What is a 5L Oxygen Concentrator?
A 5L oxygen concentrator is a medical device that provides a continuous supply of oxygen at a flow rate of 1–5 litres per minute. It takes in room air, removes nitrogen through filters and molecular sieves, and delivers up to 93% pure oxygen. Unlike oxygen cylinders, it does not require frequent refilling, making it ideal for long-term therapy.
