Don’t think about sending us any sales info.

Thank you for taking the time to share your feedback in detail. We are sorry your experience fell short. We also want to clear up the return timeline, since we can see how it came across. The request to send the original unit back within a few business days is meant to be flexible, not a threat — if that window is ever too tight, a quick call or message to us is all it takes, and we work with you rather than default to a charge. We hear you that the wording didn't come across that way, and we're taking that feedback seriously. We'd genuinely like the chance to make this right. Please reach out to us directly at 877-303-9289.
Williams, P.
The new battery didn't last no longer than the battery I already had. It was fully changed.
Response from Oxygen Concentrator StoreAug 31, 2026
Thank you for sharing your feedback, Phyllis, and we are sorry to hear the new battery did not perform the way you expected. We understand how important dependable battery life is, and we want to help get this sorted out for you. The good news is that your batteries are fully under warranty. Our team has spoken with you about performing a battery recalibration, which often resolves this kind of issue, and if that does not do the trick, we will move forward from there. Please always feel free to call us first at 877-303-9289 anytime you need anything, and we will be glad to help. We are confident we can get this working the way it should. If you ever need anything else, feel free to reach out, we're here to help!
