I have been using my SoClean for a few years now, and it seems to have helped with the morning headaches I used to get before using it. Recently, though, the seal on the water chamber started making a noise, and it became tricky to get a good seal to stop the noise. So, I figured it was time to get a new CPAP machine. When Baycare Homecare delivered the new machine, they suggested not using the SoClean because it could cause the internal seals to wear out quicker than they should. Now, I'm not sure whether to keep using the device since it seemed to work well for me before. I think I will give it a try without the SoClean for a bit and see how it go's.
