ResMed HumidAir Standard Water Tub for AirSense 11

This is the standard water tub for the humidifier built into every ResMed AirSense 11. Your machine warms the water it holds and blends that moisture into your therapy air, which can make a long night of CPAP easier on your nose and throat.

It fits the AirSense 11 AutoSet, CPAP and Elite, along with the AirCurve 11 VAuto, S and ASV bilevels. In the box is one HumidAir 11 standard tub, ResMed part 39100, with a white thumb grip on the lid.

Key features:

• Holds a night's water: ResMed's own testing at room temperature puts a full tub at more than eight hours before it needs topping up.
• Dishwasher safe: ResMed's North American guide for AirSense 11 allows it, provided the temperature stays at 55 C or lower.
• Distilled water only: ResMed specifies distilled water at room temperature for the standard tub, never hot water, and no scented oils or additives.
• Built for Climate Control: Attach a ClimateLineAir 11 heated tube and your machine can manage tube warmth and humidity together on its own.
• Loads from the side: Open the lid to fill it, close it again, and the tub slots into the machine's side panel.
• Single-patient design: One person can keep using it night after night, though ResMed says it can't be reprocessed between different users.

Choose the standard tub if your AirSense 11 is yours alone and you're happy to keep distilled water on hand. If you'd rather use ordinary drinking water and keep one tub for years, the HumidAir 11 cleanable tub fits the same machines.

Note: This tub won't fit an AirSense 10 or AirCurve 10. Those machines take the original HumidAir tub, a different ResMed part, so check the model name on your machine before ordering.
