Running a humidifier costs pennies a night. But buying distilled water adds up. If you use a gallon every two days, that’s $15 to $30 a month. That’s a streaming subscription, plus a nice takeout meal.
Compare that to the cost of replacing a humidifier every year due to mineral scale—which can run $50 to $200. Sometimes the distilled water is cheaper in the long run. It’s like paying for oil changes to avoid a new engine.
Fun fact: distilled water is also used in car batteries and steam irons. You’re basically giving your humidifier the same VIP treatment. Look at you, being fancy.
