Incentive Spirometer for Adult Lung Trainer Breathing Exerciser Respiratory Strengthener Device -5000ml Volume

Bought for my mom because she had bronchitis. This wasn’t too hard for her to use and it helped her get better. 👍🏻🙏

The media could not be loaded. This spirometer is perfect for exercising inhalation! It’s very lightweight, and the handle design is very easy and comfortable to hold. So I can easily hold it and practice anytime anywhere. I also really like the design with the sad and happy faces, which lets me know if I’m using too much force (or not enough)
