DreamStation Water Tank

I have read all these reviews and the first thing I noticed, those who gave a low rating do not know your chamber. I have been on a CPAP for 12 years and I know how much water to place into the chamber even with my eyes closed. Com'on man.I always order my replacement chambers from this site and have never had any issues on how to fill the chamber,

I have had this tank for many years now. I used to set it at 3, but moved down to 1. I have not had a problem with the humidity at 1, or the tank running out of water. In fact, I get multiple nights out of a full tank.

I haven't had the same experience with the water running out and I have a 4 setting for humidity and typically sleep 5-7 hours.

got a suggestion take a black magic marker and draw a line over the lines. I fill mine in the machine everyday with no problem, hope it works you all

I agree with others about hard to see filling line, plus it doesnt hold enough water when using the 5 level to get through the night during winter. This is the only one I have used so dont know if there is a better machin out there, havent used for a year yet.
