Flutter Valve, Breathing Exercise Device for Lungs, Adjustable Resistance Natural Mucus Clearance, Portable Lung Exerciser Device | Breathing Trainer

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.

This product works well and is very easy to use. I searched through many similar products and this product had the best value and is very durable.

I bought this breathing exerciser hoping to support my lung strength and overall breathing comfort. It works great. It’s small and portable so I keep it on my desk and use it daily while watching TV or reading. For what I paid it seems like solid value, and I appreciate how simple it is to use. It has quietly become part of my wellness routine.

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.

Not bad actually helped out loosening some mucus. You pretty much have to blow into the device and it makes a good amount of vibration in your throat. Product looks well made will continue to use.

Have been using this for over a couple of weeks now. Simple to use and clean, compact, noticeable improvements in breathing, and clear lungs.

Perfect size for a senior to use and having two mouthpieces to make cleaning a breeze is a bonus. Easy to use design and works well.

Could not get it to "flutter". Got 2 and will be returning the 2nd. The top part seems to disconnect when trying to use, and I needed to hold it together. Was difficult to use, and I couldn't get it to function.
