Home Oxygen Concentrators — When You Need One And How To Choose
The difference between a concentrator and a cylinder, how to pick the capacity, and the basic safety rules.

When A Doctor Recommends Home Oxygen
Home oxygen is a prescribed treatment, not a retail purchase. It is usually recommended after a severe chest infection, for COPD patients, or during palliative care.
The doctor will set a flow rate in litres per minute, for example "2 LPM". Never raise that setting yourself without medical advice — too much oxygen can be harmful for some patients.
Concentrator Or Oxygen Cylinder
Both deliver oxygen, but they work very differently and that affects the long-term cost.
| Concentrator | Oxygen Cylinder | |
|---|---|---|
| Source | Filters room air | Compressed oxygen |
| Supply | Continuous while powered | Needs refilling |
| Recurring cost | Electricity bill | Refill charges |
| During a power cut | Stops working | Still works |
Many families run a concentrator as the main supply and keep one small cylinder as an emergency backup.
Choosing The Right Capacity
Concentrators are sold by maximum flow. Pick a model whose maximum comfortably exceeds the prescription, so the machine is not running at its limit all day.
- 5 LPM — enough for most home use
- 8 to 10 LPM — for high-flow requirements
- Portable models — for patients who still go out
Safety And Maintenance
- No smoking or open flame within two metres
- Keep the machine at least 30cm from the wall for ventilation
- Wash the external filter weekly and dry it fully
- Check the tubing is not kinked or trapped under the bed
- Use a distilled-water humidifier if the patient’s nose gets dry
Stand the machine on a level floor away from thick carpet, which can block the air intake underneath.
