Oxygen concentrator

An oxygen concentrator is a medical device that provides a steady supply of concentrated oxygen from the air you breathe. It works by drawing in ambient air, which contains about 21% oxygen, and removing nitrogen and other gases through a process called filtration. The device then delivers a higher percentage of oxygen directly to the user through a nasal cannula or mask. It is commonly used by individuals with respiratory conditions such as COPD or other illnesses requiring supplemental oxygen, offering a portable, noise-reduced, and maintenance-friendly alternative to oxygen cylinders.
