I use the regular water container when I travel because i do not want the extra hassle of aking my So Clean through airport security. When I get home I just replace the top of the container with this top and I am automatically attached to my so clean
I use the SoClean daily and it makes me feel that my BiPap is safe and clean. It cleans my entire system automatically and I have seen no negative effect on my memory foam face cushions. Great System.
