Tap water in most developed countries contains trace levels of chlorine and is safe to drink. But standing room-temperature water for days is a microbial party invitation. Bacteria and mold love a dark, wet tank, and tap water introduces a few gatecrashers that distilled water wouldn’t.
The Environmental Protection Agency (EPA) has actually stated that tap water is not recommended for use in humidifiers, specifically citing the risk of dispersing microorganisms. This is less about the water source itself and more about the breeding ground you create. Daily cleaning becomes non-negotiable if you’re using tap, unless you want to turn your bedroom into a petri dish.
Culture-wise, consider Japan’s obsession with humidity solutions. Many Japanese homes use advanced humidifiers with silver-ion cartridges specifically to combat tap water issues. It’s a reminder that sometimes the best tech is designed around your water’s personality.
