How can I clean my lungs?

There is no scientific proof to methods available online to detox your lungs. Fortunately, Lungs are good at cleaning and repairing themselves unless there was any chronic damage done. You may follow some steps to keep the lungs healthy such as Quit smoking, avoid second-hand smoke, steer clear of pollution indoors & outside (Wear mask, use air purifiers), prevent lung infections (Hand washing, maintain distance from sick people, get flu/pneumonia vaccines), include anti oxidants in diet and do breathing exercises or any physical activity on regular basis.
