No: Our lungs are self-cleaning, unless we put too much toxic stuff into them (such as smoking), or unless they have a defect (such as cystic fibrosis), or unless there is some other infectious or scarring disease. Somebody out there may be trying to sell an "oxygen wash" but it is unnatural and unneeded.
