The Best Dehumidifiers On The Market

Last Updated on

We understand that needing a dehumidifier in your home is a frustrating experience. Humidity has a way of zapping energy, and as a result, patience levels inevitably drop. That's why we've compiled this review of the best dehumidifier options for you. In this review, we demystify the dehumidifier buying process. Later, we explore the top dehumidifiers for residential use.

Best Dehumidifier FAQ

If you have questions about buying the right dehumidifier for your home, this is the place to start. Below we answer the most frequently asked questions about humidifiers.

1. What Is a Dehumidifier?


Dehumidifiers are electronic appliances that draw in and collect moisture from the air.

2. How Does a Dehumidifier Work?


Each dehumidifier works differently based on the technology it uses. Some dehumidifiers use a refrigeration method to chill air for water removal. Absorption dehumidifiers suck air into an absorbent material to trap water. Both types of dehumidifiers separate water from the air and collect the extracted water within the machine for draining.

All dehumidifiers come with a condensation bin to store the collected water. Most also feature a drainage valve to hook up to a hose for continuous draining. Continuous draining is crucial when you want to run the dehumidifier without regularly emptying the water tank. If you already know that you'll use a continuous draining feature, look for models that come with a drainage hose.

3. How Do I Know If I Need a Dehumidifier?


Determining if you need a dehumidifier at home is an entirely sensory experience. If you see damaging mold, mildew, of wet spots anywhere in your home, it's a good idea to invest in a dehumidifier. Moisture in a home can cause health issues and damage your property. Condensation covered windows are another indicator of excessive humidity inside as is a musty smell. Finally, how you feel can point you to humidity levels. Rooms with high humidity feel stuffy and uncomfortable even when air is flowing.

4. What Can a Dehumidifier Help With?


Humidity is a powerful opponent that can wreak havoc in ways you might not realize. The benefits of using a dehumidifier include:

  • Improved breathing air quality
  • Mold prevention
  • Increased energy
  • Eliminates dust mites
  • Reduces airborne allergens
  • Improved home aroma
  • Food stays fresh longer
  • Lowers energy costs
  • Improves skin

5. Which Dehumidifier Is Right for Me?

Finding the right dehumidifier for your home might seem tricky at first because of the sheer number of options out there. The review below highlight some of the best dehumidifier choices for you, but here's a crash course in how to decipher dehumidifier lingo so you can find the right device for your needs.

Size

Choose a dehumidifier size based on the space's size plus how wet it is. An extremely wet 1500 square foot room needs a bigger dehumidifier than a damp 2,500 square foot room.

Basements and cellars are often some of the wettest rooms in a home. If a very wet basement is 1,000 square feet or more, choose a dehumidifier that can process 60 pints or more. A 40-pint dehumidifier suffices for damp or slightly wet areas up to around 1,000 square feet.

Keep in mind that larger dehumidifiers work more efficiently in any space, but an area under 500 square feet never requires a large dehumidifier.

Capacity

When researching dehumidifiers, you notice that each option mentions how many pints the machine can process, which is the device's capacity. That number is the amount of water the dehumidifier can take in during a 24-hour time frame, not the size of the condensation tank. Water tanks are small, and unless you hook up a hose for continuous draining, you must empty the tanks frequently.

Noise

Noise is one of the most common concerns with dehumidifiers. Some operate extremely quietly while others do not. Noise concerns aren't as pressing when the dehumidifier is placed in an unused area of the home. It's a big deal if you are using it in your bedroom or living space. If noise is an issue for you, look for quiet dehumidifiers in the review below.

Heat

Many people who use a dehumidifier do so to make the ambient temperature in their home tolerable during scorching summer days. If this applies to you, look for a dehumidifier that doesn't create excess heat when it's turned on. Some dehumidifiers are better than others for use during the summer.

Costs

Most dehumidifiers these days are Energy Star Certified, which can cut electrical usage costs. Running any machine will cost money. When looking for the most cost-effective dehumidifiers, always look for the Energy Star certification to keep your bills as low as possible.

​Low Temperature

Humidity isn't just a summer problem, and many people need to use a dehumidifier in the winter. If this applies to you, look for a model that works in low temperatures. Low-temperature dehumidifiers can function even when a room or space is as cold as 41 degrees Fahrenheit.
