Welcome to the board. If you don't have any access to distilled water don't sweat it if all you are using it for is to hydrate the water pillows. Just use bottled water. The problem with using non-distilled water comes when you use it for the humidity beads or the florist foam in traditional humidifiers. I think bottled water will be ok in your case. What are you keeping the cigars in? Humidor or tupperware.
