FAQs

• When using an oxygen generator, do not use the oxygen generator near an open flame or while smoking.
• Pay attention to the oxygen concentration, and check your equipment regularly to see if there are any alarms to make sure you get enough oxygen. Too low oxygen concentration will affect the oxygen inhalation effect 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 the changes in your blood oxygen level at all times

Pulse flow: During use, it can automatically detect your breathing pressure, release the required oxygen in time when you breathe in, and stop working when you breathe out. Continuous flow releases oxygen regardless of whether it is inhaling or exhaling. At present, the pulse flow mode is mainly used in portable device, so that the use time of the machine is longer.

Generally speaking, the sound output of most oxygen concentrators ranges from about 30 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.

When the oxygen concentrator equipment is not working properly, the alarm of the device will light up. The alarm code will also be displayed at the same time:

F0001: Low battery alarm

F0002: No breathing detected

F0011: High temperature alarm

F0012: Abnormal alarm of oxygen sensor

No, we don’t need a prescription.

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

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.

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. Battery recharging time varies from concentrator unit to unit, as well as depending on how old your battery is and how much remaining battery life it has left. The average recharge time is 4 to 5 hours.

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.

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

Our home oxygen machines are suitable for you, they can work for 24h/7d, even when sleeping.

Our light series devices have over-heat protection, it will stop every 4 hours 

It can be added water, you can add the water according to your need.

Our portable oxygen concentrator VP-2 is equipped with replaceable batteries which you can replace anytime in need to extend the using time.

Our home series product VH-3 is a water-free machine. You do not need to add water when operating.

Varon has three series of products: Portable series, Home series, and Light series. 

You can read our product guide to get more details about those different series of products. 

 

Our product is a health care machine, so it does not need a prescription. If you have specific requirements for oxygen concentration or oxygen flow rate, please choose our products according to your actual situation.

The portable oxygen concentrator is a kind of oxygen therapy equipment that is convenient to carry around. It provides treatment for those who need higher oxygen concentrations than ambient air levels while traveling or going out. It is small in size, light in weight, and contains a battery that can be powered at any time.

Compared with portable oxygen generators, home oxygen concentrators are larger and heavier. It cannot be easily carried and used when traveling. They can provide high flow rates and are recommended for patients who require a large amount of oxygen supply.

The oxygen concentrator can be divided into two purposes according to the oxygen flow rate: health care and disease treatment.

• 1-3L oxygen concentrator is suitable for health care: ePregnant women, elderly health care, students, white-collar workers and other mental workers can use it, and it is suitable for daily oxygen therapy.
• Oxygen concentrator larger than 3L are suitable for disease treatment: It can be used in patients with chronic diseases (hypertension, hyperglycemia, hyperlipidemia, coronary heart disease, obesity, etc.), patients with respiratory diseases, cardiovascular and cerebrovascular diseases, and patients with cardiopulmonary functional diseases. It is suitable for oxygen therapy at home.

• 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 in the air. Cleaning the filter once a month can extend the service life of the unit.
