Q1. How to Clean and Maintain the Humidifier Bottle?

A: You can clean the humidifier bottle separately using detergent and warm water. After disassembling the bottle, soak the parts in the solution for 30 minutes, then wipe them dry before reassembling.

Q2. How to Clean and Maintain the Machine's Outer Casing?

A: Once or twice a month, ensure the power is turned off, then use a clean, soft damp cloth with a small amount of detergent to wipe the exterior of the machine. Finally, wipe it dry with a dry towel.

Q3. How to Clean and Maintain the Air Inlet Filter?

A: Remove the air inlet filter from the back of the machine casing. Wash it with detergent, then rinse thoroughly with clean water. After removing excess water, let it air dry naturally. Once completely dry, reinstall it for continued use.

Do not reinstall the filter if it is still damp. Cleaning the air inlet filter is an essential part of regular oxygen concentrator maintenance, and it is recommended to clean it at least twice a month.

Q4. How Much Should I Set the Oxygen Flow Rate?

A: Since oxygen therapy should be administered under a doctor's recommendation, please consult your physician for the appropriate flow rate.

(Note: The OC503/OC505 oxygen concentrator has a maximum flow rate of 5 liters per minute.)

Q5. What Type of Water Should I Use in the Humidifier Bottle?

A: Please use drinking water or distilled water with a temperature below 40°C (104°F).

Q6. What Should I Do If There Are Water Droplets in the Nasal Cannula?

A: There are two possible causes for this issue:

Overfilled humidifier bottle – If the water level exceeds the recommended maximum line, water may enter the nasal cannula.
Condensation from prolonged use – Water vapor can condense inside the nasal cannula over time.

Recommended solutions: Reduce the water level in the humidifier bottle, ensuring it does not exceed the maximum water level line. Additionally, replace the nasal cannula and let the one with water droplets air dry before reuse.
