How to Clean and Maintain an Oxygen Concentrator at Home (Malaysia 2026)
A simple weekly routine to keep your oxygen concentrator clean, safe, and delivering 90%+ purity for years.
Table of Contents
Introduction
A well-maintained oxygen concentrator lasts longer, runs quieter, and delivers safer oxygen.
Most concentrator faults in Malaysian homes are caused by neglected filters and dirty humidifier bottles. A 10-minute weekly routine can prevent over 90% of breakdowns and keep oxygen purity above 90%.
Daily cleaning routine
Wipe and inspect
Wipe the cabinet with a damp cloth (no harsh chemicals). Check that the air intake at the back is not blocked by furniture or dust.
Check the cannula
Look for kinks, splits, or yellowing. Replace immediately if the tube is discoloured.
Weekly maintenance
Clean the humidifier bottle
Empty the bottle. Wash with warm water and mild dish soap. Rinse thoroughly. Refill only with distilled water, not tap water — minerals will build up and damage the bottle.
Wash the cannula
If using the same cannula long-term, rinse with warm soapy water and air-dry once a week. Replace the cannula every 2–4 weeks regardless.
Check the inlet filter
Most units have a sponge filter on the back. Slide it out, rinse with cool water, squeeze dry, replace.
Monthly tasks
- Inspect tubing for cracks
- Run the unit for 10 minutes with no cannula attached to clear internal dust
- Check the power cable for fraying
- Confirm oxygen purity if you have a portable oxygen analyser (most rentals include one on request)
Oxihome's rental units come with all filter swaps included — message us on WhatsApp when you need replacements.
Understanding the filters
Three filters in most concentrators
- Inlet sponge filter — washable, lasts 1–3 months
- Internal HEPA filter — replaced every 6–12 months by technician
- Outlet bacterial filter — replaced every 12 months
Why filters matter
Filters protect the molecular sieve beds inside the machine. If filters are dirty, the sieves work harder, get clogged faster, and oxygen purity drops below 85% — which negates the therapy.
Common issues and quick fixes
Machine beeping continuously
Usually means low oxygen purity or overheating. Turn off, let it rest 10 minutes, clean the inlet filter, restart.
Low or no flow
Check for kinks in the tubing. Verify the humidifier bottle is not over-tightened.
Unit getting hot
Move it away from walls. Concentrators need 15 cm of clearance for cooling.
Strange smell
Could be dust burning off — normal on first use, abnormal otherwise. Power off and call your supplier.

FAQ
Can I use tap water in the humidifier?
No. Always use distilled water — tap water leaves mineral deposits.
How often should I replace the cannula?
Every 2–4 weeks, or immediately if torn or discoloured.
What if the alarm keeps going off?
Stop using the unit and call your supplier. Do not ignore an alarm.
Do you provide filter replacements?
Yes, free for all rental customers.
Can I service the concentrator myself?
Only external cleaning. Internal service should be done by a trained technician.
