Comprehensive Guide on Maintaining and Caring Oxygen Concentrators

Oxygen concentrators are lifelines for countless individuals around the world who depend on them to manage respiratory conditions and maintain their overall health and well-being. 

These remarkable devices have revolutionised the way we deliver oxygen therapy, offering a consistent and cost-effective source of oxygen to those in need. The importance of oxygen concentrators cannot be overstated, as they empower individuals with conditions like chronic obstructive pulmonary disease (COPD), asthma, and other respiratory ailments to lead more fulfilling lives.

However, the efficacy and safety of these life-saving machines hinge significantly on their proper maintenance and care. Regular maintenance is essential to ensure that oxygen concentrators continue to provide the prescribed oxygen levels accurately and reliably.

In this blog, we will delve deeper into the significance of proper maintenance practices, offering valuable insights into how to keep these devices in optimal working condition, ultimately ensuring the health and well-being of individuals who depend on them.

Why does maintenance matter?

Reduced performance: Without proper maintenance, oxygen concentrators may not deliver the prescribed oxygen levels accurately and reliably, compromising their effectiveness in managing respiratory conditions.

Compromised safety: Failure to maintain oxygen concentrators can lead to safety hazards, such as malfunctioning parts or electrical issues, which could potentially harm the user.

Health risks: If oxygen concentrators are not properly maintained, they may become contaminated with dust, dirt, or other allergens, which can be detrimental to the user’s respiratory health.

Daily Care Routine

Check power sources: Ensure that your oxygen concentrator is properly connected to a reliable power source. Check the power cord for any damage or frayed wires.

Inspect tubing: Regularly inspect the tubing for any kinks, leaks, or signs of wear and tear. Replace any damaged tubing promptly to maintain a consistent oxygen flow.

Clean filters: Clean or replace filters as recommended by the manufacturer. Dust and debris can accumulate on the filters, hindering the device’s performance and potentially compromising your respiratory health.

Weekly Maintenance Tasks

Check for loose connections: Inspect all connections and ensure that they are secure. Loose connections can result in decreased oxygen flow and compromised effectiveness.

Monitor oxygen purity levels: Use an oxygen purity meter to check the oxygen purity levels regularly. Ensure that the concentrator is delivering the prescribed level of oxygen.

Clean the exterior: Wipe down the exterior of the oxygen concentrator with a clean, damp cloth to remove any dust or debris. Keeping the device clean not only improves its aesthetics but also helps prevent the accumulation of contaminants.

Monthly Maintenance

Check the flow rate of your concentrator to ensure it is delivering the prescribed oxygen levels accurately. Consult the user manual or contact the manufacturer for instructions on how to assess the flow rate.

Clean the humidifier, if your concentrator has one, to prevent the growth of bacteria or mould. Follow the manufacturer’s guidelines for cleaning and disinfection.

Examine the tubing for any kinks, leaks, or signs of wear and tear. Replace any damaged tubing promptly to maintain a consistent oxygen flow.

Test the battery life, if applicable, to ensure it is holding a charge effectively. If you notice a significant decrease in battery life, it may be time to replace the battery.

Cleaning and disinfection


  • Turn off and unplug the concentrator from the power source.
  • Gather your supplies: Mild detergent (like Dawn or another gentle dish soap), soft cloths, distilled water, and a 3% hydrogen peroxide solution for disinfection.

Exterior Surface Cleaning:

  • Dampen a soft cloth with a mixture of mild detergent and water.
  • Wipe down the exterior surfaces of the concentrator, ensuring all dust and contaminants are removed.
  • Use another soft cloth dampened with distilled water to wipe off any detergent residue.
  • Allow surfaces to air dry.

Filter Cleaning:

  • Locate and carefully remove the filter from the concentrator. Most concentrators have a removable external filter.
  • Gently rinse the filter under cool water until the water runs clear.
  • Allow the filter to air dry completely before reinserting it into the concentrator. Ensure the filter is not damp, as moisture can damage the equipment.

Nasal Cannula and Tubing Cleaning (if applicable):

  • Disconnect the nasal cannula and tubing from the concentrator.
  • Soak them in a mixture of mild detergent and water for a few minutes.
  • Rinse thoroughly with distilled water to remove all detergent residues.
  • Allow them to air dry on a clean surface. Make sure they are completely dry before reconnection.


  • After cleaning, dampen a cloth with a 3% hydrogen peroxide solution.
  • Wipe down the exterior surfaces of the concentrator, the nasal cannula, and tubing.
  • Allow to air dry. The hydrogen peroxide will disinfect the surfaces and then naturally evaporate.

Reassemble and Store:

  • Once all parts are completely dry, reassemble the concentrator. 
  • Store in a clean, dry area away from direct sunlight.

Troubleshooting Common Issues

Low oxygen flow: If you notice a decrease in oxygen flow from your concentrator, first check if the tubing is properly connected and not twisted or kinked. Ensure that the oxygen outlet is not obstructed by any objects or debris. If the issue persists, contact the manufacturer or your healthcare provider for further assistance.

Strange noises: Unusual noises coming from your oxygen concentrator could indicate a problem. Check if the device is properly placed on a stable surface and is not vibrating excessively. Make sure there are no loose parts or debris inside the concentrator. If the noises persist or seem unusual, contact the manufacturer or your healthcare provider.

Error codes: If your concentrator displays error codes, consult the user manual for troubleshooting instructions. Each error code indicates a specific issue that may require professional attention. Avoid attempting any repairs or modifications on your own.

Alarm alerts: If the concentrator’s alarm goes off, first check if there is a power outage or if the device is properly connected to a power source. Verify that the oxygen flow settings are appropriate for your needs. If the alarm continues to sound or if it indicates a critical issue, contact the manufacturer or your healthcare provider immediately.

Battery care

Regular charging: Charge your oxygen concentrator battery as recommended by the manufacturer. It is important to keep the battery charged to avoid any interruptions in oxygen therapy.

Avoid overcharging: Overcharging the battery can lead to decreased battery life and performance. Follow the manufacturer’s guidelines on charging time to prevent overcharging.

Store properly: When not using your oxygen concentrator with the battery, store the battery in a cool and dry place. Avoid exposing the battery to extreme temperatures or moisture.

Check battery life: Regularly monitor the battery life to ensure it is holding a charge effectively. If you notice a significant decrease in battery life, it may be time to replace the battery.

Replace when necessary: Over time, batteries can degrade and lose their capacity to hold a charge. If your oxygen concentrator battery no longer provides sufficient power, contact the manufacturer or your healthcare provider to purchase a replacement.

So, oxygen concentrators play a pivotal role for individuals with respiratory issues, ensuring they receive a consistent and dependable source of oxygen.

However understanding their care is just as critical, from recognizing the importance of the device’s settings, flow rates, and safety measures to realizing the necessity of regular cleaning, changing filters, and periodic servicing.

By adhering to the guidelines and recommendations discussed throughout, you can guarantee the optimal performance and durability of your oxygen concentrator. And for anyone who relies on this essential medical equipment, that’s a promise of better health and peace of mind.
