This is the all-natural and drug-free device that helps loosen mucus in the throat and lungs. Using Oscillating Positive Expiratory Pressure (OPEP) therapy, it’s placed in your mouth like an asthma inhaler and contains a stainless steel ball that vibrates as you breathe in and out. The ball’s vibration is recycled back into your airways, helping loosen mucus as you inhale and exhale and enabling you to expel it through coughing. Ideal for helping with respiratory conditions such as asthma, bronchiectasis, bronchitis, COPD, cystic fibrosis, and chest colds, the device provides relief naturally without drugs, chemicals, or uncomfortable irrigation systems. An optional filter (sold below) enables multiple users.
