If you live in a humid environment and have trouble sleeping at night because of it, a simple way to improve your air quality is to use the best dehumidifier for bedroom. There are so many benefits to getting such a machine. Because it removes moisture from the air, it helps lower the risk of mold and mildew growth, reduce odors, and can help your air conditioner work more efficiently which can save you money as well.
For our review, we considered some of the most crucial factors when you’re looking for the best dehumidifier for bedroom. First, the sound level is significant because you don’t want a machine that makes so much noise, you just won’t be able to sleep because of it. Next, we looked at dehumidification performance because it’s important to know how much water the unit is actually able to remove. Coverage area is also important because each model is designed to work in a certain size room. If the room is too big for your dehumidifier or vice versa, the device won’t work effectively. Finally, we considered dimensions. Most of our picks are designed to sit on your dress or nightstand and it’s important to choose one that’s right for your space.
To put together this guide, we spent hours researching reviews, comments, and the specs of each product. First, there’s a table where you can see our picks for the best dehumidifier for bedroom compared side by side. After that are out detailed reviews followed by a handy buying guide to answer any questions you might have.
The Afloia 2000ml Dehumidifier for Home is a large capacity option that holds up to 68 ounces of water. At 86 degrees Fahrenheit with 80% relative humidity, this machine can pull up to 26 ounces of water out of the air every day.
It’s a great option if you’re looking for the best quiet dehumidifier for upstairs bedroom. The dehumidifier produces about 42dB when it’s running which is a really low level of ambient noise meaning it won’t disrupt your sleep. This is a mid-size design that’s somewhat portable. It doesn’t take up too much space and weighs less than six pounds and is perfect for bedrooms as well as bathrooms or small offices.
Another great thing about this machine is that it’s effortless to use. All you have to do is plug in the AC adapter and turn it on. It turns off automatically when the reservoir is full and notifies you with a simple LED light. The reservoir is easy to remove for emptying and cleaning. It’s eco-friendly, too. Thanks to the low energy consumption, it doesn’t waste electricity.
This machine has set parameters for use. The manufacturer recommends that the relative humidity is at 60% or higher and the temperature should be at least 68 degrees Fahrenheit to get the best results. So make sure you stick to these requirements, and the dehumidifier will serve you well for many years to come.

The Eva-dry Edv-1100 Electric Petite Dehumidifier is our pick for the best small dehumidifier for bedroom. It’s one of the most compact, lightweight options on the market. It’s easy to use, has low energy consumption, and uses a brushless motor rather than a compressor which doesn’t make nearly as much noise. In fact, one of the best features of this model is that it is one of the quietest dehumidifiers on the market.
This dehumidifier weighs only one pound and is easy to move around. It’s made using durable high-quality materials and is a perfect dehumidifier for a bathroom or small to midsized bedroom up to 1,100 cubic feet. It can even work as a dehumidifier for your garage if it’s not too spacious.
It’s really easy to use, too. Just plug it in and turn it on. The reservoir holds sixteen ounces of water and gets full after about 24 hours of operation. When this happens, the machine turns off automatically. Then, you just have to remove the spill-proof reservoir, dispose of the water, put it back, and the device is ready to get to work again. One downside is that it needs to be pretty warm for this machine to perform well enough to collect eight ounces in 24 hours. In fact, the specifications for the unit are for a temperature of 86 degrees Fahrenheit. If you’re not going to be using it in an area that’s quite that warm, you may not get the same results.
The best budget dehumidifier for bedroom is the KEDSUM Electric Mini Dehumidifier. It’s compact but still has a decent reservoir capacity of 17.6 ounces. It’s a small, quiet machine that’s ideal for small spaces of up to 150 square feet or 1200 cubic feet.
This portable Peltier humidifier weighs only 2.25 pounds and is easy to transport from room to room. The small, compact size doesn’t take up too much space. It’s a perfect size for a bedside table, desk, or dresser and features anti-skid feet to keep it right where you need it.
