Why the Right Concentrator Matters

An oxygen concentrator is a long-term investment in your health, so choosing the right model is important. The best device for you depends on your prescribed oxygen needs, your lifestyle, and your home environment. This guide walks you through the key factors to compare.

1. Flow Rate (5L vs 6L and Beyond)

Flow rate is the amount of oxygen delivered per minute, measured in litres per minute (LPM).

  • 5L concentrators suit most home users with mild to moderate oxygen needs.
  • 6L concentrators are better for higher-dependency patients or those prescribed higher flow rates.
  • Always match the device's maximum flow to your doctor's prescription, with some headroom.

2. Oxygen Purity

Medical-grade concentrators should deliver 90–95% oxygen purity. Look for a model that maintains stable purity even at its highest flow setting — a quality indicator of the compressor and sieve beds.

3. Continuous Flow vs Pulse Dose

  • Continuous flow: Delivers a constant stream of oxygen — ideal for home and night-time use.
  • Pulse dose: Releases oxygen when you inhale — common in portable units for active users.

4. Noise Level

Since concentrators often run for hours, a quiet unit (≤45 dB, ideally below 40 dB) greatly improves comfort, especially during sleep.

5. Portability and Size

Stationary home units are larger but powerful, while portable models offer mobility for travel and errands. Consider where the device will live and whether you need to move it often.

6. Running Costs and Reliability

  • Check power consumption — most units use 300–400 watts.
  • Look for energy-efficient technology to keep electricity bills low.
  • Choose a brand with warranty, genuine spare parts, and accessible service centres.
