Surprisingly Good

As a long-time user of various oxygen monitoring devices, I've had the pleasure of experiencing Wellue’s SleepU blood oxygen monitor in the past. It has been an exceptional device that I continue to use to this day. However, fate took an unfortunate turn when my previous oxygen concentrator malfunctioned a few weeks ago, leaving me in need of a replacement. It was fortuitous that during my search for a new concentrator, I found Wellue not only sold oxygen concentrators but also had a discount offer. What's more, they had an additional deal where, for a mere additional 40 bucks, I could acquire an O2RING oxygen monitor valued at over 140 bucks. This compelling offer led me to purchase this oxygen concentrator along with the O2RING blood oxygen monitor. Upon receiving the order, I immediately noticed the enhanced quality of this oxygen concentrator compared to my previous device. Firstly, this concentrator felt lighter and smaller without compromising on its sturdiness. Secondly, this concentrator operates at a lower noise level, offering a quieter experience. Overall, I am extremely satisfied with my purchase and look forward to continued reliability and performance from these exceptional products.

Great machine! Exceptional price!

This machine is a great machine and very reasonably priced! I received it in a timely manner as well! I ordered the O2 monitor ring with it too, and this little ring is truly a life saver! Before I went on oxygen it would alert me to low levels and actually vibrate and wake me up. I had a heart attack because my O2 levels were too low at night and after that my children bought me the ring. It saved my life until I was medically approved for O2 therapy! I don’t sleep without it now!

Love it

I use this concentrator with my CPAP, which already includes a humidifier. So I removed the water bottle from the concentrator. It works well and contributes to a further reduction in noise.

My First O2 Concentrator

I wasn't sure how much supplemental O2 would improve my SpO2 numbers, and didn't want to spend a huge amount to try out the concept. I've been using Wellue Checkme O2Max device for three years to monitor my levels during the night while I'm on a CPAP machine, and have found it reliable and easy to use. There are many low-priced O2 Concentrators on the market, but I wasn't familar with any of the suppliers. I was happy to discover that Wellue sold one, and even happier about the amount of information Wellue provides about it online. The concentrator arrived promptly, was easy to set up, and worked perfectly right out of the box. I've been using the concentrator for a week, and while I'm sure patient responses vary widely, for myself, I can say that the improvement in my SpO2 numbers, as reported by my O2Max device, exceeds my most optimistic expectations. I find the unit to be acceptably quiet, it's totally simple to operate. It is clean-looking and seems well-made. It is also heavy enough that I wouldn't want to carry it around very much. It's about as big and heavy as a pretty sturdy sewing machine. It rolls very easily on its casters, though. I know I could have bought a smaller, lighter, possibly quieter, battery and AC powered concentrator that could easily be taken traveling, but it would have cost six times as much as the Wellue. Maybe someday, but for now, the Wellue O2 concentrator is exactly what I was looking for and I consider it a real bargain at its price. If you're tempted to buy one of the other lower-priced O2 concentrators, be sure to carefully compare its specs to the Wellue unit, especially with regard to O2 percentages at different flow rates. I'm not an expert--these are just my observations after using the Wellue O2 concentrator for a week. As you can tell, I'm very happy with it so far.
