Using an oxygen concentrator at home can significantly improve the quality of life for people with respiratory conditions such as COPD, asthma, or post-COVID recovery. However, proper usage and safety are essential to ensure effective therapy and prevent risks like fire hazards or incorrect oxygen delivery.
In this step-by-step guide by Greenwell Healthcare, you will learn how to use an oxygen concentrator safely and efficiently at home.
What is an Oxygen Concentrator?
An oxygen concentrator is a medical device that draws in room air, removes nitrogen, and delivers oxygen-rich air with high purity levels. Unlike oxygen cylinders, it provides a continuous oxygen supply as long as it is connected to a power source, making it ideal for home use.
Step-by-Step Guide to Using an Oxygen Concentrator
Step 1: Choose the Right Location
Place the concentrator in a well-ventilated area with enough space around it for proper airflow.
- Keep it at least 1–2 feet away from walls and furniture
- Avoid placing it near curtains or enclosed spaces
- Keep away from heat sources
Proper placement helps the machine function efficiently and prevents overheating.
Step 2: Plug into a Safe Power Source
Always plug the device directly into a wall socket.
- Avoid extension cords
- Do not overload the socket
- Ensure stable electricity supply
This reduces the risk of electrical hazards and ensures uninterrupted performance.
Step 3: Attach the Humidifier Bottle (If Prescribed)
If your doctor recommends a humidifier:
- Fill it with distilled or sterile water
- Do not overfill the bottle
- Secure it properly to avoid leakage
Using the correct water type helps prevent infections.
Step 4: Connect the Nasal Cannula or Mask
Attach the oxygen tubing to the outlet and place the cannula in your nostrils or wear the mask comfortably.
- Ensure tubing is not bent or blocked
- Adjust for a secure and comfortable fit
Step 5: Turn On the Device
Switch on the concentrator and allow it to stabilize.
- Wait for a minute before use
- Check indicator lights for normal functioning
Step 6: Set the Prescribed Flow Rate
Adjust the oxygen flow according to your doctor’s prescription.
Do not change the flow rate without medical advice, as incorrect levels can be harmful.
Step 7: Check Oxygen Output
Ensure the device is delivering oxygen properly.
- Feel airflow from the cannula
- Monitor indicators or alarms
- Listen for unusual sounds
Important Safety Tips
Fire Safety
Oxygen supports combustion, so extra care is required.
- Do not smoke near the concentrator
- Keep away from flames, gas stoves, and heaters
- Maintain a safe distance from heat sources
Avoid Flammable Products
Certain products can become hazardous in oxygen-rich environments.
- Avoid aerosol sprays like room fresheners or hair sprays
- Do not use oil-based lotions or petroleum jelly

- Avoid using damaged wires or plugs
- Do not use electrical appliances like hair dryers while on oxygen
Proper Placement
- Keep the concentrator upright at all times
- Do not block air vents
- Ensure free airflow around the machine
Safety Around Family

Cleaning and Maintenance Tips
Maintaining hygiene is essential for safe oxygen therapy.
- Clean filters weekly using mild soap and water
- Let filters dry completely before reuse
- Clean the humidifier bottle daily
- Wipe the outer surface regularly
Regular maintenance improves performance and extends the device’s lifespan.
Common Mistakes to Avoid
- Changing oxygen levels without consulting a doctor
