The gold standard for humidifiers is distilled water. This is water that’s been boiled into steam, then condensed back into liquid. All the minerals are left behind, making it as pure as a monk’s thoughts. Your humidifier will love you for it. No white dust, no bacterial raves, no weird smells.
But here’s the shocker: distilled water is basically dead. It lacks the minerals that give tap water its taste. If you drank it, you’d think, “Wow, this is what void tastes like.” That’s fine for your lungs, though—your lungs don’t care about flavor. They just want clean, invisible wetness.
Cost? Expect to pay about $1 to $1.50 per gallon at the store. For a large humidifier running all night in a dry room, you might burn through a gallon every 12 hours. That adds up faster than your coffee budget. Pro tip: if you’re a cheapskate (like me), you can distill your own water at home with a countertop distiller. It’s a $100 gadget that pays for itself in three months of winter, and it makes you feel like a mad scientist.
