An oxygen concentrator is a high-value, life-sustaining piece of medical equipment. Proper, consistent maintenance is paramount to ensuring the machine consistently delivers oxygen at the prescribed 93% purity level, prolonging its lifespan far beyond the expected 10,000 hours of operation. Ignoring simple maintenance can strain the internal compressor and prematurely degrade the molecular sieve beds.

The Essential Maintenance Schedule

Daily Checks: Always inspect the humidifier bottle (if used) to ensure it is filled only with distilled water and securely connected; never use tap water, as mineral deposits will damage the system. Check the nasal cannula and oxygen tubing for kinks, twists, or blockages, which severely restrict oxygen flow and trigger low-purity alarms.

Weekly Cleaning (User Level): The exterior gross particle filter (usually a sponge or mesh) must be removed, washed gently with warm, mild soapy water, rinsed thoroughly, and allowed to air-dry completely before reinsertion. Running the machine with a damp filter can cause moisture damage. Use a soft, damp cloth to wipe down the machine’s exterior and control panel, avoiding electrical ports.

Professional Servicing (Technician Level): The most critical internal component is the molecular sieve bed, which separates nitrogen from ambient air. Over time, humidity and wear reduce the sieve’s efficiency, lowering the oxygen purity. We recommend scheduling a professional inspection annually with certified suppliers like Techno Health. Technicians will check the internal bacterial filter, calibrate the sensor, and assess the sieve bed status, addressing small mechanical issues before they become catastrophic failures. Additionally, always protect your investment from Bangladesh’s fluctuating power supply using a reliable surge protector or voltage stabilizer.
