Does a Cool Mist Humidifier Make the Room Cold?

The name “cool mist” may make you think that the mist is capable of cooling down your room.

Unfortunately, the “cool” mist only describes how the humidifier operates. Warm mist humidifiers rely on a heating element and boiling water while cool mist humidifiers use ultrasonic vibrations to disperse steam around your room.

Below you’ll find out more about cool and warm mist humidifiers.

Let’s get started.

Does a Cool Mist Humidifier Cool the Room?

A cool-mist humidifier will not cool the room. The opposite is true, where the higher the humidity in your room, the warmer you may feel.

The “cool” in “cool mist” refers to how the humidifier operates rather than the temperature of the mist.

Warm mist humidifiers rely on boiling water to humidify while cool mist humidifiers use ultrasonic vibrations to disperse water around your room.

Does a Warm Mist Humidifier Heat a Room?

Unlike cool mist humidifiers, warm mist humidifiers rely on a heating element to boil water to create steam.

Warm mist humidifiers can make a room slightly warmer, but you may feel warmer regardless due to the humidity level increase in your room.

Warm mist humidifiers can be dangerous if left around with pets or children, so keep them out of reach or use a cool mist humidifier.

Can a Cool Mist Humidifier be Dangerous?

A cool-mist humidifier is much safer than a warm mist humidifier as it doesn’t rely on boiling water or heat to generate steam.

You may think that a warm mist humidifier may be better for dry skin, hair, or illness as the mist is “warmer”, but by the time steam disperses into the air the temperature difference is negligible.

Any humidifier can be dangerous if it isn’t cleaned properly, you leave it on too long or you don’t use distilled water.

If you leave your humidifier on past the recommended 50% humidity level, you put yourself at risk of heat exhaustion, muscle cramps, fatigue, and dehydration.

If you’re going to use a humidifier, ensure you have a way to measure the humidity levels or use a humidifier that turns itself off once it reaches your desired humidity level.

Best Way To Monitor Humidity Levels

The most reliable way to ensure you don’t encounter any issues with using your humidifier is by ensuring the humidity levels don’t go past 50%.

The best way to monitor your humidity levels in your room is by using a hygrometer. Hygrometers are a cheap device that can help prevent the side effects of high humidity.

So, Cool or Warm Mist Humidifier?

Cool mist humidifiers should be used by anyone with pets, children, or who are worried about fire hazards from the heating element.

Warm mist humidifiers do operate a bit quieter, but the difference is negligible.

Warm mist humidifiers can also heat your room a tiny bit, while cool mist humidifiers will only increase the humidity level without any heat involved.

For most people, cool mist humidifiers will be the best option.

Final Thoughts

A cool-mist humidifier will not cool down your room, in fact, it may even make it feel warmer due to the humidity.

A warm mist humidifier will however be able to “warm” up your room ever so slightly, but don’t count on it as a heat source.

For most people, a cool-mist humidifier is going to be the safer option as it doesn’t rely on any heating elements.

If you’re wanting to heat your room, then go with a warm mist humidifier but don’t expect it to work as well as indoor heating.
