PowerLung products have been proven in independent studies to work when used properly and regularly.

Because you control how and when you use your PowerLung, we cannot guarantee the results you will receive. However, PowerLung will increase your ability to breathe deeper and easier with more stamina when used in a consistent program of exercise and as long as your lungs are reasonably healthy. PowerLung is designed to exercise the muscles your body uses to breathe with, but cannot repair lung damage caused by Asthma, COPC, Emphysema and other lung problems. For lung disease issues, please consult with your physician as to whether breathing exercise can be beneficial.
