10 Best Dehumidifiers Reviewed & Rated in 2024

last updated Sep 09, 2019

Humidity isn’t just uncomfortable--left unchecked, it can create health hazards. Bacteria grows in areas that are moist and warm. If you want to keep your house clear of mould and dust mites, consider a dehumidifier. These powerful little machines remove moisture from the air by drawing air out over cold coils (which helps the machine to collect the moisture via condensation) and then passes the air back into the room through warm coils. We have ten of the market’s best for you to peruse below.

Price Range

High powered and pulls the moisture right off the air. This machine is great for a whole-house dehumidifier and works well helping to prevent mold and mildew throughout.

Criteria Used for Evaluation

Design

These dehumidifiers are the best-rated and the most-reviewed items of this category. Customers overwhelmingly loved the ones on this list the most and would purchase them again because of the high satisfaction they experienced. We read through the product descriptions, reviews, feedback, and online comments to bring you the most informative buying guides for your enjoyable shopping experience. We help you make an intelligent decision as to which of these products is the best for your needs and space requirements.

Ease of Use

The larger products have a continuous drain setup that you can implement or use the large water bucket that must be emptied often. The smaller units do not have the drain option and must be emptied as often as needed according to the moisture trapped from the room air. The water containers are easy to put in and take out, with at least one of them having to be snapped back in for security purposes to lock it in.

Portability

One dehumidifier isn’t going to cover the whole house. If you intend to move these machines between rooms or take it with you to other locations, you’re not going to want something that causes back problems every time you try to pick it up. Some of these units have wheels on them, making them far easier to transport between spaces. Stairs might still present a problem but even then, they’ll be easier to roll down rather than carrying. Opt for something lightweight if you think you’ll need to move it a ton and between different stories/buildings. Most models also include handles which allow you a sturdy grip on an otherwise bulky and difficult-to-move machine. If you’re worried about moving these units around, you can also opt to buy more than one. Just consult the square footage of the rooms you’re looking to dehumidify so you know how much power you’ll need.

Price Range

The dehumidifiers on our list cover a pretty broad price range. Sometimes you need something to bring a quick fix to a temporary problem. If you’re not interested in investing in a dehumidifier for the long haul and you just want something small to clear up a bedroom or small desk/office space, we made sure to include some more cost-effective machines. If you need something more permanent or stationary to cover larger areas and more square footage, we also made sure to list some heftier machines. When looking at price range, consider that the following criteria will likely affect the price: size (and square footage covered), portability, water tank size, and technological upgrades.

Did You Know?

All dehumidifiers take the bacteria-loving moisture from the air to make it healthy for people to breathe. Moist air holds harmful substances such as molds, mildews, bacteria that are terrible to breathe in.

Did You Know?

These devices can be placed in rooms that are known to be drafty and damp, such as basements, cellars, bathrooms, and closets. For those with asthma, dehumidifiers are almost a necessity in most rooms of the house for good health.

Frequently Asked Questions

q: Where should I put a dehumidifier in my home?

a:

Anyplace you feel you have moisture in the air in your home is a great place to put one of these. Good places are bathrooms, bedrooms, basements, cellars, closets, and even living rooms. Choose the proper size unit for the right side of the room. If the room is large, make sure the device can handle the large size. Smaller rooms only require a small machine to keep the air in check.

q: Do you have to have asthma to benefit from one of these?

a:

No, you do not have to have asthma or any breathing problems to enjoy and benefit from the clean dry air that these devices emit in the room. Everyone needs great air quality that these products can provide.

q: Exactly how does one of these devices work?

a:

Dehumidifiers remove the moisture from the room air that contains harmful bacteria, mold, and mildew particles. Placed in a room of the proper size for the moisture capacity of the unit, it will take out the moisture in the air you breathe. It takes in the wet air, removes the moisture, and puts out dry germ-free air in the room.

q: What are the benefits of having one in the home?

a:

Even if you do not have breathing problems, everyone can benefit from having drier air to breathe. The moisture in the air holds and breeds bacteria, mildew, and mold that we breathe in when we have moist air in a room. A dehumidifier removes the moisture and therefore takes out the harmful substances that live in this moisture. It makes for healthier air to breathe for everyone in range of the device.

q: How do you get the water out or does the machine just evaporate it?

a:

No, the dehumidifiers do not evaporate the water absorbed from the room air. It collects in a bucket in the machine or for the larger products, a continuous drain can be assembled with a garden hose. It is threaded through a drain in the floor or wall to go outside. The smaller devices must be emptied periodically depending on how much moisture is collected and how often.

q: Do these all run on electricity or do some of them take batteries for operation?

a:

All of these dehumidifiers run on electricity for operation, except the Eva-Dry product. That device is a tiny renewable dehumidifier that absorbs moisture with silica gel beads. One the beads are full of moisture, you plug in the device to dry out the beads. This is the renewing part of the process. It does not have to be plugged in to work though.
