A manually filled chamber empties during the session, forcing a stop to add water. The myAIRVO 2 auto-fill chamber, on the other hand, connects to a water bag, and the liquid flows down as the level drops.

• The water level remains constant from the beginning to the end of the session, without mid-session checks
• The water bag provides access to a larger volume, useful for prolonged treatments
• The dual float acts as a safety feature, preventing both overflow and the chamber from running dry
