Mucus Clearing Lung Exerciser Device

The product is a respiratory health device designed to aid in lung expansion and mucus removal. It features a steel ball that creates resistance to airflow, exercising exhalation muscles and strengthening the lungs. The device also generates air pressure vibrations to loosen airway mucus, which can then be removed by coughing. The product includes three different sizes of balls, with larger balls providing greater exhalation resistance and better workout results. The device is small and portable, allowing for lung exercise anytime and anywhere without complex steps or venues. It is recommended to use the device 1-2 times a day for 5-10 minutes each time for the best exercise effect. The product is designed for unisex use and is not discontinued by the manufacturer.
