Can you try distilled from some other source for a week and see if there's a difference?Elle wrote:I clean my humidifier at least once a week and should probably do it more often because there is a film of white on the bottom when I empty it. I run my finger across the bottom and can see a line. I guess I should do it more often if I want to eliminate that but I hate to waste the water. I get distilled at London Drugs.
You might also want to check and see if the actual source of the water is listed on the label. The stuff I get at Walmart is labeled "produced by Premium Water, Dallas TX. " or some such.
