The approach of dry winter weather inevitably leads to one problem: what type of humidifier to buy. While there are many types and models, most are either the warm mist type or the cool mist type. Although they work in similar manners, their differences can be critical.
Warm mist humidifiers operate by electricity heating a metal wick, which heats water and slowly releases moistening steam. This heating can be helpful because it will destroy many microorganisms and other impurities, creating more sanitary, healthful air. Also, warm mist humidifiers are often equipped to operate with medical inhalants, which can treat conditions like coughs. The biggest downside is that they can be too hot and cause burns, which can be a cause of concern for anyone with young children or overly curious pets.
Cool mist humidifiers release moisture into the air by mechanisms called a rotating disc and a diffuser. While this type of humidifier is just fine at moistening air, it doesn’t have the sanitary benefits that heat provides. On the plus side, they tend to use less electricity than warm mist humidifiers and there is no risk of burns.
It’s critical to clean both warm mist and cool mist humidifiers frequently. Check the humidifier’s manual for detailed instructions.
Taking this all into account, the bottom line is that most people are best off with a warm mist humidifier, since in creates safer air. The exception is people who are worried about burns, which can be a legitimate concern, especially if their household contains kids.
