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

It works really well! After using it, I can feel my chest open up and breathing becomes easier right away. It’s simple to use and fits easily into my routine. Overall, it’s an excellent tool and does exactly what it’s supposed to do.

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.

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 have had this for about a week now and use it diligently about 3x’s a day. I have to say it is not quite 15mins but I try to use it extra. I have noticed a difference in my lungs being able to take deeper breathes and hold it longer after using this for just a short period of time. On a different note if the smallest ball feels ‘too easy’ don’t hesitate to start with the medium ball or at least try it to see if you can do it. I have moved up by the fourth day. I wash it every night before bed and let it air dry. Great product compared to the ball contraption my dad used in the hospital.

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

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!

“The size was just right for handheld use. It’s compact enough to keep nearby without taking up much space, but still large enough to hold comfortably during breathing exercises. It felt lightweight and easy to use, and the adjustable resistance made it feel practical for regular daily sessions. You must use it daily, 3 Times a day. After 2 weeks i noticed a measurable difference.

quick arrival, great product, recommended by the Pulmonology Physician. NON INSURANCE COVERAGE, BEST PRICE HERE ON AMAZON.
