ResMed HumidAir™ 11 Water Tub — Overview
The HumidAir™ 11 Water Tub is the genuine replacement chamber for the AirSense 11 and AirCurve 11 integrated humidifier. Two variants are available: the Standard tub (opaque, hand wash only) and the Cleanable tub (clear, top-rack dishwasher safe with removable parts for thorough cleaning). Both hold 380mL — enough for a full night without refilling. The AirSense 11 automatically detects the chamber when inserted and prompts humidification settings. Always use distilled water only — tap water causes mineral deposits that shorten equipment life and can promote bacterial growth. Replace every 6 months.

⚠️ Distilled water only. Tap water deposits minerals that build up in the chamber and tubing, promote mould, and shorten equipment life. Standard tub is NOT dishwasher safe — hand wash only.
Which variant should I choose — Standard or Cleanable?
The Cleanable (clear, dishwasher-safe) tub is worth the slightly higher price for easier hygiene maintenance. Standard suits patients who prefer hand washing and don't mind the opaque design.
