Best Dehumidifiers Updated November 2018

Conclusion

Pros

Cons

Frigidaire

Energy Star Dehumidifier
Check Price at: 1 store
This large, customizable humidifier can hold 70 pints, so you won’t need to constantly empty it.
We liked the modern design and its custom timer and humidity settings.
At 47 pounds, it’s not super portable. The noise level is debatable. Some say it’s loud while others weren’t bothered by it.

Keystone

Energy Star Dehumidifier, 50-Pint
Check Price at: 1 store
The Keystone is effective, energy-efficient, and an extremely quiet dehumidifier. However, the continuous fan is a bit finicky.
This durable machine on wheels does the trick at a fair price. The Energy Star compliance was important to us and our team didn’t notice any noise as we worked nearby.
Some customers don’t like the continuous fan. It can flood if you’re not on top of emptying the bucket.

LUOYIMAN

Electric Home Dehumidifier
Check Price at: 1 store
A compact option that’s ideal for a bathroom, closet, or small bedroom with light to moderate moisture, as it’s slow to fill.
We loved the UV light that removes formaldehyde, bacteria, dust, and smoke. You’ll have cleaner, drier air with this humidifier.
It fills slowly. Some customers report issues overheating, so be sure it’s clear of furniture and has enough ventilation.

Eva-dry

Electric Petite Dehumidifier
Check Price at: 1 store
This small dehumidifier packs a punch, working quickly to dehumidify your space for a fraction of the price.
It works quickly for such a small dehumidifier. This portable dehumidifier weighs less than 7 pounds and costs less than $50.
Some customers who used the product daily report it cutting out after 6 months to a year.

hOmeLabs4

4 Gallon 30-Pint Dehumidifier
Check Price at: 1 store
Keep in mind that the listed 4-gallon capacity is only on continuous mode when it’s hooked up to a hose. It comes with the outlet, but not the hose itself.
It’s versatile, as it works well in any average-size room. It also automatically shuts off when it’s at capacity.
The 3-liter water tank capacity fills up fast. To remove the 4 gallons listed in the description, you will need to use a hose rather than the bucket.

Too much moisture can damage your house, personal items, and health. Enter dehumidifiers. They come in all shapes and capacities with several features to consider. The thousands of dehumidifier reviews, questions, and comments can be overwhelming too, so the House Method Reviews team did the work for you. We synthesized customer reviews and even did our own testing to find the info you need to buy the best dehumidifier that can get your space back to the clean, comfortable home you love.

Dehumidifier reviews guide 

Excess moisture can be a major problem in some regions or sometimes even just certain homes. Moisture in your home creates that “sticky” feeling—like you’re walking into a tropical forest—that’s simply unpleasant to come home to. That feeling not only affects the air, but your home’s interior as well as your clothing, food, and health. The moisture can result in potentially dangerous traces of mold, mildew, and bacteria.

In any scenario, a dehumidifier is a step in the direction of immediate change in moisture levels and comfort of your home. They can be used temporarily to halt a major issue, like mold infestation, or you can use one regularly to keep water levels low and prevent mold and mildew from forming.

We’ve chosen five of the best dehumidifiers that can help keep the air in your home crisp and clean. These products can sometimes be costly though, so it’s important to know your machine will be reliable and effective. The products we reviewed above have proven themselves to us and many verified customers, like you. If you’re unsure how it works or what to look for, refer to our guide below before you buy.

How it works

Dehumidifiers use fans to draw air into the unit. When the air passes through the unit, cooling coils pull moisture from the air by lowering its temperature. The removed moisture is collected in a reservoir. Then, it heats the air and distributes it back into the room moisture-free.

You have two options for water collection in your unit. You can either collect water in a bucket, which you will need to empty once it has reached capacity, or you can set up a hose to continuously empty water into a sink or floor drain. The right option for you depends on the moisture levels in your home, the maintenance level you want (or want to avoid), and how much you’re willing to spend on your electric bill to power the machine. Review the product details to find out whether the hose is included with your purchase. Sometimes they include outlets but not the hose itself, so you may need to purchase one separately.

You can find dehumidifiers with different features and controls, but all work in the same fundamental way. They pull moisture from the air in the surrounding area, separate moisture from the air, and return the air back into the room to make your space more pleasant and safer.”

Best dehumidifier for large spaces with moderate moisture KEYSTONE ENERGY STAR DEHUMIDIFIER, 50-PINT

This model is large enough to serve your larger spaces (up to 3,000 square feet) and it’s likely to use less energy and make less noise than larger models. If you’re not dealing with serious issues and just looking to reduce the feeling of humidity in your home’s largest rooms, then try this model. It is Energy Star compliant, so even in continuous use, you can rest assured your unit is working as efficiently as possible. Disclaimer: Go for the hose—rather than the bucket—if you’re going to use continuous mode.

3 Major factors to consider

Size

These machines come in a range of sizes to fit your different needs. Small dehumidifiers—about 16-ounce capacity—are great for low-grade moisture issues in small rooms, like closets or bathrooms. If you need to cover more space, like a living room or open floor plan home, go for a larger machine that has a 50- to 70-pint capacity.

