Philips Respironics
SimplyGo Humidifier Bottle Connector
If you use humidifier bottles with your SimplyGo portable oxygen concentrator, you'll need to pick up one of these Connectors. Simple to use, the Connector does exactly that - connects your humidifier bottle to the outlet of your concentrator, then to a nasal cannula which goes to your nose.
Pick up a spare so that you're never without your humidification. And don't forget the bottles while your at it!
