Olive Oxygen Concentrator O2 Concentrator Travel Home Oxygen Concentrator Medical 3 Liter 5L Battery Portable Oxygen Concentrator

Oxygen is a basic human need. We cannot survive without it. The air we breathe contains about 21% oxygen. That's enough for most people with healthy lungs, but for some people with certain health conditions whose lung function is impaired, the amount of oxygen they get through normal breathing isn't enough. The oxygen concentrator separates oxygen molecules and nitrogen molecules from each other to produce high-concentration oxygen. Captures nitrogen from compressed air and provides supplemental oxygen by compressing the room air to 4 atmospheres. This concentrates the oxygen in the compressed air without adding chemicals.