Humidity settings

Many dehumidifiers allow you to set the humidity level you’d like it to maintain. After you set the humidity level, the unit should automatically shut off once the level is reached. This is important for heavy-duty machines that can sometimes overcorrect the issue and create dry, uncomfortable air. If you’ll want this feature, be sure to check for humidistats and humidity control settings on your unit.

Continuous mode

If you’re dealing with serious moisture issues, continuous mode might be the choice for you rather than an automatic shut-off, which could only scratch the surface of your moisture problem. For continuous mode, use the drain hose rather than the bucket to avoid overflowing from the reservoir. Look for energy efficient dehumidifiers to reduce electricity usage as much as possible.

High humidity (more than 50% humidity) at home can increase allergens and mold problems, but air that is too dry (less than 30% humidity) can make asthma worse.”

Best dehumidifier for small spaces EVA-DRY ELECTRIC PETITE DEHUMIDIFIER

If you’re just looking to reduce moisture in small spaces, like a bathroom or closet, this unit is a great choice at a great price. While other products of this size can be slow and ineffective, this dehumidifier really works well for its stature. It’s effective up to 106 square feet and holds up to 16 ounces of water.  And don’t worry, it automatically shuts off when full. Whisper Technology puts it in the quiet dehumidifier category.

Do’s and don’ts of using a dehumidifier

  • Do use a dehumidifier to reduce and maintain humidity levels.
  • Don’t assume the unit will eliminate a major mold or mildew issue. Dehumidifiers are great for damage control and maintaining humidity levels, but they won’t eradicate the root cause if you’re dealing with a major mold infestation. Be sure to get a professional’s opinion if you’re noticing surface mold on your tile, walls, and clothing or personal symptoms of congestion.
  • Do use in a damp space, like garages, laundry rooms, bathrooms, and basements.
  • Don’t use in dirty rooms. Dehumidifiers produce airflow, which can circulate a lot of dust and debris in a dirty room. Vacuum and dust before using a unit.
  • Do consider units with minimal noise or automatic shut-off features to prevent disruptions while you’re relaxing in your home. You can also schedule on and off periods based on when you’re out of the house versus settling down to relax at home.
  • Don’t place in areas that block the input or output. As much as you’d like to tuck your unit in the corner, you’ll limit its effectiveness if it’s touching or blocked by furniture, curtains, or walls.

Look for the following signs to know if you need to address the moisture in your room or home: traces of mold on ceilings or walls, condensation on windows, musty odors, worsened allergies or congestion.”

Best dehumidifier for basements FRIGIDAIRE ENERGY STAR DEHUMIDIFIER

The Frigidaire is a great unit for large spaces—it can be a whole-house dehumidifier. It’s an especially good choice if you’re struggling with mold and mildew in your home. If that’s the case, set up the hose and run it on continuous mode. In fact, you can program your humidity level settings so it doesn’t overcorrect and dry out your home. This unit has the most capacity and power of all the products we reviewed. And being Energy Star compliant means it does all that work as efficiently as possible. Plus, its modern, sleek design makes it less of an eyesore in high-traffic areas, like the living room.

Don’t forget to clean your dehumidifier filter, especially if it runs frequently in a moist, less-than-sparkling-clean area, like the basement.”

Frequently asked questions

What dehumidifier brand is best?

For legitimate dehumidifying needs—think large spaces or a home with a lot of moisture—the best choice is Frigidaire. It has a 70-pint capacity and customizable settings to get the humidity levels and runtime just right. It works well, fast, and it’s not too bad to look at either.

If you need to control moisture in a smaller space, like the master bathroom, consider a mini dehumidifier like the Eva-dry Electric Petite Dehumidifier.

What size dehumidifier do I need?

The size of the area you’re working with will determine how large of a dehumidifier you need. Mini dehumidifiers (like the Eva-dry Electric Petite Dehumidifier) are great for small rooms and typically run with a few gallons of capacity if you hook up a hose for continuous use. If you’re using yours in an open floor plan or basement, consider 50- to 70-pint dehumidifiers, such as the Frigidaire Energy Star Dehumidifier or Keystone Energy Star Dehumidifier.

How much does a dehumidifier cost?

Price is based on size and capacity. Small dehumidifiers range from $40 to $80. Mid-sized to large dehumidifiers cost between $130 to $200.

Are dehumidifiers expensive to run?

Dehumidifiers can run up your electricity bill if you overlook usage amounts or the energy efficiency of your machine. Reduce costs by putting your unit on auto shut-off and look for units that are Energy Star compliant.

Do dehumidifiers use a lot of electricity?

Many dehumidifiers are energy efficient. Look for the energy factor detail in the product description. The energy factor is measured in liters of water removed per kilowatt-hour (L/kWh). Units labeled as Energy Star compliant is a more obvious indicator that they’re energy efficient.

Do dehumidifiers shut off automatically?

Many dehumidifiers have an auto shut-off setting that will turn the fan off when the unit reaches a certain humidity level. You can control this on many models, such as the Frigidaire Energy Star Dehumidifier.

Note: Continuous mode means the fan will not shut off until it’s manually turned off. This mode is better for bigger problems (a flooded basement) that require constant air circulation and continuous drainage. However, it’s more maintenance if you don’t fasten a hose to the unit instead of relying on the bucket, which can easily overflow if forgotten.
