Your oxygen concentrator is one of the most important medical devices in your home. Whether you rely on it around the clock or only during sleep, keeping it properly maintained is essential — not just for the device’s longevity, but for your health and safety. Neglecting regular care can lead to reduced oxygen purity, unexpected breakdowns, and costly repairs.
At Oxyfix, we service hundreds of oxygen concentrators across South Africa every year. Here are the seven maintenance habits our technicians recommend most.
1. Clean the Air Filter Weekly
The air intake filter is your concentrator’s first line of defence against dust and airborne particles. A clogged filter forces the compressor to work harder, reducing efficiency and potentially shortening the motor’s lifespan.
How to do it: Remove the filter panel (usually on the side or back), gently wash the foam filter in warm soapy water, rinse thoroughly, allow it to air-dry completely, and reinsert. Never run the machine with a wet filter.
2. Wipe Down the Exterior Regularly
Dust and household grime can accumulate on vents and surfaces, restricting airflow. Use a slightly damp cloth to wipe down the outside of the unit weekly. Avoid harsh chemical cleaners or spraying liquids directly onto the device.
3. Keep the Area Around Your Device Clear
Oxygen concentrators need good airflow to function efficiently. Ensure at least 30 centimetres of clear space on all sides of the unit. Avoid placing it in enclosed cabinets, near curtains, or in rooms with poor ventilation.
4. Check the Tubing and Cannula Daily
Inspect your oxygen tubing and nasal cannula every day for cracks, kinks, or blockages. Replace the cannula every two to four weeks, or sooner if you notice any damage. Kinked tubing reduces oxygen flow even when the machine is performing normally.
5. Monitor the Oxygen Purity Indicator
Most modern concentrators have a purity alarm or indicator light. If yours alerts you to low oxygen output, do not ignore it. Reduced purity (below 87%) can mean the molecular sieve beds are exhausted and require professional replacement — something only a qualified technician should perform.
6. Keep a Service Log
Note down the machine’s running hours, any unusual sounds, and the dates of your at-home cleaning. This information is invaluable when booking a professional service — it helps technicians diagnose issues faster and keeps your warranty valid with most manufacturers.
7. Book a Professional Service Every 6–12 Months
Even with diligent home care, your concentrator needs professional attention at least once a year. A qualified technician will replace sieve beds, check compressor pressure, test oxygen output, and inspect internal components that are inaccessible to end users.
At Oxyfix, our standard service includes a full 14-point inspection, genuine replacement parts, and a written report. Most services are completed within 1–3 working days, and loan units are available so your therapy is never interrupted.
Conclusion
Maintaining your oxygen concentrator doesn’t require technical skills — just consistent habits and the right professional support. Follow these seven steps and your device will deliver reliable, safe oxygen therapy for years to come.
