The gas discharged from the oxygen concentrator is not harmful.
Oxygen concentrator is directly from the air separation of oxygen, for the physical principle, without any chemical changes, the exclusion of the gas is mainly nitrogen, oxygen in the air accounted for 78% of the nitrogen, in fact, the air we breathe every day, oxygen accounted for about 20% of the nitrogen is harmless to the human body. So it will not bring harm to people.
Home oxygen generator produced by the medical oxygen purity of 93% ± 3, not pure oxygen, the export pressure of 0.04-0.05MPa. Oxygen from the machine export delivery to the head of the oxygen absorbing tube there is a part of the pressure loss, so it is very safe. However, the size of the oxygen intake, the length of oxygen intake time varies from person to person, subject to the oxygen intake of the person who feels good.

Electronic oxygen generator
Electronic oxygen generator in the drugstore is more common, the use of oxygen in the air in the solution of oxidation and reduction of precipitation process, and therefore will not be like electrolysis of water to produce oxygen as dangerous as hydrogen. The whole machine runs more quietly, but these products in the handling and use of the process requirements are very strict, never allowed to tilt and inverted, otherwise its solution will flow into the oxygen tube into the nasal cavity of the user causing serious damage.
Molecular sieve oxygen concentrator
Molecular sieve oxygen concentrator is a kind of advanced gas separation technology, the physical method (PSA method) extracts the oxygen directly from the air, which is ready to use, fresh and natural, the maximum pressure of oxygen is 0.2~0.3MPa (i.e., 2~3 kilograms), and there is no danger of high-pressure explosion.
Chemical oxygen generator
It is the use of reasonable pharmaceutical formulations, used in specific occasions, can indeed meet the urgent need of some consumers. However, due to the equipment is simple, operation trouble, the use of high cost, each time the oxygen need to invest a certain amount of money, can not be used continuously and many other defects are not adapted to the family oxygen therapy.
Oxygen-enriched membrane oxygen concentrator
This oxygen concentrator adopts the way of membrane oxygen production, through the membrane of the nitrogen molecules in the air filtration, to achieve the concentration of 30% of the exported oxygen, has the advantages of small volume, small power consumption. However, this oxygen generator produces 30% oxygen concentration, which can be used for long-term oxygen therapy and health care, while the first aid required in severe hypoxia can only be used for medical high concentration oxygen.
