Airlife Volumetric Incentive Spirometers, 4,000 Ml - 1 Each

I bought this for my wife, and it has helped her immensely during her recovery. The large capacity is great, and she’s been more motivated to do her exercises with this spirometer.

This spirometer is a must-have for anyone recovering from lung issues. It's very user-friendly and durable. I appreciate the lack of a 1-way valve as it simplifies cleaning and maintenance.

I’ve found the Airlife spirometer very effective after my respiratory issue. The 4,000 ml capacity is perfect for ensuring I’m working hard during my breathing exercises.

After my surgery, I needed something to help with my lung function, and this spirometer did the trick! It's simple, effective, and has made a noticeable difference in my recovery process.

The Airlife spirometer is lightweight and portable, which makes it easy to take around the house. It's been really helpful for my respiratory therapy exercises!
