Oxygen Concentrator vs Oxygen Cylinders: Which Is Better for Home Oxygen Therapy in Australia?

If you've been prescribed home oxygen therapy in Australia, you'll face a choice between two delivery methods: oxygen cylinders or an oxygen concentrator. Your respiratory specialist may have recommended one or left the decision to you. This guide gives you a clear, honest comparison of both options so you can make the right call for your situation.

How Each System Works

Oxygen Cylinders

Compressed medical oxygen is stored in steel or aluminium cylinders and delivered to you by a supplier. You connect a regulator, set the flow rate, and breathe through a nasal cannula or mask. When the cylinder empties, you swap it for a full one — either from your own stock or via a scheduled delivery.

Oxygen Concentrators

A concentrator plugs into a standard 240V power point and extracts oxygen from the room air around it — removing nitrogen through a molecular sieve to produce a continuous supply of concentrated oxygen at 87–95% purity. No deliveries. No cylinders. As long as it's plugged in, it runs.

Cost Comparison — The Real Numbers

This is where most people are surprised. The upfront cost of a concentrator looks significant. The ongoing cost comparison changes the picture entirely.

Oxygen Cylinders — Ongoing Costs

Cylinder costs vary by supplier, location, and usage volume, but for a patient using 2 L/min for 16 hours per day:

• Cylinder rental: $20–40/month
• Refill costs: $80–$150/month depending on consumption
• Delivery fees: $20–50/month depending on location and frequency
• Total: $1,440–$2,880 per year
• 5-year cost: $7,200–$14,400

Oxygen Concentrator — Total Cost of Ownership

• Purchase price (Yuwell 8F-5A 5L): $1,100
• Electricity: approximately $250–$350 per year at Australian residential rates
• Filter replacement: $50–$100 per year
• Annual service: $100–$250 per year
• Year 1 total: $1,500–$1,800
• 5-year total: $2,800–$4,500

For a patient using 4+ hours of oxygen per day, a concentrator typically pays for itself within 12–18 months compared to ongoing cylinder costs. The 5-year saving is $4,000–$10,000 or more depending on usage.

Practical Comparison

When Cylinders Are Still the Right Choice

Cylinders aren't always the wrong answer. There are situations where they make sense:

• Short-term oxygen therapy — post-operative or acute illness oxygen for a few weeks. Buying a concentrator isn't justified for a short prescription.
• Power outage backup — most concentrator users keep one small cylinder as emergency backup for power failures. A concentrator is not suitable as the sole oxygen source for patients in areas with frequent outages.
• Travel and mobility — if your prescription requires oxygen while moving around outside the home, a portable concentrator or travel cylinder may be needed alongside your home unit.
• Very low usage — if you use oxygen for only 1–2 hours per day, the economics of a concentrator are less compelling. Run the numbers for your specific usage level.

When a Concentrator Is Clearly Better

• You use oxygen for 8+ hours per day or overnight
• You're on a long-term (LTOT) prescription
• You live more than 30 minutes from your supplier
• You've experienced delivery delays or run out of oxygen unexpectedly
• You want to eliminate the ongoing cost and logistics of cylinder supply

Which Concentrator?

Your choice of concentrator depends on your prescribed flow rate. Confirm with your respiratory specialist before ordering:

• Yuwell 8F-3W — 3 Litre ($849): For prescribed flow rates of 1–3 L/min. Quieter and more compact than the 5L model.
• Yuwell 8F-5A — 5 Litre ($1,100): For prescribed flow rates up to 5 L/min. Covers the majority of LTOT prescriptions. Intelligent purity alarm if output drops below clinical threshold.

Both are TGA-approved and sold by NATA-certified biomedical engineers who test and service oxygen concentrators for hospitals and aged care facilities. For more on managing your respiratory condition at home, read our COPD home equipment guide.

Do I Need a Prescription?

Oxygen concentrators are medical devices prescribed by a respiratory physician or GP. While a prescription is not legally required to purchase a concentrator, your doctor needs to specify your flow rate and duration for therapy to be safe and effective. Never start or change oxygen therapy without medical guidance — supplemental oxygen at the wrong flow rate can be harmful in some respiratory conditions.
