For residents in Sydney and across Australia managing chronic respiratory conditions, the EverFlo oxygen concentrator by Philips Respironics has become the gold standard for reliable, home-based care. Choosing the right medical equipment is a significant decision that impacts your daily comfort and long-term health outcomes.
This comprehensive guide explores why the EverFlo remains a top choice for Australian patients, detailing its technical specifications, maintenance requirements, and practical tips for maximizing the lifespan of your device. Whether you are looking to purchase your first unit or seeking advice on maintaining an existing one, this resource provides the professional insights you need.
What is the EverFlo Oxygen Concentrator?
The EverFlo oxygen concentrator is a stationary medical device designed to provide a continuous flow of supplemental oxygen to patients with respiratory disorders such as COPD, emphysema, or chronic bronchitis. Unlike oxygen tanks that require regular refills or deliveries, the EverFlo concentrates the air around you, providing an endless supply of medical-grade oxygen as long as it is connected to a power source.
In the Australian market, the EverFlo (often referred to simply as the “Philips EverFlo”) is highly regarded for its “non-medical” aesthetic. Its sleek, compact design allows it to blend into home environments more naturally than older, bulkier models.

How the EverFlo Oxygen Concentrator Works
The science behind the EverFlo involves a process called Pressure Swing Adsorption (PSA). The device draws in ambient room air—which typically contains about 21% oxygen and 78% nitrogen—and passes it through a series of filters and “sieve beds.”
- Air Intake: The compressor pulls in room air.
- Nitrogen Removal: The air is pressurized and passed through molecular sieves that trap nitrogen molecules.
- Oxygen Concentration: The remaining concentrated oxygen (up to 96% purity) is stored in a small reservoir.
- Delivery: The oxygen is delivered to the patient via a nasal cannula or oxygen mask at the prescribed flow rate.
This cycle repeats continuously, ensuring a steady stream of oxygen without the need for heavy tanks or chemical reactions.
Benefits of Choosing EverFlo for Home Therapy
The EverFlo oxygen concentrator offers several distinct advantages for Sydney-based users who require stationary oxygen therapy:
- Exceptional Reliability: Designed with fewer moving parts than its competitors, the EverFlo is engineered for 24/7 continuous operation.
- Low Maintenance: For most users, the internal filters only need to be serviced every two years, significantly reducing the cost of ownership.
- Energy Efficiency: Consuming only 350 watts, it is one of the more energy-efficient 5-LPM units available, helping to keep Australian electricity bills manageable.
- Quiet Operation: At 45 decibels, it is quiet enough to be used in a bedroom without disrupting sleep for the user or their partner.
- Ease of Transport: The integrated top handle and four smooth-rolling wheels make it easy to move the unit from the living room to the bedroom.
Step-by-Step Guide: Setting Up Your EverFlo
If you have recently acquired an EverFlo oxygen concentrator, follow these steps to ensure safe and effective operation:
1. Placement
Place the unit in a well-ventilated area. Ensure there is at least 15–30 cm of space between the machine and walls, furniture, or curtains. Never place the unit in a closet or a small, unventilated room, as it needs fresh air to concentrate oxygen and must disperse heat.
2. Connection
Plug the power cord directly into a wall outlet. Avoid using extension cords or power strips, as these can cause voltage drops that may trigger the device’s alarms.
3. Adding Humidity (Optional)
If your doctor has prescribed humidified oxygen:
- Fill the humidifier bottle with distilled water to the “Max” line.
- Attach the bottle to the velcro strap on the back of the unit.
- Connect the humidifier tube from the bottle to the oxygen outlet port.
4. Powering On
Flip the power switch to the “I” (On) position. All lights (Red, Yellow, Green) will flash, and a brief alarm will sound. This is a self-test. After a few seconds, only the Green light should remain illuminated.
5. Adjusting Flow
Turn the flow meter knob until the ball is centered on the line corresponding to your prescribed Litres Per Minute (LPM). Do not change this setting unless instructed by your healthcare professional.
Essential Maintenance and Cleaning Best Practices
To keep your EverFlo oxygen concentrator running at peak performance in the dusty or humid conditions sometimes found in Australian coastal cities like Sydney, follow this maintenance schedule:
Weekly Cleaning
- Exterior: Wipe the outside of the unit with a damp cloth and a mild household cleaner. Ensure the unit is unplugged before cleaning.
- Gross Particle Filter: If your unit is fitted with an external foam filter (located at the back), remove it, wash it with warm soapy water, rinse thoroughly, and let it air dry completely before reinserting.
Monthly Tasks
- Cannula Replacement: Replace your nasal cannula every 2–4 weeks to prevent bacteria buildup and ensures optimal flow.
- Tubing Check: Inspect your oxygen supply tubing for kinks or cracks.
Professional Servicing
The internal intake filter should be replaced by an authorized technician every 24 months. In Sydney, many medical equipment providers offer annual “health checks” for concentrators to verify oxygen purity levels using a calibrated analyzer.
Common Mistakes to Avoid
- Smoking Near the Device: Oxygen is an accelerant. Never smoke or allow open flames (candles, gas stoves) within 3 meters of the concentrator.
- Blocking Air Vents: Covering the unit with a towel or placing it against a thick carpet can cause it to overheat and shut down.
- Using Tap Water: Always use distilled water in your humidifier bottle. Tap water contains minerals that can clog the internal components of the bottle and tubing.
- Ignoring Alarms: If the Red or Yellow light stays on, switch to your backup oxygen source immediately and contact your provider.
FAQ: EverFlo Oxygen Concentrator in Australia
What do the lights on my EverFlo mean?
The Green light indicates the unit is functioning correctly. A Yellow light suggests a low oxygen condition or a maintenance requirement (the unit is still safe to use but needs attention). A Red light indicates a system failure or extremely low oxygen purity; you must switch to backup oxygen immediately.
Can I use the EverFlo 24 hours a day?
Yes. The EverFlo is designed for continuous 24/7 operation. Many patients in Sydney use it throughout the night for sleep and during the day for stationary activities.
Does the EverFlo come with a warranty in Australia?
Most reputable Australian retailers provide a 3-year limited warranty on new Philips EverFlo units. Always check with your local Sydney supplier for specific warranty terms.
Is the EverFlo portable?
While it has wheels and a handle, the EverFlo is a stationary concentrator and requires a wall outlet. For travel outside the home, you would need a Portable Oxygen Concentrator (POC) like the Philips SimplyGo.
How much does it cost to run an EverFlo in Sydney?
Based on average NSW electricity prices, running a 350W device for 10 hours a day typically costs around $0.80 to $1.20 per day, depending on your specific energy tariff.
Conclusion
The EverFlo oxygen concentrator remains a premier choice for home oxygen therapy in Sydney due to its balance of performance, quiet operation, and low maintenance requirements. By following the setup and cleaning protocols outlined in this guide, you can ensure your device provides reliable support for your respiratory health for years to come.
If you are experiencing issues with your current unit or are ready to upgrade to a more efficient system, the next step is to consult with a local specialist.
