An oxygen concentrator works much like a window air conditioning unit: it takes in air, modifies it and delivers it in a new form.
An oxygen concentrator takes in air and purifies it for use by people requiring medical oxygen due to low oxygen levels in their blood.
It works by:
1.Taking in air from its surroundings
2.Compressing air, while the cooling mechanism keeps the concentrator from overheating.
3.Removing nitrogen from the air via filter and sieve beds
4.Adjusting delivery settings with an electronic interface
5.Delivering the purified oxygen via a nasal cannula or mask
