    Good solution for my CPAP on short trips

    I bought this for my AirSense 11 CPAP when I go on short trips so I don't have to bring distilled water with me; I just stick this in, and I just have plain air. I tried it out at home with zero issues so I know I could go 1-3 days without water.

    Perfect for when you don't want to lug around water

    This side cover replaced the water tank (side cover) so that the unit remained useable without needing to add the water. I was having big problems with the water as it was constantly building up in the hose and the face mask and waking me up - trying to get the hose to dry out was also a problem . Additionally, having to locate water during travel was a hassle. This solved both problems. I just recently received the side cover and so far so good - I may alternate between the two because my sinuses seem to be more dried out when I don't use the water. At least I have options and was very happy to learn of this attachment for the unit (I could only locate this item on the Sleep Doctor site) and they delivered fairly quickly.

    Robert's Side Cover

    Found the side cover to be more than I anticipated. When I used for the first time I noticed an oder like one gets with a new car. Oder disappeared after to several useses. It gives me the opportunity to use the machine without the Humidity tank and the noise that comes with it. Love the Side Cover!!

    Works great and makes life easier

    This thing makes it a lot easier for travel without having to bring the water or buy water and other places. Also makes it easier for when you’re camping and might not have an entirely flat surface.
