Choosing the right oxygen concentrator starts with understanding your prescribed flow rate. Most home patients require between 1–5 litres per minute (LPM), but patients with severe COPD or interstitial lung disease may need up to 10 LPM. Always match the concentrator's maximum flow capacity to your clinician's prescription — never compromise on this.
Oxygen purity is equally critical. A clinical-grade concentrator should deliver 93% ±3% purity at its rated flow. Below 87% purity provides inadequate therapy. Look for devices with an integrated O₂ concentration alarm that alerts you if purity drops — this feature is non-negotiable for home use.
Noise levels matter for sleep quality and caregiver comfort. Premium concentrators operate below 45 dB — roughly the sound of light rainfall. If the device will be used in a bedroom, prioritise models with a night-quiet mode. Some older or budget models can exceed 50 dB, which disrupts sleep over long-term use.
Power consumption and portability are the final factors. A standard 5L concentrator draws 150–300W continuously. For patients in areas with frequent power cuts, pairing the unit with a pure-sine-wave inverter and battery backup is advisable. For travel, ask your supplier about lightweight portable models with carry handles and airline-approved documentation.
