Using and type of water in the humidifier

[JeffL]

I've previously posted that I only use distilled water because when I tried tap water, it left a dusty, mineral stench in my nostrils when I woke up. It was the same smell I got when I had used tap water in an ultrasonic humidifier (which also created a white dust from the nebulized minerals in the water). I now have to say that your mileage will vary depending on you local water supply. Last week I had to make an overnight trip to Ft. Myers, FL, and didn't have the time, or desire to buy a gallon of distilled water. I used the tap water in the hotel for that one night, and didn't notice any difference over the distilled water I use in Los Angeles.
BTW, just got back from Smart and Final, where I bought two 2.5 gallon bottles of Sparkletts distilled water for $2.04 each. I had been getting the 1 gallon bottles for $.99 each (up 10 cents over last year), but they were out. They have the lowest prices I've seen around here.

After reading these posts I think I am goofing When I got my CPAP the DME told me to use "bottled water". So I do. However it is the water you buy by the case in Walmart. I recently bought 2 one-liter bottles at Dollar General for 65 cents each but it says Natural Spring Water. Is this the same as distilled?

No.
It has to say "DIstilled"
Otherwise, minerals in the water that may make it taste good will crud up your tank.
