Break free from the limitations of traditional oxygen therapy. Wellue combines the power of a portable oxygen concentrator (POC) with the precision of a continuous O2Ring monitor.
Many users rely solely on their POC settings. However, a continuous oxygen monitor provides a crucial additional tool: real-time SpO2 (blood oxygen level) readings and fluctuations.
By seeing how your blood oxygen level responds to different POC settings, you can adjust them for maximum effectiveness. This can lead to a more comfortable and secure oxygen therapy experience.
Your body’s oxygen needs change throughout the day. This makes it difficult to know if the flow setting of your portable oxygen concentrator (POC) is always optimal for you. Acting as a copilot for POC, Wellue’s O2Ring changes the game.
Imagine setting your POC level 2 intitially. The O2Ring continuously tracks your blood oxygen level in real-time. It tells if your body’s oxygen level is high enough. If the O2Ring reading is low, you can adjust up POC settings.
It’s like driving your car without a dashboard to use POC without O2Ring.

I am very pleased with my oxygen concentrator! I had trouble with the big oxygen tanks and this is small and easy to operate. I am 95 and it works great!
Very happy with concentrator and it works as I had hoped--frees me up to go more places and do more things
I am so glad to be unencumbered with a bulky tank! It's so easy to just turn it on and go. I changed the strap to something more comfortable.
I looked at so many portable concentrators and weighed all the pluses and minuses. I am so glad that I opted for this portable concentrator.
The POC is very light and comes with a carrying bag. It’s so easy to carry and just go!
The portable oxygen concentrator is convenient and has an attractive design. It allows me to go out for more than 3 hours. I was able to set the flow at 1 while seated in the car, and it lasted for about 5 hours. Now, I feel safer because I can plug the unit into our truck while driving, which saves on the battery. This way, I can continue my oxygen therapy while we are traveling.
I have had this portable oxygen concentrator for several days. It is so light and I often forget that I have it on. I only use it when I go outside since I have a large compressor at home. It does have a warning beep to remind me of some problems like low battery and no breath. This important. It has been a wonderful change for my breathing.
After I was diagnosed with heart failure and supplemental oxygen, I started researching which oxygen concentrator I should buy. The top of the line, the Inogen G5, was quite expensive, not covered by my medicare (they called it a luxury, but I decided it was worth it.) With dual batteries and a lifetime warranty, it cost me $3800. I had several problems after 18 months of perfect use, and decided I needed a backup because even though Inogen fixed every problem under the warranty, going back to the tanks wasn’t an option. The other top of the line was the Caire Freestyle, which I purchased for $2600. I also bought a refurbished SimplyGo unit for $1400 that worked great for a year and a half, but finally gave up the ghost after the warranty was ended, of course. I am extremely fortunate to be in a position to be able to afford purchasing multiple machines, but to me, it’s worth it. I have been using the Wellue ring to monitor my oxygen levels at night for almost two years and I am impressed with its reliability, so when I found that they were selling an oxygen concentrator I decided to try it to replace the refurbished unit that stopped working. I rotate machines so I am very familiar with how they each operate. I have been told that my Inogen and Caire machines are the best ones available. Having used them both over a couple of years, this new machine from Wellue is significantly smaller, lighter, and quieter than the Caire, is smaller and lighter than the Inogen, and half the price of either of them. The weakness of the Wellue concentrator is in the battery life. I need a pulse setting of 4, and the battery life, for the single battery is about 1.5 hours. That’s fine for my day to day use around the house, but going to lunch, for example, requires taking a second battery, and even then, I have to be careful. Both the Inogen and the Caire have double batteries that last 4-5 hours. It does have a car charger, which helps, but if the Wellue would increase the battery life, I would say that, in my experience, it was better than both the Caire Freestyle and the Inogen G5 I have, and at half the cost. (One other huge advantage for both the Inogen and the Wellue units is that the sieves are customer replaceable, without having to send the unit in for maintenance.)
The Portable Oxygen Concentrator we purchased for our mom has been a great solution for her! She found it difficult to manage oxygen tanks due to their weight, the challenge of changing the regulator, and the limited oxygen capacity they provided. The concentrator has relieved these concerns for her and brought her peace of mind. It is lightweight and easy for her to handle, allowing her to move around more comfortably. Unlike the tanks, which didn't hold enough oxygen for a full day of activities, the concentrator provides oxygen of high concentration, ensuring she has enough oxygen for meals, doctor's appointments, and other daily tasks. The convenience of simply plugging it in to recharge adds to its user-friendly nature. We are relieved to see how much it has improved her quality of life.
I checked the package against what was advertised on the website.
The device is extremely easy to set up and use. Being able to plug into a wall outlet and operate is very convenient when you need the unit longer than a couple hours: such as attending a social function. The customer service is very professional as well.
