If you own a Costco membership, you are a god among humidifier owners. They sell distilled water in massive, apocalyptic-sized jugs that could survive a zombie outbreak. You’ll feel like a water dragon hauling them to your cart. The price per gallon drops to pennies compared to the supermarket, but you’ll need a second car just for the jugs. Warning: Your trunk will smell vaguely of plastic for three weeks. Worth it.
And no, you cannot just boil your own tap water. That’s just sterile tap water, not distilled. You need a countertop distiller—which costs $100 and makes your kitchen look like a science lab. Only do this if you enjoy explaining your “hobby” to confused dinner guests.
