In 2026, scientists tested 28 brands of bottled water and found microplastics in 93% of them—including “premium” purified water. Distilled water is the rare exception because the vaporization process leaves plastic particles behind. So if you ever want to drink water that’s certifiably plastic-free, you have to boil it like a witch’s brew. You’re welcome, environmental anxiety.
When to Use Which (So You Don’t Look Like a Fool)
Use distilled water for things that hate scale: CPAP machines, humidifiers, steam irons, and car batteries. Never use it for your houseplant’s coffee—plants need minerals, and distilled water makes them sulk like a teenager denied Wi-Fi.
Use purified water for drinking, cooking, and making ice cubes that don’t taste like your fridge’s leftover fish. It’s the water you’d serve a guest without apologizing. Just don’t refill that plastic bottle 50 times—unless you want to become a microplastic connoisseur.
