Any H20 is just fine. Tap water works just as well with exception that it carries some minerals or flourides. (Certainly not enough to cause any concern)
I am not sure where you got your information ifrom but I completely disagree. As Jai_Jai_Binks said there is absolutely no reason to use bottled water. First of all, bottled water and distilled water are different. Bottled water can be glorified tap water, purified water, or spring water - all of which contain minerals.
Second of all, the minerals are of concern. Sure, in a closed system where the water never boils off it wouldn't be an issue, but if the water wasn't boiling off/leaking, you would never have to refill it.
Do yourself a favor and get distilled water
