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 The 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.

Negative ion function:Purifies the air by releasing negative ions, providing a fresher breathing environment. Negative ions can absorb dust, bacteria, viruses, and other harmful substances in the air, and purify the odor and smoke in the air, providing a cleaner air quality.

Atomization function:convert liquid medicine into tiny mist particles, inhale into the respiratory tract and lungs through breathing, and play a role in treating and alleviating respiratory diseases. Nebulization therapy is often used in the treatment of asthma, chronic obstructive pulmonary disease, bronchitis, and other diseases. Through aerosol inhalation, the drug can act on the lesion more directly, accelerating the speed of absorption and onset of effect.Effect:

1. Negative ions can provide a fresher breathing environment, purify harmful substances in the air, and improve indoor air quality.
2. Negative ions help to improve immunity, improve respiratory diseases, relieve fatigue and anxiety, etc.
3. The atomization function can directly deliver the medicine to the respiratory tract and lungs, improve the therapeutic effect and speed up the remission of the disease.
4. Nebulization treatment is convenient and simple, suitable for people of all ages, especially for young patients or patients with limited mobility.

Yes, our NT-01 & NT-02NT-03&NT-05& are CE-certified.

Yes, with or without water, both will be OK, if you add water to use, the oxygen you breathe will be more humid.

VARON portable oxygen concentrator can use AC power supply 100-240V and DC power supply 12-16.8V operation. So it can be used in worldwide and vehicle charge.

Generally speaking, the sound output of most oxygen concentrators ranges from about 40 decibels (DBA) to about 60 decibels. This is the volume of quiet conversations or quieter whispers. The VARON VP-01 has been tested and the sound is below 58 decibels. VARON VL-02 has been tested below 45 decibels.

Regularly maintain the appearance of the portable oxygen concentrator and carefully wipe around the vents. To remove dirt, rub the surface lightly.Clean the nasal cannula at least once a week. If it is used daily, it is best to change the nasal cannula every two months. If you don't use it frequently, replace it every three to six months.The filter of the portable oxygen generator can remove dust, dirt, and pollen from the air. Cleaning the filter once a month can extend the service life of the unit.

So sorry to tell you that We have not cooperated with any medical insurance company.Our product is a healthcare machine, If you have specific requirements for oxygen concentration or oxygen flow rate, please choose our products according to your actual situation.

Two types of oxygen concentrators

If your oxygen generator filter can be removed and cleaned, you need to change it every 3 months.

Our Products are not FAA-approved, we suggest you use them during the excursion.

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 own cord, or in an external battery charger depending on the model and type of batteries it takes.

Our portable oxygen concentrators have batteries, and the NT-01 is a built-in battery, so it cannot be replaced. NT-02/NT-03/NT-05 are external batteries, you can buy spare batteries.

Pulse flow:a way of delivering oxygen based on changes in breathing rate, it gives oxygen when you breathe in and gives out oxygen when you don't breathe in.

Continuous flow:Provides oxygen at a constant rate, regardless of your breathing rate, and delivers oxygen at a fixed flow rate.
