A well-maintained oxygen concentrator delivers consistent, medically appropriate oxygen purity and lasts significantly longer than a neglected one. The maintenance tasks required are straightforward and do not require technical skills. What they do require is regularity.
The most important daily task is checking the intake filter. Most home concentrators have a foam or mesh filter on the outside of the unit that prevents dust from entering the compressor. In dusty indoor environments — which describes most Indian homes in summer months — this filter should be visually checked daily and cleaned every two to three days. To clean it, remove the filter, wash it in warm water without soap, squeeze out excess water gently, and allow it to dry completely before replacing it. Never run the concentrator with a wet or missing filter.
Weekly, wipe down the exterior of the unit with a dry or lightly damp cloth. Do not use alcohol-based cleaners or sprays near the air intake. Check the humidifier bottle if your device uses one — empty it, rinse it with clean water, and refill it to the indicated level with distilled water. Tap water introduces mineral deposits that can breed bacteria over time.
Monthly, inspect the power cord and all tubing for cracks, kinks, or discolouration. Replace any nasal cannula or mask that shows signs of cracking, stiffness, or odour — these components are consumables and should be replaced every two to four weeks with regular use. Check the cannula prongs for blockages.
Every six months, the internal bacterial filter on most concentrators requires replacement. This is a serviceable component supplied by TCH Medical. Do not skip this service interval; a clogged internal filter reduces output purity without triggering an alarm on some older models.
Placement matters: keep the concentrator at least 30 cm away from walls on all sides to allow adequate airflow. Avoid placing it near curtains, bedding, or other soft furnishings that restrict ventilation. Never cover the unit or place objects on top of it.
If the device emits an alarm, displays a fault code, or you notice any change in how you feel during therapy, stop use and contact TCH Medical's support line before resuming. Do not attempt to open the casing or service internal components yourself.
