Firstly, you need to position the oxygen concentrator at least 1 to 2 feet far from the wall and other furniture items. The reason is the device requires adequate space to efficiently circulate air. If prescribed, you can connect the humidification bottle. The same is needed in case the oxygen flow rate is more than 2-3 liters/minute.
Make sure to connect the oxygen tubing to an adapter or the humidification bottle. An inlet filter is available to clean the air. Therefore, make sure the filter is installed before using the
concentrator. Keep in mind to turn on the unit at least 15-20 minutes before its operation.
