A humidifier can do wonders for your health and indoor air quality. But if you don't clean it regularly (we're talking at least once a week, depending on how often you use it), then it might be doing more damage than good. As with any appliance that involves water, it can be a breeding ground for harmful bacteria and mold. To ensure you clean your humidifier correctly, we've laid out every step you need to follow below. The best part? You don't even need that many materials to do it.
