Can You Put Regular Water in a Humidifier
You can put regular water in a humidifier, and the world won’t end. Your sinuses will still get relief, and your plants will still look happier. But if you want your machine to last longer and your furniture to stay dust-free, give it the good stuff—distilled or filtered water.
Think of it like this: you wouldn’t put soda in your car’s gas tank, even if it ran. Your humidifier is the same—it needs clean, simple fuel to do its job. Your nose will thank you, and your coffee table will, too.
