Oxygen concentrator
There are four important factors to consider when purchasing an oxygen concentrator:
- Oxygen concentration
- Flow rate/litres per minute
- Noise level
- Power supply
The ideal oxygen concentration is between 87% and 99%.
Flow rate: For home use, an oxygen flow rate of 2 litres per minute is usually sufficient. However, some conditions require a higher flow rate. Concentrators are available with flow rates of up to 10 litres per minute.
The noise level of an oxygen concentrator is usually between 31 and 60 decibels (dB), comparable to a quiet conversation or normal speech. Some brands even produce even quieter models.
Power supply type: Oxygen concentrators are usually connected to the mains for continuous use.
Prices for stationary oxygen concentrators start at €625 for a 5-liter unit and go up to €2016 for a 10-liter oxygen concentrator.