The water reservoir can hold up to 17.6 ounces, and this machine can remove up to 8.8 ounces of water a day in the right environment. The tank is easy to remove, empty, and clean, and the machine automatically shuts off when it’s full alerting you with a simple LED light.
Buyers commented that, while this machine worked well, it was much better when used in very small spaces (works great as an RV dehumidifier, by the way). So if your bedroom is somewhat large, this may not be the perfect option for you.
The Vacplus 30 Pints Dehumidifier uses a compressor for increased power and can remove up to 30 pints of water from the air every day based on a room temperature of 86 degrees Fahrenheit with 80% relative humidity. The large water tank holds up to 46 ounces at a time, and machine turns off automatically when full to avoid spillage. The reservoir is also easy to remove and clean.
Although this is a powerful unit, it still operates relatively quietly and won’t disturb you while you sleep or relax in bed. It’s a bit larger than some of the other items on our list and is designed to sit on the floor, though there are wheels on the base for easy transportation from room to room.
One downside, as you may have noticed, is that it’s designed to collect much more water in a day than it can actually hold. That means if you live in a warm, humid climate, you may have to empty the reservoir several times a day. There is a hose included so that you can set up a continuous drainage system where the water runs into a larger bucket or even outside.
It comes with a two-year warranty and lifelong service which should take care of any defects.
What we liked:
Can remove up to 30 pints of water from the air in 24 hours

Frequent emptying of the reservoir when working optimally
A unique thing about the Tenergy Sorbi 1000ml Air Dehumidifier is that it’s more than a dehumidifier. It’s also equipped with HEPA filter so that the air is cleaner and you can breathe easier. This small, quiet machine is excellent for bedrooms of up to 200 square feet and easy to move from room to room when you need it.
This machine has a reservoir capacity of 34 ounces which is almost how much it can remove in a 24-hour period in optimal conditions. When the reservoir is full, the machine automatically shuts off and alerts you using an LED light. It’s also a great size if you’re looking for something portable and weighs only seven pounds so it’s easy to take from room to room.
What’s great about this product is the HEPA filter which helps trap micro particles and can reduce allergens in the air, like pollen, dust, or pet dander. It’s a good choice for anyone suffering from allergies, especially if you tend to have problems overnight. The HEPA filter should be replaced every six months though some users have mentioned that finding replacement filters can be difficult.
Users didn’t have that many complaints about this model except to say that it can be loud when running on high. However, the manufacturer stated that the maximum noise level is approximately 42dB which is quieter than a normal conversation. If it’s a concern for you, set the unit at the lowest setting when you leave it working overnight.

Relatively loud on high setting
Things to Consider
When it comes to choosing the right dehumidifier, there are a lot of things to keep in mind if you want to find the one that will work most effectively in your space. Let’s take a look at some of the things you should consider.
Features to consider while choosing a dehumidifier for bedroom
The last thing you want is a dehumidifier that is so loud, you can’t sleep. Pay close attention to the decibel level. Some of these machines, like the Afloia 2000ml Dehumidifier for Home, are pretty quiet. They only have one-speed setting so you can pretty reliably determine how loud they’re going to be by looking at the number of decibels.
There are dehumidifiers out there that have multiple settings, like the Tenergy Sorbi 1000ml Air Dehumidifier. In this case, the high-speed setting is bound to be louder than a low-speed one, which completely makes sense.
Just be sure you look into how much noise is produced on both the high and low settings so you’re not surprised.
This is one of the most important things to consider if you want your dehumidifier to operate most effectively. Each model can handle a certain amount of square footage. For example, the Vacplus 30 Pints Dehumidifier covers 200 square feet.
If you take a dehumidifier that’s meant for a room of 200 square feet and put it in a 300-square foot room, it’s never going to be able to keep up. It’s just not designed to move the amount of air that it would have to in order to work properly in a room that large.
Some users had a lot of complaints that their machines weren’t working as promised or were barely pulling any water out of the air. Reports like this beg the question of whether or not they were being used in a room that was too large for them to handle.
