Why AirSense 11 Water Capacity is Necessary
From my experience using the AirSense 11, the water capacity is a crucial feature that makes a big difference in my nightly comfort. Having a sufficient water capacity means I don’t have to refill the humidifier chamber constantly, which is especially convenient during busy mornings or late nights when I’m tired. It allows me to go through the entire night without interruptions, ensuring consistent humidification.

With the AirSense 11, the water tank size strikes a great balance, providing enough moisture to keep my airway comfortable all night long.
Overall, the water capacity is more than just a number—it directly impacts how effective and hassle-free my CPAP therapy is. It’s one of those features I truly appreciate because it supports uninterrupted, restful sleep.
