White Film in Humidifier Tank

I guess that I had better use bourbon. It is distilled after all.

Actually, it has never run dry. I allowed it to dry at room temperature after cleaning it and the tank has only been used since 8/13/2014. I thought it was kind of interesting. I do not remember the tank in my S8 developing this film.

Could be the metal they are using for the tanks these days is more prone to oxidation. If it is damp (i.e. from washing) and you let it air dry (like we're supposed to), it can have the exact same effect.

PsychoMike, all winter long my tank ran dry during the night, I was never able to learn how long it was dry. Minnesota winters are cold and dry, and I've noticed my summer humidifier use barely puts a dent in the water supply. Is there anything to do for the winter to keep it from running dry?

I started cpap on Feb. 3 this year, and my humidifier didn't show a film until July or August. I picked up another at that time. I do rinse the tank every night, wash it once a week or so with other supplies.

Depends on what you're comfortable with, the mask you use and what your settings are. My winters in Alberta can be cold and dry too, so I noticed a change in water use when using an automatic setting too. Since going to manual control of my humidity, I've found a setting that works well with my current mask and doesn't leave me or the humidifier dry in the morning....plus I can boost things when I need to (like when I have a cold )

Try a product called Lemi-Shine to remove the residue from your humidifier tank. Just sprinkle it in the tank and then add hot water, let it sit for a few minutes and rinse. It works wonders and you don't have to scrub. Product is available online or at Wal-Mart.
