Two Steps To Remove The Battery.
3. Dual Oxygen Delivery Modes
This device has 2 oxygen delivery modes: Pulse Mode delivers oxygen by sensing the user's breathing rhythm, while Continuous Flow supplies oxygen at a fixed frequency. The 2 modes switch automatically according to users’ breathing patterns, which is suitable for a broad range of people.
The dual-mode oxygen concentrator NT-02 is an innovative and effective way to provide oxygen therapy to patients. Compared with the only continuous flow oxygen concentrators, the dual-mode NT-02 ✅saves more battery power, which means users can use it longer without draining their batteries. The dual-mode oxygen concentrator can also produce oxygen for three seconds ✅without detecting the user's breathing, compared with only a pulse flow oxygen concentrator, it is easier to obtain oxygen for users with shortness of breath or shallow breathing.
4. Stable Oxygen Concentration
This oxygen machine outputs oxygen at a high and constant concentration of 93±3%. The flow rate is easily adjustable between 1-5L/min, allowing you to regulate the amount of oxygen you receive based on your needs.
5. Clean Oxygen Supplement
Our home oxygen concentrator features a high-quality CECA molecular sieve and undergoes a rigorous self-filtration process to purify oxygen before being finally delivered to users, ensuring every breath you take is pure and clean. 2 filter pads are included for easy replacement.

6. Restful Oxygen Therapy
An auto shutdown timer on the oxygen concentrator machine allows you to set a time interval between 1-240min. Moreover, it can be conveniently used overnight while plugged in, which is ideal for anyone requiring oxygen therapy during sleep.
7. Intelligent Alert System
Our oxygen generator has an advanced built-in alert system, providing real-time alerts for low battery, no breath being detected, low oxygen concentration, or high temp. This offers peace of mind to stay in control of your oxygen therapy process.
