For your morning brew: Use distilled water if you hate descaling. Otherwise, regular filtered water adds subtle flavor minerals that coffee snobs swear by.
For your plants: Distilled water is a godsend for finicky peace lilies and carnivorous plants that hate tap chemicals. Your fern will throw a tiny leaf parade.
For your body: Stick with drinking water for daily hydration. Add a pinch of sea salt to distilled if you’re experimenting with pure water—it mimics the electrolyte profile your cells crave.
Fun fact: The World Health Organization actually cautions against long-term use of demineralized water for drinking. Even the pros want a little mineral kick in their glass.
