What is an Oxygen Concentrator?

An Oxygen Concentrator is a device used in medical settings that extracts oxygen from the air and delivers it to individuals in need of additional oxygen due to various medical conditions.

The device has the ability to concentrate the oxygen to a purity level of 90% to 95%. Unlike oxygen tanks, the concentrator does not require refilling or topping up and instead runs on a power supply to operate.


Is the Oxygen Concentrator easy to use?

Yes, there is a switch located at the front of the concentrator that can be used to turn it on or off easily.

What is the recommended usage time and setting for the Oxygen Concentrator?

The oxygen concentrator is designed to run 24 hours, as long as you have a direct power supply, the oxygen concentrator will keep giving oxygen. It is recommended to consult a medical expert regarding the appropriate oxygen flow rates and duration of usage.

How to connect the humidifier bottle & tubing and why do you need one?

1. Fasten the humidifier bottle to the machine using the provided velcro strap.
2. Connect the humidifier tubing to link the humidifier bottle and the oxygen concentrator.
3. Place the humidifier tubing onto the oxygen outlet by sliding it over.
4. Attach a nasal cannula to the humidifier.

It is not necessary to use a humidifier with the oxygen concentrator. Use a humidifier when you feel that the air is too dry for your comfort.


Can I use tap water for the humidifier bottle?

No, it is not recommended to use tap water in the humidifier bottle for an oxygen concentrator. Tap water contains minerals and other impurities that can build up in the concentrator and cause damage to the machine over time.

Washing & Care Instructions

1. Always use distilled / sterile water and change it daily
2. Once a week, wash the humidifier in mild soapy water and rinse in clear water
3. Then soak in vinegar solution (1 part vinegar 3 parts water) for 30 mins, then rinse again in clear water


What is the maintenance required?

There is a dust filter at the back of the oxygen concentrator that needs to be washed weekly. We also recommend that the oxygen concentrator is serviced at least once a year.

External Filter
• Wash the removable filters every 3 days or a week so that the dust do not accumulate too much, hence it may be easier to clean
• Try with warm water and soap and see if it comes off easier

Inlet Filter
• Once a year or when machine has been operating for 5000 hours, whichever comes first


Can I use extension cables?

To ensure optimal performance of the Oxygen Concentrator, we advise customers against using extension cables. Instead, we recommend connecting the machine directly to a power source.

Using an extension cable can lead to power sharing with other appliances, potentially causing the Oxygen Concentrator to run on insufficient power, leading to improper function.
