Now, what about your plants? This is where things get spicy. Some plant parents swear by distilled water, because it’s free of chlorine and fluoride that can turn leaves brown. If you have picky plants like orchids or ferns, they’ll thrive on the stuff.
But here’s the twist: most houseplants actually need the minerals in tap water to grow strong. Giving them distilled water is like feeding them a diet of only white bread—it’ll keep them alive, but they won’t exactly be flexing their green muscles. So, use it sparingly, or alternate with tap water. Your spider plant won’t judge you either way.

If you have a fish tank, distilled water is a must—but only if you add special minerals back in. Fish are dramatic, and they’ll die if the pH swings too much. So, don’t just pour a jug of distilled water into your goldfish bowl unless you want a very sad, floating goldfish.
For baby formula, some parents use distilled water because it’s sterile and free of impurities. The American Academy of Pediatrics says tap water is usually fine, but if you want to be extra cautious (and you have a spare jug lying around), go for it. Your baby won’t complain—they can’t talk yet.
And for your pets? A bowl of distilled water is fine as an occasional treat, but don’t replace their regular water. They need the minerals for their bones and teeth. Plus, if you have a cat, it will judge you regardless of what you serve.
