There’s no denying that a good night’s sleep prepares you both physically and mentally for the day ahead. But if there’s too much humidity in your bedroom, this can negatively impact your slumber. Feeling hot and sweaty during the night often leads to sleep disruptions and if you suffer from asthma, too much moisture in the air may make breathing difficult.
Not only will your sleep be affected, but all that excess moisture can also lead to mold which may trigger any allergies and will ruin your walls. Purchasing a dehumidifier is an excellent way of helping you get a good, peaceful night’s sleep, and save you costly maintenance work.
When picking out our top bedroom dehumidifiers, we considered things like:
- Tank size
- Weight
- Price
- Special features
Room size is also an important factor when choosing your dehumidifier. Purchasing the right unit for your bedroom size will make all the difference. For example, the Pro Breeze Electric Dehumidifier is great for small bedrooms and covers 215 square feet. But if you’d like to find something to use in a bigger room, the Honeywell TP50WK is ideal and is suitable for bedrooms up to 3,000 square feet.
If you also want to keep your air clean at night, check out what we think is the best air purifier for a small bedroom.

FAQs about Dehumidifiers
Can you use a dehumidifier while sleeping?
Most definitely. In fact, having a dehumidifier running while you are sleeping is a good idea if the humidity levels in your bedroom are high. High humidity can affect the way you sleep in three different ways. Comfort, breathing, and allergies can all be affected by high humidity.
Let’s look at each one in turn:
Comfort. High humidity makes it difficult for moisture on the body to evaporate, leaving you hot and sweaty.
Breathing. In humid conditions, some people have difficulty breathing, especially asthma or other respiratory problem sufferers.
Allergies. If you have allergies, then high humidity can make mildew and mold easier to grow, triggering your allergies.
Why should you choose a dehumidifier over other traditional ways?
Choosing a dehumidifier over other traditional methods of removing excess moisture from a room makes sense if you think about it. You could leave all your bedroom windows open, but if the humidity outside is higher than the room, that option won’t work. Plus, you’ll get all sorts of bugs coming in. Alternatively, put a few electric fans all-round the room to circulate the air, then wait for the next electric bill to arrive. Or, you can have a dehumidifier in the bedroom, running quietly and efficiently removing the moisture from your bedroom and keeping the humidity at a comfortable level.
Where should a dehumidifier be placed in a bedroom?
Position the unit as close to the center of the room as you can, to start with. It needs a good flow of air to do its job, so keep it away from any possible obstruction like drapes, but in a position where you can keep an eye on the water tank level, in case it needs emptying.
Which Dehumidifier is Best for You?
Choosing the best dehumidifier depends on several factors, such as:
What are the humidity levels of your room?
What size of unit will best suit the bedroom?
Do you want to run it when you’re sleeping?
Does the unit drain automatically?
These and other questions should be considered before you make a choice.
For example, if you need to reduce the humidity level from 80% down to 40%, then you need to look at a dehumidifier’s specifications on how many pints per 24 hours it can extract for certain square footage.
The size of the unit is also crucial. If you choose a unit that has a small tank size (3 pints), then it will need emptying more often than a unit with a large tank (30 pints).
If it is going to run while you are asleep, then the noise level should be as low as possible so as not to disturb you. Look for a dB level below 40, which is about the noise a refrigerator makes.
So what’s the bottom line? Select a dehumidifier that can reduce the humidity to your comfort level as quickly and efficiently as possible, is most appropriate for your size room, and best matches your budget.
