Cleaning and Maintaining Your Oxygen Concentrator

Updated October 2026.

Regular cleaning keeps your oxygen concentrator delivering oxygen effectively and can help it last longer. A few simple habits go a long way. Always follow your manufacturer’s user manual — it’s the final word for your specific model.

Clean the outside

• Turn the unit off and unplug it first
• Wipe the case with a soft, damp cloth and mild soap; avoid harsh chemicals and never spray liquid directly on the unit
• Make sure air intakes and vents are clear of dust and lint

Check the filters

Most concentrators have one or more particle filters that keep dust out. Many can be rinsed and air-dried; others need replacing. Check them regularly — more often in dusty or humid conditions — and follow your manual’s schedule.

Replace cannulas and tubing

Nasal cannulas and tubing wear out and can collect bacteria. Many people replace cannulas every few weeks and tubing every month or two — or sooner if they get stiff, discolored or damaged. Ask your doctor or check your manual for recommendations.

Care for your batteries

• Never leave your concentrator or batteries in a hot car — Florida heat can damage batteries quickly
• Store spare batteries in a cool, dry place
• Use your concentrator on AC or DC power when you can to save battery cycles

Home concentrators with humidifiers

If you use a humidifier bottle, clean it regularly and refill it with distilled water as your manual directs.
