Oxygen Concentrator Maintenance Guide
Stationary & Portable Devices · Patient Reference · July 2026Stationary Oxygen Concentrators
Home stationary concentrators (DeVilbiss 525DS / 1025DS, Respironics EverFlo, Invacare Platinum, CAIRE AirSep) run continuously and depend on clean airflow. Keeping filters clear is the single most impactful maintenance task.
Clean the Intake Filter
Weekly or as directed. The large foam cabinet filter on the back or side traps household dust. Remove it, rinse with warm water, let it air dry completely, then reinstall. Never run the concentrator with a wet or missing filter.
Ensure Proper Clearance
Always. Keep at least 12 inches of clear space on all sides. Do not place it against a wall, inside a closet, or near curtains or bedding. Restricted airflow causes the compressor to overheat and sieve beds to wear prematurely.
Clean the Humidifier Bottle
Daily if used. Empty the bottle, rinse with mild soap and warm water, and refill with distilled water only. Replace the bottle every 6 months or if you see discoloration, cracks, or mineral buildup that cannot be cleaned.
Inspect Tubing & Cannula
Weekly. Check tubing for kinks, cracks, or discoloration. Replace nasal cannulas every 2–4 weeks or sooner if stiff or irritating. Cracked tubing allows oxygen to leak before it reaches you, reducing your effective flow rate.
Test Alarms Monthly
Monthly. Follow your manual’s alarm test procedure to confirm the low-oxygen alarm triggers. A non-functional alarm is a safety hazard. If it does not sound, contact your HME provider or a qualified technician immediately.
Follow Oxygen Safety Rules
Always. Keep the unit at least 5 feet from open flames, gas stoves, candles, and smoking areas. Post “No Smoking — Oxygen in Use” signs. Never use aerosols, oils, or petroleum-based products near the device or your cannula.

Portable Oxygen Concentrators
Portable concentrators (Philips SimplyGo, Invacare Platinum Mobile, Respironics SimplyGo Mini) travel with you and face added stressors — heat, vibration, dust, and variable charging. Battery care and filter cleanliness are especially critical.
Clean the Particle Filter
Weekly or more often when traveling. Locate the small intake filter (check your manual — typically on the bottom or side). Tap gently to dislodge dust, or rinse if washable. Let it dry completely before reinstalling. A clogged filter reduces oxygen output.
Care for Your Battery
Ongoing. Avoid storing with a completely depleted battery for more than a week — this permanently reduces capacity. Store at ~40–60% charge. Charge at room temperature; heat significantly shortens lithium battery life.
Avoid Extreme Temperatures
Always. Never leave the unit in a parked car during summer. Heat above 104°F (40°C) can damage sieve beds, the battery, and electronics. After extreme cold, allow the unit to reach room temperature before use.
Air Travel Preparation
Before each flight. Confirm FAA approval. Notify the airline 48+ hours in advance. Bring enough battery for 150% of total travel time including layovers. Carry your prescription and doctor’s letter. Never check the device as baggage.
Inspect Tubing & Cannula
Before each use. Portable units move with you, making tubing more prone to kinking. Replace cannulas every 2 weeks for active users. Any leak between the unit and your nose reduces your actual oxygen dose.
Keep Vents Unobstructed
During all operation. Do not carry the unit in a bag that covers intake and exhaust vents. Use only carry cases designed for your specific model. Covering vents while running causes rapid overheating and protective shutdown.

When to Call a Professional
Routine cleaning can be done at home, but the following symptoms require a qualified biomedical technician. Contact your HME provider or call (877) 684-9778 if you notice:
- The low-oxygen or alarm indicator is on and does not clear after checking tubing and filters
- Your SpO₂ (blood oxygen) readings are lower than your prescribed target while using the device
- The unit produces a new grinding, rattling, or high-pitched sound
- The device runs unusually hot or shuts itself off
- Oxygen output smells unusual or has visible contamination
- The battery on a portable unit no longer holds a charge for its rated duration
- The device has been dropped, submerged, or physically damaged
