When using an oxygen generator, do not use the oxygen generator near an open flame or while smoking.
Pay attention to the oxygen level and check the device regularly for alarms to ensure you are getting enough oxygen. Too low an oxygen level will affect the breathing effect of the oxygen and the service life of the oxygen concentrator.
If you need to use an oxygen concentrator due to chronic health problems, pay attention to monitoring changes in your blood oxygen levels at all times.
What is the difference between continuous flow and pulsatile flow?
Pulse flow: During use, it can automatically detect your breathing pressure, release the necessary oxygen in time when you inhale, and stop the operation when you exhale. Continuous flow: Continuous flow releases oxygen regardless of whether you inhale or exhale. At present, pulse flow mode is mainly used in portable devices, so the device has a longer operating time.

In general, the sound power of most oxygen concentrators ranges from about 30 decibels (DBA) to about 60 decibels. This is equivalent to the volume of a quiet conversation or a quieter whisper. The VARON VP-01 has been tested and the sound is less than 58 decibels. The VARON VL-02 has been tested at less than 45 decibels.

When the oxygen concentrator device is not working properly, the device alarm will light up. At the same time, an alarm code will also appear on the display:

F0001: Low battery alarm

F0002: No breathing detected

F0011: High temperature alarm

F0012: Oxygen sensor abnormal alarm

A portable oxygen concentrator is a device that separates oxygen from the air and allows you to breathe oxygen as needed. Portable oxygen concentrators operate on both AC and DC power, and can be charged on either. Battery charging allows the device to bring in air, separate the oxygen from the rest of the air, and deliver it back to your lungs at a rate that is convenient for you. Some portable oxygen concentrators have both continuous flow and pulse dose settings.

A home oxygen concentrator is a device that converts air into oxygen, making it easier for you to breathe. It is powered by mains electricity and is only compatible with home or fixed installation models. The concentrator draws air into the device through an inlet, where it passes through a filter that traps dust and other small foreign particles before passing through an oxygen separation system. Oxygen is then delivered through a hose and cannula at the correct dosage.

The batteries in a portable oxygen concentrator can be charged either with an AC power cord or with a DC power cord in a car. They can be charged inside the concentrator, or in the case of external batteries, they can be charged with their own cord or with an external battery charger, depending on the model and battery type. The charging time for batteries varies between concentrator units, as well as how old the battery is and how much battery power is left. The average charging time is 4-5 hours.

Atomization: The atomization function of the oxygen concentrator uses expertise to help the respiratory system focus on this one spot, 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.

The VARON portable oxygen concentrator can operate on 100-240V AC power and 12-16.8V DC power. So it can be used worldwide and for vehicle charging.

Our home oxygen machines are suitable for you, they can operate 24/7, even while you sleep.

Our product is a healthcare device, so it does not need a prescription. If you have special requirements for oxygen concentration or oxygen flow rate, please choose our product according to your actual situation.

A portable oxygen concentrator is a type of oxygen therapy device that is convenient to carry around. It provides treatment for those who need higher oxygen concentrations than ambient air levels when traveling or outdoors. It is small and lightweight, and has a battery that can be started at any time.

Compared to portable oxygen generators, home oxygen concentrators are larger and heavier. They cannot be easily transported and used while traveling. They can produce high flow rates and are recommended for patients who require large amounts of oxygen.

Oxygen concentrators can be divided into two uses according to the oxygen flow rate: healthcare and disease treatment.

The 1-3 liter oxygen concentrator is suitable for healthcare: pregnant women, elderly healthcare, students, white-collar workers and other mental health workers can use it, and it is suitable for daily oxygen therapy.
Oxygen concentrators with a capacity of more than 3 liters are suitable for the treatment of diseases: It can be used for patients with chronic diseases (hypertension, hyperglycemia, hyperlipidemia, coronary artery disease, obesity, etc.), patients with respiratory diseases, cardiovascular diseases and cerebrovascular diseases, and patients with heart and lung function diseases. It is suitable for home oxygen therapy.

Regularly maintain the appearance of your portable oxygen concentrator and wipe carefully around the vents. Remove dirt by gently rubbing the surface.
Clean your nasal cannula at least once a week. If you use it daily, you should replace it every two months. If you don't use it often, replace it every three to six months.
The filter of a portable oxygen generator can remove dust, dirt, and pollen from the air. Cleaning the filter once a month can extend the life of the device.
