General Product Questions
Do I need a prescription to buy a portable oxygen concentrator?
No, we donāt need a prescription.
Can you fly with a portable concentrator?
Our Products are not FAA-approved, we suggest you useĀ them during the excursion.
How does an oxygen concentrator work?
A portable oxygen concentrator is a device that separates oxygen from the air and allows you to breathe in the oxygen on an as-needed basis. Portable oxygen concentrators can run on both AC and DC power, and they can be charged by both. This battery charge allows it to bring in air, separate the oxygen from the rest of the air, and deliver it back into your lungs at whatever rate is appropriate for you. Some portable oxygen concentrators offer both continuous flows and pulse dose settings.
The home oxygen concentrator is a device that converts air into oxygen, allowing you to breathe easier. It runs on AC power and is only compatible with home or stationary models. The concentrator brings air through the inlet vent into the machine, where it passes through a filter that catches dust and other small foreign particles before going through an oxygen separation system. The oxygen is then released through the tube and cannula in the proper dosage.Are batteries for the portable concentrator rechargeable?
The batteries for your portable oxygen concentrator can be recharged either with the AC power cord or in the car with the DC power cord. They can be recharged inside the concentrator, or if they are external batteries, they can be charged using their cord, or in an external battery charger depending on the model and type of batteries it takes. Battery recharging time varies from concentrator unit to unit, as well as depending on how old your battery is and howĀ much remaining battery life it has left. The average recharge time is 4 to 5 hours.
Are there any portable oxygen concentrators that are continuous flow?
Although many portable oxygen concentrators (POCs) provide only pulse dose oxygen delivery, some units also deliver continuous flow.
NT-05Ā is an oxygen concentratorĀ that provides 3L continuous flow. And the battery can last up to 2 hours.
NT-02Ā 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 usersā breathing patterns, suitable for a broad range of people.
Can an oxygen concentrator be stored in a cold/hotĀ room?
The standard ambient temperature range of our oxygen concentrator is -20ā~60ā. Cold conditions can affect the operating time of portable oxygen concentrator batteries.
Continuous or pulse flow?
A continuous flow oxygen concentrator means the oxygen generator can continuously supply oxygen. But pulse oxygen concentrators usually supply oxygen based on your breathing, because pulse oxygen concentrators usually have breathing sensors.
Products of continuous flow or pulse flow?
OurĀ NT-02 portable oxygen concentratorĀ can supply 1-5 L/min dual mode oxygen flow, adjustable.Ā
OurĀ NT-01 portable oxygen concentratorĀ can supply 1-5 L/min pulse flow, adjustable.Ā
Our NT-05Ā portable oxygen concentratorĀ can supply 3 L/min continuous flow, stable.
Replace filters? how often?
Separately sold, it can be cleaned or replaced every 3-6 months, this is the link

What is the negative ion?
negative ion: Negative oxygen ions can effectively strengthen the ciliary movement of the tracheal mucosal epithelium, affect the activity of respiratory enzymes in the epithelial villi, improve the secretory function of alveoli and the ventilation and ventilation functions of the lung, relieve bronchospasm, increase lung capacity, adjust the respiratory rate, and relieve cough, etc.
What is the Atomization function?
Atomization: The atomization function of the oxygen concentrator uses expertise to help the respiratory system target this one place, so it has few side effects. At the same time, because the atomized very small particles are better absorbed, the damage to the respiratory system is also very small.
