The available sleep mode serves to conserve energy, although the entire unit is ENERGY STAR®-rated, and there is custom humidity control so that you can customize the unit to the room. This dehumidifier will work in temperatures as low as 41 degrees Fahrenheit, and it comes with a washable filter for simple cleaning while it absorbs dust from the air.

Several features include a sleep timer and continuous 24-hour cycle with auto shut-off, restart, and defrost functions. The included drain hose outlet allows for constant draining without constant supervision, freeing up your day. 

The box comes loaded with a three-prong grounded power cord, a removable, washable filter, and a removable water tank. Performance is strong, too, thanks to a built-in pump compressor.

How did we choose these dehumidifiers?

We consider several factors when choosing the best dehumidifiers for home and work. 

  • Size: Some units are designed for portable use, often tasked with smaller spaces like a single room or office. However, units designed to tackle larger spaces, such as an entire home, will likely be much heavier and less portable. 
  • Features: From smart capability to automatic alarms and alerts, there are a lot of features to sort through when you are choosing the best dehumidifier.  
  • Pump: Many of the best dehumidifiers incorporate a built-in pump and hose, so you do not have to manually dump water every time you need to reduce moisture in the air. 
  • Cost: As seen here, budget can vary significantly when searching for the best dehumidifier. The size of the dehumidifier, as well as its features, can greatly impact cost, so it is important to shop your options so that you can find the best budget-friendly dehumidifier for your needs. 

We recommend that you compare features and pricing to ensure that the model you choose is the best dehumidifier for your personal needs. 

How do dehumidifiers work?

Dehumidifiers work to reduce moisture in the air by using a compressor or desiccant rotor. Warm air enters the machine and then passes through cooling coils that suck out the moisture and instead release dry air back into the room. Moisture taken from the air is condensed into water droplets that are kept in a bucket until full. 

What size dehumidifier do I need?

When determining what size dehumidifier you need, first look at the affected area. If it is a larger space, a small, portable dehumidifier will not be your best option. This chart can help.

Room size

Recommended dehumidifier capacity


400 - 600 sq. ft.

65°F: 20-25 pints 

80°F: 30-40 pints


800 - 1,000 sq. ft.

65°F: 30-35 pints 

80°F: 50-60 pints


1,200 - 1,500+ sq. ft.

65°F: 40-55 pints 

80°F: 70-90 pints

How much does a dehumidifier cost?

A dehumidifier can range from a few hundred dollars to several thousand dollars, depending on the size of the dehumidifier that you need. Other factors that can impact price include the type of features that you choose. Our picks for the best dehumidifiers range in cost from around $260 to more than $1,300 each.

Are there alternative dehumidifiers worth considering?

In our search for the best dehumidifier, we found many options that may be worth a second look. These are some of the dehumidifiers that almost made our list:
