I regularly inhale warm steam, including to the upper respiratory tract with the help of the nasal mask that comes with the device. This is especially important during the flu season when the risk of getting sick is higher. I have managed to stay exceptionally healthy for the last three training seasons. Using WellO2 has been one of my key preventative ways to avoid getting sick.

I now take my WellO2 device with me everywhere in the world. I’ve had it for about a year. No matter the temperature or humidity – if my voice feels a bit dry or rough, just a few minutes with this device, and I’m singing like a Vienna Boys' Choir member.

I was surprised by how pleasant it felt to breathe with the WellO2 device. The nasal mask, in particular, was very helpful. I find the device easy and comfortable to use.

While running, I noticed how much easier breathing felt. The improvement in oxygen intake becomes evident when you don’t get out of breath as quickly.

I would recommend the WellO2 device to anyone who breathes, but especially to those who experience respiratory issues or frequently get sick. It’s also great for families with children!

I have noticed that my breathing has overall become stronger and clearer with the use of WellO2. I use it at least twice a day, in the morning and evening. WellO2 not only exercises the lungs but also all the other muscles needed for voice production, including the side and abdominal muscles. Considering the good results, the time investment is not very much. I always have it with me on tours.

I've slept better since I started using the device, and I also feel more refreshed. I used to be ashamed to constantly clear my throat around people, but now I feel relieved. It’s a good device, I certainly give it a ten out of ten. Good and easy!

I bought my WellO2 and I noticed a significant improvement in my breathing after the very first use. Back when I was a professional athlete, I even took my WellO2 with me on competition trips.

In my opinion, WellO2 is suitable for everyone. It helps your body relax in the evenings, and most importantly, it’s great for easing symptoms when a cold strikes, reducing the severity of aftereffects compared to not using WellO2.

Using the nasal mask that comes with the device in the evening clears my nose completely, making it much easier to go to sleep. Since starting with WellO2, I haven’t needed to use nasal drops anymore.

WellO2 training has greatly helped my instrument playing. It has opened up my airways, relaxed my muscles, and activated my intercostal muscles. Additionally, it has made my breathing deeper, which allows for a more relaxed and resonant sound from my instrument.

We’ve partnered with WellO2 since 2017. Our members have used the device with great results, reporting easier breathing and clear benefits.

In 2020, we began a commercial collaboration and granted the right to use our logo. WellO2 has since produced scientific evidence supporting the device’s effectiveness.

We trust in the product and hope it will help people with respiratory conditions internationally. As a member of EFA, we continue to advocate for better breathing for all.
