🍄 What is an oxygen concentrator?
An oxygen concentrator is a type of medical device used for delivering oxygen to individuals with breathing-related disorders. Individuals whose oxygen concentration in their blood is lower than normal often require an oxygen concentrator to replace that oxygen.

Oxygen concentrator generates oxygen for individuals with breathing-related disorders by filtering the surrounding air into purified medical grade oxygen and deliver to the patient.

How does an oxygen concentrator work?
Think of an oxygen concentrator as a window air conditioner — it takes air in, changes it, and delivers it in a different form. The oxygen concentrator takes air in and purifies it for use by individuals who require medical oxygen because of low levels of oxygen in their blood.
