Flutter Valve Device for Lungs, Breathing Exercise Device, Adjustable Resistance Breathing Trainer for Natural Mucus(Strong)

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.

I had fewer expectations from this but have a good impression of this product. Well built product and works great for the exercise and drug-free mucus removal needs. My 2 cents below: Pros: - Works great as a exercise device and mucus removal while being drug-free - Has an adjustable resistance dial to control the intensity as per the needs - Easy to use - Works without any battery - Very small in size and portable if you want to take it anywhere with you - Seems very durable Cons: - Not the most reasonably priced but would recommend for the quality and functionality

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 bought this oscillating breathing device to help clear congestion when my allergies act up and I’m really glad I did. After a week of using it twice a day I could breathe easier and my chest felt lighter. The device is compact and simple to clean so I keep it by my nightstand. It is very easy to use and send it would last for a long time. For what I paid, it seems like a smart, effective tool for maintaining clear airways and good value for money.

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.

REVISED: THE COMPANY REACHED OUT TO ME (AFTER AMAZON 30 DAY REFUND POLICY EXPIRED). THEY WORKED WITH ME TO HELP ME UNDERSTAND MY DEVICE AND HOW TO USE IT, PLUS THEY SENT A REPLACEMENT. THEY WERE VERY PRO-ACTIVE IN COMMUNICATING UNITL I WAS SATISFIED. THE PRODUCT IS A LITTLE TEMPER MENTAL TO RE ACTIVATE AFTER CLEANING, BUT IT DEFINITELY IMPROVES MY LUNG CAPACITY. OLD REVIEW: " Very discouraging. It worked for less than a month. I neglected to return it, because I kept thinking I was doing something wrong/ After cleaning, could never get the rocker on "just right", and barely get any vibration at all. For the money, it should last longer. I can tell a difference in my lung function since it quit working. So it was helping, as long as it worked."
