The Best Dehumidifiers To Improve Your Home's Air Quality & Your Health

If you have a damp bathroom or laundry room, this mini dehumidifier may be all you need. A smaller model, it comes in at a little over 12 inches high—but don’t be fooled, it works wonders in small spaces up to 250 square feet. This dehumidifier can even be used in RVs, trailers, and boats. 

This option removes up to 18 ounces of moisture per day and operates without a compressor, which keeps the machine incredibly quiet. An auto shut-off function prevents it from running overtime, and the simple-to-use water outlet makes for easy draining. Keep note that, like most dehumidifiers, it functions best in temperatures between 59 to 86 degrees Fahrenheit. 

With over 12,000 five-star Amazon ratings, this dehumidifier is a cult-favorite among customers who love how scaled-down and quiet it is. One reviewer shares, “Perfect for a small space (I use it in my kitchen on humid days to reduce moisture when preparing certain foods) and the noise level is not particularly noticeable. It works well—I've noticed the difference since I've started using it. Well-priced also compared to other options.”

Efficiency is the name of the game for this dehumidifier. Its real-time humidity display helps you keep track of moisture levels, with a full-bucket indicator that alerts you when the tank is full. This particular model has three options for drainage: manual drain, which involves removing the bucket yourself and pouring the water out; gravity drain, which utilizes gravity to drain water continuously via a hose; and an internal pump option that pushes water sideways or vertically up to 16 feet (using a line or tube) once the tank is almost full. This unique feature can be especially beneficial when trying to rid moisture from damp basements. 

As for safety precautions, this dehumidifier has overflow protection (no messes or leaks on the floor), is made from fireproof materials, and is UL-approved, meaning it meets the highest safety standards. What’s more, it also comes with a timer that allows you to schedule delayed start times in 2- to 4-hour increments. 

As expected, customers rave that this model vastly improves their living spaces. One reviewer notes, “This dehumidifier has worked wonderfully! Placed it in my basement which was damp and over 80% humidity, and in a week it had dried it out and had the humidity down to 50%. The pump is a must. I hooked it up to the washing machine drain and just left it to do its thing. The machine continues to maintain a comfortable humidity in the basement, and mold is no longer a problem.” 

However, some people do comment that this model is a bit loud and may be better suited for basements or garages, where the noise won't be a distraction.

One of the most versatile options, this dehumidifier can be used in its nested or expanded form, depending on room size or how much humidity you’d like to get rid of. To expand the device, simply lift and twist the top. The adjustable design is especially great for storage purposes.

What’s more, this dehumidifier can be controlled via the brand’s app. This allows you to monitor water and humidity levels even while you’re not home. The machine can collect up to 50 pints of moisture per day and has an auto restart function, which comes in handy if there are any power disruptions. A nifty auto-defrost function ensures that the tank's water doesn’t freeze in lower temperatures. 

Customers are pleased with this dehumidifier and love how quickly it sucks up stubborn moisture in large rooms, such as basements. One writes, “Our humidity in the basement is already down from 67% to 49%. It’s very quiet though in the basement it would not be an issue for us.” Another happy customer adds, “I am so happy with the quality of this product! We suffered a devastating flood in our basement after hurricane Ida, including losing our dehumidifier. At first this one ran constantly, which worried me but now it rarely comes on. I have it set to 40% humidity. It's pleasant going in our basement; it never smells moldy or like mildew. It's doing a great job! The basement is about 900 square feet.”

Looking for a portable dehumidifier you can transport from room to room? With caster wheels and side handles, this handy pick is easy to move throughout your home to eliminate excess moisture. It works best in small to medium rooms, therefore is an excellent choice for bedrooms, laundry rooms, and garages. Short on space? Simply wheel the machine into storage when you don’t need it. 

