The noise control is so good that you can barely hear it when using it at night and it doesn't affect the quality of your sleep at all. Intelligent display is clear and easy to understand, easy to operate, the elderly and children can easily get started, truly humanized design.

This home oxygen concentrator is really the guardian of family health, 1-9L of oxygen release perfectly meets different needs, and you feel like breathing more smoothly every day you use it.

This oxygen concentrator is a true work of art – both visually appealing and incredibly functional. The 1-9L output is impressive, and the low noise level is a huge plus.

The battery lasts a long time, so you can take it out with you for a long time, and the battery is of good quality, so you don't have to worry about it going bad in a short period of time.

I wanted an oxygen concentrator that I could take on the go at all times, and after much research I chose this item, which is lightweight enough for on-the-go, while making enough oxygen for use.
