Don't listen to all of these naysayers. This is a great disinfecting system. My water chamber, mask, and hose all fit in the back with room to spare. I do not recommend putting the actual machine in. I have a ResMed AirSense 10 AutoSet and there is a video on YouTube to show you how to clean the unit itself. I bought my Clean Zone system at Walmart and it is one of the best purchases, same outcome as those high-priced systems that make you think that they are better in quality. The only issue that I have with this is that the unit takes FOREVER to charge. Other than that, put your pieces parts in the included plastic bag along with the unit and in 90 minutes you are good to go. I set my calendar to remind me to sanitize every Saturday morning.
Bottom Line: Yes, I would recommend this to a friend
