Cool vs Warm Mist Humidifiers

Having a humidifier ready at home is crucial, especially when the winter season approaches. Especially in winter, but this can also happen in any other season if the temperature reaches extremes, the air can become very dry because there is not enough water vapor in it. Such condition is detrimental – your skin, nose, and throat suddenly feel so dry, your plants get super thirsty, and even your hardwood floors may be damaged.

There are various shapes and sizes of humidifiers out there, but you can easily classify them into cool mist humidifiers and warm mist humidifiers. What are the differences? Which is the type best for you?

Cool Mist Humidifiers

As the name suggests, a cool mist humidifier works by emitting a visible plume of cool water vapor into the air. It kills and removes impurities from the water by using filters. Cool mist humidifiers tend to be silent when working, allowing you to focus on your activity and sleep well. Cool mist humidifiers are recommended to help to relieve congestion and coughs.

Warm Mist Humidifiers

On the other hand, warm mist humidifiers emit warm, heated water vapor into the air. A warm mist humidifier utilizes heating elements to warm the water, killing most bacteria before the water vapor is released. The warm mist can be soothing during a cold day. However, some warm mist humidifiers may produce a humming sound when working. They can also get very, very hot. The vapor may burn if you get too close to the device, and, in the case of a spill, the hot water can burn as well.


In general, especially for children, cool mist humidifiers are better, as they are more quiet and safer. Meanwhile, warm mist humidifiers can be your choice if you need some extra warmth for the room.
