ResMed HumidAir Standard Water Tub for AirSense 10

This is the everyday water tub for the HumidAir humidifier on a ResMed AirSense 10. It holds the water your machine warms through the night, adding moisture that can ease the dryness CPAP air sometimes brings to your nose and throat.

It fits AirSense 10 AutoSet, AutoSet for Her, Elite and CPAP models, plus the AirCurve 10 VAuto, S and ST bilevels. You get one standard tub, ResMed part 37299, ready to drop straight into your machine.

Key features:

• Room for a full fill: It holds 380 mL when filled to the maximum mark, using room-temperature distilled water as ResMed specifies.
• Slides in from the side: The tub fits into the side of the AirSense 10, and a gentle press at its top and bottom releases it again.
• Unlocks Climate Control: With ClimateLineAir heated tubing attached, the humidifier and tube work together to keep warmth and moisture steady automatically.
• Simple six-month swap: The standard tub is designed for six months of use, so replacing it twice a year keeps a fresh one in rotation.
• Made for one sleeper: ResMed designs the standard tub for single-patient home use, and a contaminated one gets replaced rather than disinfected.
• Hand-wash only: That's ResMed's rating in its North American user guide, the edition that carries the Canadian approvals.

It suits AirSense 10 users who are happy to look after a tub by hand and replace it on a steady schedule. If you'd rather own a tub that comes apart and lasts for years, compare the cleanable version, which fits the same machines.

Note: This tub does not fit the AirSense 11 or AirCurve 11, which take the HumidAir 11 tub. Check that the label on your machine says AirSense 10 or AirCurve 10 before ordering.
