Resmed HumidAir™ 11 Cleanable CPAP Water Tub for AirSense 11

Why the HumidAir 11 Water Tub Is Worth Replacing on Schedule

The water chamber is the most handled component in any CPAP setup — filled nightly, cleaned regularly, and subject to mineral deposits, discolouration, and eventual wear on the metal heating plate. A degraded chamber compromises humidification performance directly: scaling on the heating plate reduces heat transfer efficiency, meaning less moisture reaches the mask even with humidity settings maxed out. The HumidAir 11 is the only cleanable, reusable chamber certified for the AirSense 11 series — it seats precisely into the integrated humidifier bay and connects to the Climate Control and ClimateLineAir 11 heated tubing system, enabling the machine's automatic humidity regulation to function as designed. The 380 mL capacity supports a full night of therapy for most users without mid-session refilling, and the dishwasher-safe construction (top rack) makes daily hygiene straightforward.
