Best for Basement: hOmeLabs 4000 Sq Ft Dehumidifier 70 Pint Energy Star
Basements frequently need dehumidifiers, as they tend to be wetter than other areas of the home and are therefore more prone to mold and mildew. If you’re looking for a dehumidifier to keep your basement free from moisture, one of the best options is the hOmeLabs Dehumidifier, which can handle rooms up to 4,000 square feet.
This product can pull up to 70 pints of water from the air every day, and it has a 6-liter water tank. It will automatically shut off when the tank is full, or you can hook it up to a hose for continuous draining. It has a quiet fan that won’t interrupt your daily activities, and it’s Energy Star-certified, so it won’t drive up your electricity bill too much. Reviewers love that this dehumidifier is sleek and easy to use, and many note that it's good at preventing mold from growing.

Best with Pump: BLACK + DECKER 70-Pint Energy Star Portable Dehumidifier with Built-in Pump
With most dehumidifiers, the built-in drain uses gravity to empty water from the tank, so you have to set up the hose in a particular way. However, if you’re willing to spend a little more, you can get a dehumidifier with a pump—this way, it will pump the liquid out to an external receptacle of your choosing, and you can even have the drainage hose set up vertically.
One of the best dehumidifiers with a pump is the BLACK + DECKER 70-Pint Energy Star Portable Dehumidifier. This unit can remove up to 70 pints of water from the air each day, and it’s Energy Star-certified as well. It has three fan speeds and an adjustable thermostat with a digital display. Like most, this dehumidifier works best at temperatures higher than 41 degrees, and it includes caster wheels that make it easy to transport from room to room. Reviewers call this model “the best dehumidifier ever,” writing that a built-in pump is great for those who don’t want the cumbersome task of emptying the water reservoir.Continue to 5 of 8 below.

Best Small: Eva-Dry Petite Dehumidifier
Most dehumidifiers are fairly large and expensive, but if your needs are more modest, you might like the Eva-Dry Electric Petite Dehumidifier. This unit can remove up to 8 ounces of moisture from the air each day, and it gets rave reviews from users who love its performance and price point.
Because of its size (it measures 6.38 x 11 x 5.25 inches), the Eva-Dry is ideal for laundry rooms, bathrooms, closets, offices, RVs, and boats. It can sit on a counter or shelf to save space, and the noise from the unit's small fan is negligible. At its low price, the Eva-Dry doesn’t boast a lot of extra features, but it has a simple on-off button, a full-tank indicator, and an automatic shutoff.
Though this unit's reservoir only holds only 16 ounces of water at a time, users like how compact it is and don’t mind emptying the tank frequently.

Best for Bedroom: Tosot 30 Pint 1500 Sq. Ft. Energy Star Dehumidifier

One of the quietest options available right now is the Tosot 30 Pint Energy Star Dehumidifier, which operates at just 48 decibels on the low setting—the manufacturer equates this to the sound of light rain. Kind of soothing, right?
Additionally, the Tosot Dehumidifier can remove up to 30 pints of moisture from your home per day, and it’s Energy Star-certified, to boot. It’s ideal for spaces up to 1,500 square feet, and in the event of a power outage, the product will automatically restart itself. You can use a garden hose to continuously drain the unit, or you can empty the drain bucket manually. Reviewers give this dehumidifier top marks, saying it’s attractive and quiet. Many note it can be used throughout the house, including in basements, garages, the kitchen, and more—essentially anywhere you’re looking to reduce moisture and humidity.

Products Tested by The Spruce
How We Tested
We bought three top-rated dehumidifiers that our reviewers tested for days on end. We asked our testers to consider the most important features when using these dehumidifiers, from their capacity to their performance. We’ve outlined the key takeaways here so that you, too, know what to look for when shopping.
What to Look for in a Dehumidifier
Capacity The most common dehumidifier capacities are 30, 50, and 70 pints — this refers to how much water the unit can remove from the air in 24 hours. Thirty-pint units are often suitable for moderately damp spaces up to 2,500 square feet, but wet or extremely wet spaces of that size are better served by a 50-pint unit. Larger 70-pint units are for bigger homes and spaces.
Water removal In very moist areas, dehumidifiers with tanks will have to be emptied frequently — if they’re not emptied, the unit will shut off. This is particularly inconvenient if you’re not home to empty the tank. Look for a direct drain feature to avoid this problem, but note that you’ll need a floor drain or a unit with a hose that can drain into a nearby sink or tub.
Features Make sure to look for user-friendly digital controls. Opt for a unit with a built-in hygrometer, so you can set — and maintain — the correct humidity level. A defrost feature is also useful, since it’ll shut the unit off if it’s too cold. If noise is a concern, choose a dehumidifier with two-speed fans, since these models run quietly at low humidity levels.

What We Like
What We Don't Like
One of our reviewers, who tested this dehumidifier in a typically hot and humid room, was very impressed with its performance. “It’s done a great job at removing the mildew smell we have upstairs,” he noted, “and we plan to use it in our basement when we move.” One tester was also pleasantly surprised at how quiet it was. In terms of drawbacks, our testers wished this model weighed a bit less and could deliver the same power in a smaller size.

May require frequent emptying
“Buy the Frigidaire 30-Pint Dehumidifier with Effortless Humidity Control if you’re looking for an affordable and sleekly designed powerhouse that can pull 30-pints of liquid from the air in as little as eight hours,” our tester declared. Our reviewer also liked how lightweight and easy it is to move, as well as the glossy finish, which makes cleaning it a breeze. On the other hand, she cautioned it “may be too noisy for smaller rooms or everyday spaces.” Our tester also noted it requires frequent emptying unless you set up continuous draining. Overall, though, she said, “For a cost-effective dehumidifier, this is definitely worth the purchase.”

What We Like
Great customer service
Helpful guides and instructions
What We Don't Like
Manual mode needs improvement
Somewhat difficult to move around
Water can slosh out easily
While this wasn’t our tester’s favorite dehumidifier, she said, “It’s a bit cheaper than other options and definitely does its job (especially if you're using it in continuous drainage mode).” The pluses? “The settings are very user-friendly and the packaging design was thoughtful,” our reviewer noted. “This model is also a few pounds lighter than comparably-sized units and their customer service was accessible and helpful.” In terms of negatives, she thought the manual setting could use improvement and “emptying the water bucket was just a bit clunky.” She also wished for better handles and locking wheels to make moving it around easier.
