Flutter Valve Breathing Exercise Device for Lungs, Portable Lung Exerciser & Mucus Clearance Device, Adjustable Resistance for Mucus Removal

I’ve been using the breathing trainer for a few weeks now, and I can honestly say it’s made a noticeable difference in both my lung capacity and overall breathing control. At first, it felt a little challenging to get used to, but that’s the point—it provides just the right amount of resistance to strengthen your respiratory muscles. The design is compact, lightweight, and easy to carry, so I can use it at home, during breaks at work, or even while traveling. Cleaning is simple, which I appreciate, and the adjustable resistance levels mean I can gradually increase the intensity as my lungs get stronger. Since starting, I’ve noticed improved stamina during workouts, less shortness of breath when climbing stairs, and even better relaxation when I pair it with deep breathing exercises. It’s a great tool not just for athletes, but also for anyone wanting to improve lung health, manage stress, or support recovery after illness. Overall, I highly recommend this breathing trainer—it’s a small investment with big benefits for your health and fitness.

I’m very impressed with this lung exerciser device. It’s simple to use, lightweight, and well built. After just a short time of regular use, I noticed an improvement in my breathing capacity and lung strength. The adjustable resistance feature is a big plus—it allows you to start at an easy level and gradually challenge yourself as you progress. The device is also easy to clean and small enough to carry around, so I can keep up with my exercises at home or on the go. It’s a great tool for anyone looking to strengthen their lungs, improve stamina, or support recovery. Definitely worth it and highly recommended!

A pulmonologist recommended this for lung exercise. Unfortunately the intended target does not have enough sustained breath to get the benefit. At least we didn't buy it from the medical center supply where it was $80 and private pay! Our respiratory tech did note the price, quality, etc, and may be telling others to get them from Amazon.

I purchased this lung exerciser to help improve my breathing, and it has been a great addition to my routine. The device is compact and easy to use, which makes it convenient to take anywhere. I really appreciate the three different ball sizes, as they allow me to gradually increase resistance as my lung strength improves. What I like most is how straightforward it is—no complicated setup, just a simple and effective way to practice controlled breathing. I usually use it once or twice a day for about 5-10 minutes, and it has definitely made me more mindful of my breathing patterns. The small, portable design means I can use it at home or even while traveling, and it doesn’t feel bulky at all. I also noticed that the varying resistance levels give me a sense of progress, which keeps me motivated. Overall, it’s a great tool for anyone looking to work on lung capacity or breathing technique.

Works great and the quality is awesome

i just want to say this. it works if you use it.

Highly recommend. Easy to wash, appears unbreakable, easy to use and is compact size. Quiet to use, I am not disturbing anyone else in the room when I use it. Dishwasher safe is also a plus. After a month of use I truly believe my breathing has improved. The different levels of resistance is very beneficial. If you are undecided give it a try.

This lung expansion and exercise device doesn’t need any additional power. There’s no need for batteries or charging. The device all comes apart for easy cleaning so it can be sanitized. There’s three different size metal balls. This makes it easy for continued use while building up Breathing stamina. The mouthpiece is square piece that is angled so that the mouse easily and tightly fits around it. This also has a small eyelet on it. This eyelet makes it possible to secure it to a cord that can be that attached to something else so that doesn’t get lost. This comes in handy when using this for extended periods of time so that it doesn’t easily get lost or misplaced.
