Meet the AirPhysio breathing trainer: a lung trainer that doubles as a mucus removal device that can improve your breathing and clear the airways. It helps push the mucus up the airway walls and out of your body. AirPhysio also increases your lung capacity, making it ideal for people dealing with asthma and bronchiectasis.
The device should be used for about 5 minutes, a couple of times a day. You can find out more about it here.
