About Oxygen Concentrators
An oxygen concentrator provides a handy way to clear the air of harmful substances. Products available for use in the home are typically portable, so you can transport them easily when you travel. Oxygen concentrators filter dust, bacteria, and viruses from the air, and supply a rich source of oxygen. They come with breathing apparatus and some models have batteries that last up to eight hours. You can find oxygen concentrators in hospitals where they help to treat patients that require high levels of oxygen. However, products for the home are not intended to treat serious diseases. These machines are available on eBay in a range of sizes and designs. Many come with a case or handle that makes them easy to carry. Make sure that the machine has a power adapter and cable, and a car charger, if you want to travel with the device. Look for products that contain instructions about how to use it safely.
