Home oxygen concentrators can be purchased at your local pharmacy or hospital.
When you decide to buy, you need to confirm the after-sale warranty of the product with the merchant personally. After purchase, be sure to carefully read the instruction manual before use.

Personal advice or go to the physical store to buy more assured, now the brand is a variety of, due to the regulation of not strict a lot of health care oxygen side focus on publicity large flow and ignore the oxygen concentration. Pure imported only 5 liters of medical oxygen concentrator.

How to choose a home oxygen concentrator?
1, look at the oxygen generator oxygen production method. Oxygen generator oxygen way there are three are molecular sieve principle, polymer oxygen-rich membrane principle and chemical reaction oxygen principle. Only molecular sieve oxygen generator is the only mature oxygen generator, the only oxygen generator with international and national standards.
2, see the size of the oxygen concentration. The size of the oxygen concentration is to determine the oxygen concentrator good or bad one of the important factors, a good quality oxygen concentrator it should be able to stabilize the oxygen concentration in 90%.
3, see the oxygen concentrator core components: molecular sieve and air compressor. Air compressor, need to use high efficiency, oil-free compressor, if the use of oil compressor will contaminate the oxygen, and harmful to the body, and a good oil-free compressor, requires strong performance, good heat dissipation performance, and running noise, and to ensure that the service life is long.
