Description
Quick answer: This is the genuine ResMed cleanable water tub for the HumidAir heated humidifier (part 37479), used with the Air10 series — AirSense 10 and AirCurve 10. It’s the reservoir that holds the water your humidifier heats to add moisture to your airflow. Unlike the standard tub, the cleanable version opens up so every internal surface can be washed thoroughly and reused — a practical long-term choice if you’d rather deep-clean than replace.

About this part
The HumidAir humidifier is built into the AirSense 10 and AirCurve 10. It warms water in the tub so the air delivered through your tubing carries moisture — which helps prevent the dry mouth, dry nose, and nasal irritation that unhumidified therapy can cause. It also works together with ClimateLineAir heated tubing (if fitted) to keep humidity consistent all the way to the mask.
ResMed makes the HumidAir tub in two versions. The standard tub is a sealed unit, replaced periodically. This cleanable tub is designed to be opened, so you can wash all internal surfaces and keep using it over a longer period — higher cost up front, replaced less often.
It’s still a wear item: even a cleanable tub eventually clouds, scales up, or stops sealing properly, and should be replaced when it does.

Care & replacement
Empty the tub daily and refill with fresh distilled water before each use — distilled water greatly reduces mineral scale and extends the tub’s life. Clean it according to the HumidAir instructions (the cleanable design gives access to all internal surfaces), and let it dry completely before reassembly. Check the seal each time you put it back together. Replace the tub if it becomes cloudy, heavily scaled, cracked, or no longer seals properly.
Frequently asked questions
What’s the difference between the cleanable tub and the standard tub?
The cleanable tub opens so it can be washed thoroughly and reused; the standard tub is a sealed unit replaced periodically.
Which devices does it fit?
Devices with the HumidAir humidifier on the Air10 platform — AirSense 10 and AirCurve 10.
Will it fit my AirSense 11?
No — the Air11 series uses a different tub (HumidAir 11, part 39101). Contact us if you’re unsure which platform you have.
What water should I use?
Distilled water is recommended — it reduces mineral buildup and helps the tub last longer.
When should I replace it?
When it becomes cloudy, heavily scaled, cracked, or no longer seals properly.
Do I need a prescription?
No — replacement humidifier parts do not require a prescription.
Can I get it delivered in Brooklyn or shipped nationwide?
