Oxygen Concentrators

Oxygen concentrators in Australia: how to choose the right option

If your clinician has prescribed oxygen therapy, the right concentrator depends on how you'll use it: at home, on the move, or short-term. Mega Medical stocks portable and stationary oxygen concentrators, plus genuine accessories and spare parts to keep your unit running well.

Portable vs stationary: which fits your day-to-day?

• Portable oxygen concentrators suit people who need a lighter setup for outings, appointments, and travel.
• Stationary oxygen concentrators suit home or clinical use where you want a stable, plug-in unit for longer sessions.

A simple way to decide:

• Choose portable if weight and battery time matter most.
• Choose stationary if you want home comfort and plug-in reliability.
• Consider hiring if you want a short-term solution or want to trial a setup before you buy.

Flow settings explained

You'll see two common delivery types:

• Continuous flow: delivers a steady stream, often shown in litres per minute (L/min).
• Pulse dose (pulse flow): delivers oxygen in bursts as you breathe in.

Important: on many portable devices, the setting number is not the same as litres per minute. The amount delivered depends on the device and your breathing rate. If you're unsure what you need, contact Mega Medical and we'll help you choose a suitable model.

What specs matter when comparing models

• Delivery type: continuous flow vs pulse dose
• Output range: match the unit to your prescribed requirement
• Battery options: standard vs extended, plus spare batteries for longer outings
• Weight and carry style: shoulder carry vs trolley
• Noise level: useful for shared spaces or overnight use
• Power options: AC plug and car charger compatibility
• Filters and routine care: how easy it is to clean or replace filters
• Alarms and indicators: clear alerts and simple controls
• Service and warranty: long-term support matters as much as the device

Accessories that make setup easier

• Extra battery or extended battery for longer time away from a power point
• Carry bag or protective cover for portability and storage
• Spare filters to simplify maintenance
• Humidification options (only if compatible with your setup)
• Power supplies and chargers, including car charging where relevant

Compatible accessories are available in our Oxygen Concentrator Accessories & Parts range.

FAQ

What should I ask my clinician before buying a concentrator?

Ask what flow type you need, your required setting or range, and when you need oxygen (rest, walking, sleep). Also ask whether you need portable use, any target oxygen saturation, and whether a humidifier is recommended. Confirm the concentrator type matches your prescription.

What accessories do I need on day one?

Start with a carry bag or case, spare filters, and the right power options. For portable models, a spare battery is usually the first add-on that makes life easier.

How often do filters need cleaning or replacing?

Check filters weekly, clean washable filters as the manual directs, and replace them when worn, clogged, or past the recommended interval. Always follow the product instructions.

What should I check first before comparing two concentrators?

Confirm each unit meets your needs for delivery type and output range. If that matches, compare weight, battery options, noise level, power and charging, and warranty support.

What's the real difference between pulse dose and continuous flow?

Continuous flow delivers oxygen steadily. Pulse dose delivers oxygen in bursts when you inhale. Pulse dose can help with portability and battery life, but it's not a constant stream. The right choice depends on your prescription and when you use oxygen.

How loud is quiet enough for bedroom use?

Look for a model described as low-noise and check the dB rating if listed. Check where the air intake sits and whether the unit has a smooth fan sound rather than rattles. Place it with good ventilation, not against a wall.

What's a sensible battery target for errands vs a full day out?

For short errands, aim for enough runtime to cover the outing plus a buffer. For a full day, plan for extended battery options or a spare battery, and a way to recharge in the car or at mains. Battery life changes with settings, so use the runtime estimate for your typical use.

Can I charge a portable concentrator in the car?

Many can. Confirm the unit supports DC or car charging, you have the correct approved charger, and your vehicle outlet can handle the power draw. Avoid generic adapters unless the manufacturer allows them.

How long do concentrators last with regular care?

With normal use and regular cleaning, many concentrators last several years. Lifespan depends on run hours, filter care, and servicing. Check the warranty, service options, and whether key parts are easy to replace.