A helpful control panel allows you to set your desired humidity level and check the device’s water levels. If you’re not using the continuous drain option, the machine will automatically shut off when the water tank is full. Its front-loading bucket, handle, and splash guard make the emptying process simple—plus, the removable filter can be hand-washed in the sink. While most humidifiers should only be used in spaces between 59 and 86 degrees Fahrenheit, this particular model is suitable for temperatures down to 41 degrees Fahrenheit. 

With nearly 5,500 five-star Amazon reviews, this dehumidifier is praised for its convenience, high-end features, and bucket design. “This dehumidifier is small but mighty,” one reviewer raves. “With Oklahoma’s high humidity, I have been pulling over two of the detachable buckets of water, which are at least a gallon, out of the air daily. I use the water for my potted plants, so this product is a win-win. Portable and easily accommodated.” 

Although the reviews are mainly positive, some do mention that the machine can be a bit noisy when running on the highest setting.

This sleek choice is Wi-Fi-enabled and can be controlled via the brand’s app. An included cord winder makes storage less messy, too. There’s no complicated setup with this one, but the brand does have a customer service hotline in case you do run into any issues or need assistance. 

This durable model takes approximately 70 pints of moisture out of the air each day and comes with a drain tube if you’d like to use the continuous drain function. Covering up to 4,000 square feet, it works double-time to reduce dust in the air with a washable dust filter. 

Most-loved for its techy features, elegant design, and easy installation, this dehumidifier gets great feedback on Amazon. One reviewer writes, “Main features that influenced this purchase was the Wi-Fi capability and the fact you could use a drain hose instead of having to constantly empty the bucket. The Wi-Fi setup was easy and took less than two minutes.” Others comment on how quiet it is compared to other options, and how easy it is to move around because of the built-in wheels. 

Most negative reviews come from people who have issues with the app specifically.

Ideal for larger spaces, this powerful dehumidifier reduces moisture in the home and has an optional built-in pump compressor. The sleek design features built-in wheels for easy transport throughout your home. It operates quietly, so you don’t have to worry about the noise interfering with your television shows or work calls. 

Each machine runs on a 24-hour cycle and automatically shuts off once the water tank is full. If you don’t opt to use the pump, you’ll just need to pour the water out manually, or use the drain outlet to install a hose for continuous draining. An Energy Star-certified product, this is an excellent choice for anyone who wants to use less energy. 

Featuring a whopping 38,000 five-star ratings on Amazon, this popular choice gets a lot of love. If this customer’s detailed review doesn’t convince you, we don’t know what will: “I've purchased this dehumidifier three times now. Not because the first two had any problems, but because they worked so well on the spaces I've used them in. Whether it was the basement, garage, or poorly insulated apartment, the amount of water this machine extracts from the air is surprising and impressive. Most recently, it took the humidity in a 500 square foot space from around 65% down to 45% in about an hour or two. It's already begun to feel very good for my respiratory system. And in the aforementioned basement, it put an end to a longtime mold problem very quickly.” 

One qualm a few people mention is that the machine’s humidistat operates in increments of five and is not always the most accurate.

Featuring a double dehumidification condenser, this portable and affordable dehumidifier works well in rooms up to 720 square feet. An auto shut-off function makes it safe to run when you’re not home—so you won’t have to worry whether or not you left it on. 

This unit features a high-power mode, which is great to use during the day, and a whisper-quiet sleep mode that’s particularly well-suited for nighttime. Another unique touch is the ambient “breathing atmosphere light” detail (but this can be turned off if you’re not a fan). The brand provides lifetime customer service and tech support 24 hours a day, which can be helpful if you ever need assistance. 

As one reviewer puts it, “If you are looking for a dehumidifier look no further. This dehumidifier was well within the budget and did the job very well. I have about a 300 square foot basement and the dehumidifier had no issues keeping up. After it was running for about a day the basement was noticeably different, and it felt very comfortable to be down there. There's no need to purchase an expensive brand of dehumidifier when this one does the same job just as well.” 

Although most users are satisfied with this dehumidifier, some wish it came with a few more features, such as the ability to restart automatically if the power cuts out.
