Oxygen Concentrators

Oxygen Concentrator is a medical device that gives you extra oxygen. Air is made up of about 20% oxygen. An oxygen concentrator uses the sir in the atmosphere, filters it, and gives you air that is 87%-95% oxygen.
Your doctor may prescribe one for you if you have a health condition that causes your oxygen level to drop too low. At Medcialeshop portable oxygen concentrators are available, also known as a travel oxygen concentrator, which are smaller and lighter than the at-home version. Portable oxygen machines run on a rechargeable battery and tend to weigh between 2 and 20 pounds.
