A straightforward, essential replacement that ResMed recommends completing every six months.

Key Features

Genuine ResMed replacement tub: Designed specifically for the HumidAir humidifier integrated into AirSense 10 and Lumis devices. Genuine parts ensure correct fit, proper sealing, and consistent humidification performance — protecting both your therapy quality and your device warranty.
Single-use design: The standard tub can be hand washed with warm water between uses, but is not dishwasher safe. ResMed recommends replacing it every six months regardless of cleaning, or sooner if you notice discolouration, mineral build-up, or any reduction in humidifier performance.
Easy to replace: Slides in and out of the HumidAir humidifier without tools — a quick, straightforward swap that takes seconds and requires no technical knowledge.
Maintains therapy comfort: A fresh tub ensures consistent water delivery and prevents the reduced humidity output, musty odours, or mineral residue that can develop in an ageing water chamber.

Who Is This For?

This tub is compatible with the full AirSense 10 range — including the AirSense 10 AutoSet, AirSense 10 AutoSet for Her, AirSense 10 Elite, and AirSense 10 CPAP — as well as the AirCurve 10 and Lumis series devices. If you prefer a reusable option that can be washed in the dishwasher and replaced less frequently, the HumidAir Cleanable Tub (Version II) is available as an alternative. For a full overview of when to replace your CPAP consumables, refer to the CPAP Club CPAP replacement schedule. If you're also experiencing tube condensation or rainout, the ResMed ClimateLineAir heated tube works alongside the HumidAir humidifier to eliminate that issue entirely.

Product FAQs

What is the difference between the HumidAir Standard Tub (37299) and the HumidAir Cleanable Tub (37471)?

The key difference is dishwasher compatibility. The Standard Tub (37299) is hand wash only and is a single-use disposable chamber — ResMed recommends replacing it every six months. The Cleanable Tub Version II (37471) is dishwasher safe, making it easier to clean thoroughly on a regular basis, and is designed to last up to 12 months before replacement. Both tubs are compatible with the same AirSense 10 and Lumis series devices and deliver identical humidification performance.

Which tub should I choose — the Standard or the Cleanable?

It comes down to how you prefer to maintain your equipment. If you'd rather simply replace your tub every six months without worrying about cleaning it, the Standard Tub (37299) is the more straightforward option. If you prefer the convenience of putting your water chamber in the dishwasher for a thorough clean and want a tub that lasts up to 12 months, the Cleanable Tub Version II (37471) is the better choice. Both options keep your humidifier hygienic and performing correctly — the difference is dishwasher compatibility and how long each tub is designed to last.

Can I wash the Standard Tub (37299)?

The Standard Tub can be hand washed with warm water, but it is not dishwasher safe — the heat and detergents in a dishwasher can damage the tub and compromise its seal. If you want a tub you can clean in the dishwasher, the HumidAir Cleanable Tub Version II (37471) is the correct option for your device.

How often should I replace my HumidAir tub?

ResMed recommends replacing the Standard Tub (37299) every six months. For the Cleanable Tub Version II (37471), ResMed recommends replacing it every 12 months — though you should replace it sooner if you notice any cracking, discolouration, persistent odour, or difficulty sealing. For a full guide on when to replace all your CPAP consumables, refer to the CPAP Club CPAP replacement schedule.

Are both tubs compatible with my AirSense 10 or Lumis device?

Yes. Both the Standard Tub (37299) and the Cleanable Tub Version II (37471) are compatible with the full AirSense 10 range — including the AirSense 10 AutoSet, AutoSet for Her, Elite, and CPAP — as well as the AirCurve 10 and Lumis series devices. Either tub will fit and function correctly in your HumidAir humidifier.

Is the Cleanable Tub Version II different from the original Cleanable Tub (37300)?

Yes — the Version II (37471) replaces and supersedes the original Cleanable Tub (37300). It features an updated material and manufacturing process for the lower section of the tub, improving its reliability and resistance to cracking over time. Humidification performance and water capacity are unchanged. If you previously used the original Cleanable Tub (37300), the Version II is the correct current replacement.
