If you’ve been reading about dehumidifiers, then you may know that they’re used for reducing the humidity in a room. But do dehumidifiers cool rooms?

Whether you’re using a dehumidifier in your bathroom only or you’re trying to reduce the humidity in other parts of your house (especially during summer), a dehumidifier is a great way to take the moisture out of the air and make a room feel more dry.

But does a dehumidifier cool a room? If humidity decreases, does this make the air in the room cooler? Read on to find out more.

Do dehumidifiers cool rooms?

do dehumidifiers cool rooms

The sole purpose of a dehumidifier is to reduce the humidity levels in a room, not to make the air cooler like an air conditioner does. So technically speaking, dehumidifiers do not cool rooms.

A dehumidifier sucks air into it and turns the moisture in the air into water droplets that are then emptied from the dehumidifier via a hose and pump or sit in a water tank until it is ready to be manually emptied.

Does humidity increase the temperature in a room?

Humidity itself doesn’t increase the temperature in a room but to a person, humidity makes them feel hotter.

If you ask a person to stand in two rooms at the same temperature but one has high humidity while the other doesn’t, the person will feel hotter in the high humidity room. This is because the humidity prevents the person’s body from being able to regulate body temperature via sweating, thus making the person feel hotter.

When a person’s body is hot, the body sweats to help cool down the person. But if there’s high humidity in the room, the sweat cannot evaporate from the skin, leaving the person feeling hot.

Humidity can also have indirect impacts on your health, as outlined in researched published by the U.S. National Library of Medicine.

So, does a dehumidifier cool a room?

If a person feels more hot in a humid room, does that mean that a dehumidifier, which reduces humidity, cools a room down too?

No, a dehumidifier does not cool a room’s temperature. Even though a person feels cooler in a room with lower humidity, the actual room temperature has not changed.

So while a dehumidifier takes the moisture out of the air and causes the humidity level to drop, the room temperature itself has not changed. A person will feel cooler because their body is able to regulate temperature through sweating, something which isn’t possible in a high humidity room.

Will a dehumidifier help cool a room?

A dehumidifier will remove humidity in a room which will help a person feel cooler, but the room temperature itself won’t change.

How to use a dehumidifier to cool a room

To stay comfortable during a hot, humid summer, you will need a dehumidifier to remove the moisture in the room which will help people feel cooler, but you will also need an air conditioner to cool the temperature in the room.

Using both an air conditioner and a dehumidifier will make your room feel cooler and more comfortable. Moisture can still be in the air even when the temperature is cool, so don’t be fooled into thinking a cold room can’t be humid!

Do I need a dehumidifier if I have air conditioning?

Humidity levels don’t change much when you’re using an air conditioner. A room can still be humid even when the room temperature has fallen. If your room is humid, even when using an air conditioner, we recommend using a dehumidifier too.

Do dehumidifiers cool rooms that have air conditioners?

An air conditioned room that also uses a dehumidifier will have lower humidity levels. By using a dehumidifier even in a room with air conditioning, the room will have less moisture, allowing a person’s body to regulate temperature through sweating. This will make the person feel cooler, although the overall room temperature won’t have changed- just the humidity level.

One final word

Do dehumidifiers cool rooms? In summary, no, dehumidifiers do not cool rooms. But they remove the moisture in the air which allows our body temperatures to self-regulate and make us feel cooler. High humidity prevents our sweat from evaporating which leads to feeling hotter even if the room temperature hasn’t changed.
