Using more water in my humidifier
#1
Using more water in my humidifier
Not sure as to why, but the last few weeks, my humidifier has been almost dry / dry in the morning. I fill it up to the MAX line, and in the morning, I have to use white vinegar to get rid of the mineral deposits left in it. 

It's now been over 10 months since having started SA therapy. This hasn't been a big issue in the past. I could count on a couple of fingers the amount of times the water reservoir went dry. Now, it's happening quite often. 

Nothing has changed in regards to how long I'm sleeping, and I haven't messed any with the humidifier settings. I have the Climate Control on auto. My heated hose is turned off. Since I don't have any rainout issues, it's always off. 

The only thing that I can think of, is the humidity level is low where we live, right at about 12%. I've seen others post about the same issue and asking about reservoirs with more capacity. 

Anyone have any thoughts, suggestions, or ideas?  Dont-know

RE: Using more water in my humidifier
as you suspect: lower summer ambient humidity = higher usage. insufficient chamber capacity for your environment? try a manually set lower humidification setting to make it last the night.

I was thinking along those lines and will do just that.  Thanks

RE: Using more water in my humidifier
This is most likely, that humidity levels have lessened and the water surface lets more molecules up into the air passing over it.  Or, it could be a small leak, but you'd think you'd spot staining near the machine.

If you can sleep comfortably with lower settings, that may help.

I think it's a fairly substantial change, though, and wonder if something else isn't afoot.

I can say for sure, nothing is leaking. It can get quite dry here in AZ. Humidity level is for the most part, usually very low. 

But, our monsoon season is due at any time. We can and do get very heavy rain storms. I dropped my humidity level down to a 2 on my machine. I'll see if that happens to help any.

Certainly. The CPAP machine will actually measure the ambient humidity and adjust the temperature of the water in the reservoir accordingly. So when the ambient humidity falls, the water is heated more, so more of it will evaporate.

The solution, as has already been stated in this thread, is to turn down the heat.

Another solution would be to humidify the bedroom. One of those cheapies they sell at Walgreens would do the trick. The problem, though, is that if your water is hard enough to leave mineral deposits in the chamber, it is probably too hard to use in a vaporizer.

Not a big fan of humidity. Wasn't sure how I would respond to a humidifier in a CPAP machine. I was surprised that I've done as well as I have. 

Our water here is on the hard side of the spectrum. I think for the time being though, I will decrease the humidity level as needed in my machine and see how that goes.

Sure is hard. I use water from our reverse osmosis system in the kitchen, and it works fine and does not leave any deposits in the machine.

12% humidity?  That's almost high for Arizona!  We're at 6% right now here in Tucson.   Laugh-a-lot

RE: Using more water in my humidifier
Yeah at least it’s a dry heat they say. At 6-12% humidity I’m wondering if I’d turn into human beef jerky or something...
