Dishwasher-Safe Water Tub

Very easy to take apart, the ResMed S9 H5i Cleanable Water Tub can be disassembled effortlessly and is dishwasher safe to provide better hygiene for your CPAP therapy. Regular maintenance of the ResMed H5i Cleanable Water Tub can increase the lifespan, requiring a replacement typically after two years of use. Distilled water is recommended for all CPAP humidifiers to prevent calcium buildup, and if you choose to hand wash, warm water with a mild detergent such as baby shampoo works best. Clean and maintain your ResMed humidifier chamber and all CPAP therapy equipment like tubes and masks regularly.

Climate Control

With its ClimateLine technology, the heated humidifier allows for all the parts of your ResMed set to work together with the five ClimateLine sensors to provide superior climate control throughout your CPAP therapy. The tubing has a mask sensor built in to control the temperature of the airflow into the mask at all times, so that the temperature at the mask is the same as the temperature that enters the tube, providing constant relief. The sensors around the humidifier are highly sensitive and can automatically adjust the temperature so that they can monitor the ambient temperatures and adjust accordingly to prevent rain out in the tube and mask.

Key Features

  • Dishwasher Safe Water Tub - Easy to disassemble and quick to clean
  • Compatible - Works with any ResMed S9 CPAP Machine
  • Climate Control - Provides consistent comfort ignoring ambient conditions

Reviewers Tip:

The ResMed S9 H5i humidifier comes with a new warm-up feature that allows you to warm up the humidifier to your preferred temperature beforehand so that when you are ready to begin your CPAP therapy the humidifier is already heated up and can provide the maximum and preferred amount of comfort. Navigate your display so that the Humidity Level icon is showing, then preheat the humidifier by holding the push dial down for three seconds. There will be a progress bar that says "Warming Up" which tells you how long until the humidifier reaches the temperature desired.

Disassembly of the Water Tub


What are the benefits of having humidification with your CPAP machine?

Humidifiers are a comfortable option for CPAP therapy. While not preferred by everybody, we recommend a humidifier in extreme climates or areas where the air is either cold or wet. Some CPAP users can experience dry mouth, or a dry nasal area, after CPAP use, and humidifiers can help reduce or completely eliminate the discomforts that come as a side effect of storing your CPAP machine in an area where the ambient temperatures can affect the comfort levels. Humidifiers will not affect the CPAP performance.

What's the best way for extending the life of my tub?

With regular maintenance, your tub can last up to two years before it needs to be replaced. This tub can be easily dissembled and put into a dishwasher to help the process, but it is not the only way to extend the life of your water tub. As with any humidifier and water tub, distilled water is always recommended over tap water. Tap water can lead to calcium build-up, among other things, in the tub, while distilled water can help prevent these types of build-ups. Tap water is still usable, but it will require you to replace the water tub more frequently.

I just got this tub and it's awesome. My standard tub was hard to clean since I couldn't get inside it. I rinsed it out ever day, used only distilled water and soaked it in vinegar and water once a week. I did that for 3 months when I noticed algae growing in the bottom and I freaked! I immediately got online and bought a washable tub. It's been great. I just pop it on the top shelf of my dishwasher and it comes out spotless. I wish I had known about this tub when I bought my S9.

Subject: Cleanable Water Chamber
This was my first time ordering from this company. I ordered a replacement Cleanable Water Chamber for my CPAP machine. Within about two hours, I received an email stating that my order had been shipped, and two days later I received it! Such quick customer service! I would definitely recommend this company, and in the future will order from them if I need anything for my CPAP machine.

I bought two H5i Cleanable Water Chamber. Both of them are original products.. Easy to clean everyday..
By the way, if your H5i waits for a long time at close position without using it, you may have difficulty to detach all three parts..
Don't give up. It can be detached at the end with the aid of warm water a little bit...

It's good to be able to open up the parts and clean them now and then. My other one was a sealed water chamber, so it's hard to clean it thoroughly. It works great. And I can throw it in the dishwasher when I don't have time to hand wash it.
