It's just a humidifier tank, use distilled water and keep a filter on the PAP device, it won't need a regular cleaning. I've had three tanks (sealed) total for my Fischer Paykel device that I've had for 20 years but the first two were somewhat fouled by occasional use of tap water. You do what you must.

I've an S8 Elite CPAP with humidifier for five years and it's just fine with the original tank. Pristine.

Four stars for build quality, but I'll be buying the dishwasher safe version for a replacement, just so I can use reverse osmosis water that isn't as mineral free as supermarket distilled water. If I need to.

I really do not know how will be designed to not be able to take apart for clean, very inconvenient and not hygiene. Now I'm considering to buy a Cleanable Water Tub, It,s extra expense .

I agree, What good is it if you can only superficially clean. Pneumonia bacteria hide in the cracks and crevices inside the unit. Very unsafe. should be discontinued

I agree with all of the former posters, the machine originally came with this type of humidifier tub and I couldn't wait to get rid of it.

Stay away from it

HOW ARE YOU SUPPOSE TO CLEAN THE INSIDE OF THIS SEALED WATER CHAMBER! it would be easier for people to use if they can clean. USELESS!

How is this dishwasher safe if you cannot take it apart? The seal makes it impossible to do this.
