I have a lot of animals and am co stantly scrubbing and disinfecting water dishes and bottles.It’s not the bacteria in the water, it’s the bacteria in the air that eventually comes in contact with the water.
Adding this the humidifier to the pile won't be a problem.
Do I need to use distilled water or will britta filtered water do?
Its what I currently use for misting as well as in my glass tea kettle(i had hard water deposits) I'm on a well. The water is safe for drinking.
