A portable oxygen generator is a device that separates oxygen from the air, allowing you to breathe oxygen when needed. Portable oxygen generators can run on either AC or DC power and can be recharged from either power source. Charging the battery draws in air, separates the oxygen from the remaining air, and delivers it back into your lungs at the right rate. Some oxygen generators feature both continuous flow and pulse-delivery settings. Home oxygen generators are devices that convert air into oxygen, allowing you to breathe more easily. Operating on AC power, they are suitable for use with a single machine version for home use or in a single location. The machine draws air through the intake duct. The air then passes through a filter that captures dust and small, unwanted particles before entering the oxygen separation system. The oxygen is then released through pipes and gardens in an appropriate amount.

A continuous-flow oxygen generator is one that delivers oxygen continuously, but a pulsed oxygen generator delivers oxygen based on your breathing. This is because a pulsed oxygen generator often has a sensor to detect your breathing.

The suitable temperature range for using our oxygen generator is -20℃~60℃. Cold weather conditions may affect the battery life of the portable oxygen generator.

Yes, all of our oxygen generators are available 24/7, even running while you sleep.

All of our oxygen machines, both home and portable, come with a 1-year warranty, with the exception of used oxygen machines and accessories.
