An oxygen concentrator takes in room air, removes most of the nitrogen and delivers concentrated oxygen through a nasal cannula. It runs on electricity and never needs refilling, so for a patient who needs oxygen for many hours a day it is usually the most practical choice. Here is how to choose one in Bangladesh.
In short
- Choose by the prescribed flow: a 5 litre machine for up to 5 L/min, a 10 litre machine for higher flows.
- Look for an oxygen purity of around 93% at the flow you need, and an oxygen purity indicator or alarm.
- Plan for power cuts: use an IPS or voltage stabiliser, and keep an oxygen cylinder as backup.
5 litre or 10 litre?
A 5 litre concentrator delivers up to 5 litres per minute and suits most home patients. A 10 litre machine is for patients prescribed a higher flow, for example some COPD or post-COVID patients. A 10 litre machine is larger and uses more electricity, so do not buy a bigger machine than the doctor prescribes.
What to check before you buy
Oxygen purity
Home concentrators typically deliver around 93% oxygen, plus or minus 3%, at their rated flow. A purity indicator or low-oxygen alarm tells you if the machine is not performing.
Noise
The machine often runs all night in the patient’s bedroom. A quieter model, such as the Konsung KS-5, makes a real difference to sleep.
Alarms and timer
Useful alarms include power failure, low oxygen purity and high temperature. A timer helps when the patient needs oxygen for set hours.
Power and load-shedding
A concentrator stops when the power stops. Use a good voltage stabiliser to protect it from voltage swings, an IPS if you have long power cuts, and keep a cylinder ready as backup.
Service and parts
Filters need regular cleaning, and machines need servicing. Buy a brand with spare parts in Bangladesh, and from a seller who repairs what they sell. Sed Bangla offers concentrator repair in Dhaka.

Using a concentrator safely
- Place it at least 30 cm from walls and curtains so air can flow, and away from heaters, stoves and smoking.
- Wash the air filter as the manual says, usually every week.
- Fill the humidifier bottle with clean or distilled water only to the marked line, and change the water daily.
- Never change the flow setting without the doctor’s advice.
