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.
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.
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.
I checked the package against what was advertised on the website.
After several years of relying on my old POC for sleep therapy, I knew it was time for an upgrade. Finding a new concentrator that fit my budget was a priority, and Wellue's POC definitely delivered on exceptional value. Right away, I was impressed by how much smaller and lighter it is compared to my old model. This makes a huge difference for everyday use and travel! I'm very satisfied with my purchase and excited about the newfound comfort and portability it offers.