This is a wonderful feature that ensures you don’t have any accidents or leaks. Generally, how it works is there’s a sensor of some sort in the water reservoir. As it gets full, the sensor is set off and automatically shuts down the dehumidifier. Without this feature, the machine would just keep going which could potentially lead to overflow and a soggy wet mess to clean up. Thankfully, all the products listed boast this handy feature.
Water tank capacity
Tank capacity is how much water the machine can hold. Usually, this somewhat lines up with performance. For example, the Tenergy Sorbi 1000ml Air Dehumidifier can hold 34 ounces and removes 25 ounces every day.
Occasionally, you’ll come across a machine like the Vacplus 30 Pints Dehumidifier that removes a lot more water every day than the reservoir can hold. That means you’ll probably have to empty it a lot more frequently than other models, but there’s also an indicator that it’s working properly.
A lot of these machines are very simple to use and only have one mode. You just plug them in, turn them on and walk away. That said, there are a few options out there with various modes and speeds to choose from. You’ll have to determine whether or not you want the option of different speeds. The Tenergy Sorbi 1000ml Air Dehumidifier, for instance, has two speeds to choose from.
Dimensions and weight
Dimensions and weight are most important when you’re considering a portable dehumidifier. If you plan on taking it from room to room or floor to floor, something small and lightweight is best. The Eva-dry Edv-1100 Electric Petite Dehumidifier is compact and lightweight enough to store on your nightstand, for instance.
If you’re looking for something that will stay exclusively in the bedroom, you don’t really have to worry about portability, but you still need to make sure you have the space to set it up on a dresser, nightstand, or desk. Most tabletop models are pretty compact, but there are a few different sizes available so check the dimensions before you buy.
Warranties are always important. Unfortunately, they’re not always very straightforward. If your humidifier comes with a warranty, make sure you read it carefully, so you know what’s covered and, more importantly, what isn’t.
There are some design features that aren’t essential but can make things a little more convenient for you.
Some dehumidifiers have LED lights that let you know when the reservoir is full and needs emptying. This is a handy feature because you just look over and see if the machine is still running or if it needs emptying before it can get back to work.
When it comes to portability, some of these machines have several nice features. Look for carrying handles to help lift the device into place or rubberized feet to prevent them from slipping on the tablet surface. If you have a large floor model, wheels will come in handy when it’s time to move it to another room.
Tips to reduce excess humidity in your bedroom
There are some things you can try to reduce humidity in your bedroom naturally.
Open windows and doors and use fans to circulate the air around the room. The fans will also help excess moisture evaporate more quickly.
Turn on the air conditioning. While the primary job of an air conditioner is to bring down the temperature, it’s also an easy way to lower the humidity in a room. Be sure to change filters regularly to keep it running as efficiently as possible.
If you have a bathroom attached to your bedroom, taking shorter, cooler showers can help. The longer and hotter the shower, the more the humidity increases. When you open the door, it quickly makes its way into the bedroom. Another way to help alleviate this is to use the extraction fan in the bathroom while you shower.
Don’t keep plants in the bedroom. Household plants can add moisture to the air. If you’re worried about reducing the humidity in your bedroom, it’s best to keep your indoor plants somewhere else.
If you’ve tried these interventions and still have problems with humidity, a dehumidifier is your best bet.
They can even keep it in a perfect condition! Some models have features that turn them off when the humidity in the room gets below a certain level. This prevents the air from getting too dry which can irritate sensitive skin. If you use a model with a HEPA filter, that can help, too. Since it removes a lot of allergens from the air, it may eliminate anything that can harm your skin.
Generally, yes, as long as you’re diligent about where you place it. If you have a home with children and pets, keep the humidifier in the back, middle of your dresser with the cord out of reach so that they don’t have access to it or just keep your bedroom door closed to discourage them from getting into the machine or knocking it over. Also, if you have a child with asthma or allergies, a dehumidifier can actually help them breathe easy while they sleep by improving the air quality.
