The difference between 1 liter and 2-liter oxygen generators is as follows.
1, the compression ratio of 1 liter oxygen generator is lower than that of 2 liter oxygen generator.
2. The oxygen concentration is different under the same conditions.
1 liter means that when the oxygen flow rate is 1 liter, the oxygen concentration is above 90%. When the oxygen flow rate is 2 liters, the oxygen concentration will be obviously less than 90%; 2 liter machine means that when the oxygen flow rate is 0.5~2 liters, the oxygen concentration can reach more than 90%.

Classification of working principle of oxygen generator
1, electronic oxygen generator
Electronic oxygen generator is commonly used in pharmacies, which uses the process of oxidation and reduction of oxygen in the air in solution, so it will not produce dangerous hydrogen like electrolysis of water to make oxygen.
The whole machine runs quietly, but the handling and use of such products are very strict, and it is absolutely not allowed to tilt or invert, otherwise its solution will flow into the oxygen delivery tube and spray into the nasal cavity, causing serious harm to users.
2. Molecular sieve oxygen generator
Molecular sieve oxygen generator is an advanced gas separation technology. Physical method (PSA method) directly extracts oxygen from the air, which is fresh and natural. The maximum oxygen pressure is 0.2 ~ 0.3 MPa (2 ~ 3 kg), and there is no danger of high-pressure explosion.
3. Medical oxygen generator
Adopting a reasonable drug formula and using it in specific occasions can meet the urgent needs of some consumers. However, because the equipment is simple, the operation is troublesome, and the use cost is high, each oxygen inhalation needs a certain fee, and it cannot be used continuously, so it is not suitable for home oxygen therapy.
4. Oxygen-enriched membrane oxygen generator
This kind of oxygen-making machine adopts membrane oxygen-making mode, and the nitrogen molecules in the air are filtered by membrane, and the oxygen concentration at the outlet reaches 30%, which has the advantages of small volume and low power consumption. However, the machine adopting this oxygen-making method produces 30% oxygen, which can be used for oxygen therapy and health care.
