アカペラ呼吸装置、フラッターバルブ、肺用呼吸エクササイズデバイス – 医療グレードの素材、効果的な粘液クリアランスと呼吸トレーニングのための調節可能な抵抗

Found this after my doctor recommended it to assist with my lung function. Easy to use. Good video on how to clean. Clear instructions and a good value. Well Designed an made with high quality.

The AiraVentus Flutter Valve has really help with my breathing over time. I particularly like the adjustable resistance which allowed me to start at an easier setting and then allowed me to move up as my breathing improved. Also, unlike other valves, it is very easy to disassemble and clean in just a few minutes. It has been very effective in helping me to loosen and clear mucus. Definitely a high value product.

Great product - I feel better even after a few days of using it. Helped clear up my cough. Cleaning it is very easy too.

This flutter valve device works great. I use it 2-3 times a day to help break up mucus and increase the inhalation and exhalation of my lungs. It has really helped my breathing and reduced my COPD symptoms. It’s very easy to use and is a super form of breathing exerciser.

I received my Flutter Valve Device yesterday and immediately started using it. It was recommended by a relative who has the same model. I used mine as soon as I received it. And again today a couple times so far. I can tell it's doing what it is supposed to. I am already bringing up flem and and mucus. I highly recommend this product. Thank you.
