The best dehumidifiers contribute to healthy indoor environments. A dehumidifier is useful to keep relative humidity at a comfortable level — no higher than 30 to 50 percent. When excess moisture (high humidity) is present in homes, offices, basements, or any indoor space, several problems may occur, including mold and mildew, malfunctioning electronic devices, rusting metal objects, and growing viruses, bacteria, dust mites, and fungi may grow.

To combat these problems, dehumidifiers draw moisture from the air. A fan pulls the humid air into the machine, where it passes through dehumidifying coils. As the moisture is extracted from the air, it condenses into water droplets that collect in a receptacle tank. The dehumidified air is then expelled out into the room as warm, dry air. 

Users may empty the water tank manually, or they may attach a hose that continuously drains the water away from the unit. Pumpless dehumidifiers depend on gravity for continuous drainage, directed toward a floor drain. Alternatively, units with built-in pumps can drain water both horizontally and vertically. The pumping action allows the water to be directed to a sink, a sump pump, or out a window. Whether they feature pumps or pumpless operation, the best dehumidifiers protect both indoor environments and users’ health from the harm that may result due to excessive moisture in the air.

How We Selected These Products

To develop our list of recommended dehumidifiers, we started with research. First, we looked into how dehumidifiers work, as well as why they contribute to healthy indoor environments. Next, we consulted seven buyers’ guides to find dehumidifiers that receive the highest ratings from customers and reviewers. Finally, we looked into 19 different models of dehumidifiers from nine different companies. In addition to reading the information included on the Amazon product pages, we researched each dehumidifier on its manufacturer’s website. This additional research provided enhanced detail for our understanding of each machine’s features and capabilities.

As we continued to conduct research and expand our understanding of the products, several features emerged as important differentiations among dehumidifiers. These include the following:

  • Capacity, measured in the number of pints of moisture extracted from the air in each 24-hour period
  • Ability to continuously drain
  • Built-in pump or pumpless operation
  • Customizable, pre-set humidity levels
  • Noise levels (related to fan speeds)
  • Wi-Fi connection capability

We also looked for dehumidifiers that offer value and useful features for both large and small spaces.

On the other hand, the option of manually emptying the water tank is convenient due to its front-of-the-unit location, carry handle, and splash guard.

This unit shuts off automatically when the water tank is full. Therefore, leakage is not a problem. Additionally, it features a 24-hour on/off timer. The dehumidifier extracts and removes 50 pints of moisture from the air over a 24-hour period. 

The Frigidaire dehumidifier is designed to work at high or low temperatures, down to 41 degrees Fahrenheit. A customizable humidity control allows users to choose their personal comfort level. Additional features include a humidity sensor, frost sensor, and automatic restart. The air filter is removable and washable, facilitating the removal of allergens from the air.

With an Energy Star certification, this dehumidifier is an efficient energy saver. Moreover, it operates quietly. On the lowest of its three fan speeds, the sound level is 47 dBA (approximately the noise level of a quiet library).

Best Runner-Up: GE Energy Star Portable Dehumidifier 50 Pint with Pump

The built-in pump and the included hose move water toward a drainage point up to 16 feet away from the unit. The pumping action allows the water to move in an upward direction to empty into a sink or out through a window. This continuous drainage feature means users do not need to manually empty the water tank. 

On the other hand, if users choose not to utilize the automatic pump and hose, they can manually empty the water tank, which is conveniently located on the front of the unit and features a sturdy carrying handle. The machine sounds a 10-second alarm if the tank is full or missing while the dehumidifier is in operation.

GE provides a Smart Dry feature, a mechanism that allows the dehumidifier to sense the humidity level in the atmosphere and automatically adjust the fan speed. Therefore, the unit works only as hard as necessary to remove the existing moisture in the air. This handy feature saves on electricity and increases the machine’s efficiency. On the other hand, users may customize their comfort level by manually selecting from three fan speeds. The digital controls and LED read-out make it easy to change the settings. 

Additional conveniences include a 24-hour on/off timer, an automatic defrost feature, and a slide-out filter. An auto-alert reminds users to remove the filter and clean it after every 250-hour period of operation.

On the other hand, the continuous drainage feature eliminates the need to empty the tank. This unit does not have a built-in pump, so it drains via gravity, carrying the water through a hose to a drain at a lower level than the dehumidifier. This is an ideal set-up in a basement where a floor drain is available. The hose is not included, but a standard garden hose works with the unit.

Things to Consider When Buying the Best Dehumidifier

Several factors differentiate the dehumidifiers available on the market today. Shoppers may want to consider these qualities and features as they explore the viable options.

Pints-per-Day Capacity

Dehumidifiers are classified by how many pints of moisture they can extract from the air in one 24-hour period. Shoppers should consider their needs in terms of the size of their space and the level of humidity they want to decrease. For example, a large, damp basement requires a more powerful dehumidifier than a small, slightly humid bedroom. Then, shoppers may look for a dehumidifier with the corresponding pints-per-day capacity. The most common capacity is 50 pints per day, and it’s considered adequate for a medium-large bedroom or living room. Alternative options include 70-pint-capacity units or smaller ones with 20 to 30-pint capacities.

Built-in Pump or Pumpless

To avoid the chore of manually emptying the water tank, shoppers may look for dehumidifiers with a continuous drainage feature. A hose is attached directly to the tank to carry water away from the unit toward a floor drain, sink, sump pump, or out a window. If the unit has a built-in pump, the pumping action can direct the water upward as well as downward and horizontally. If the dehumidifier does not have a pump, the only option for continuous drainage is to allow gravity to carry the water toward a floor drain.

Automatic Features

Dehumidifiers feature varying mechanisms for convenient, automatic operations. These include 24-hour timers that allow users to set the machines to automatically start, stop, and operate for specified periods each day. The humidistat automation involves the capability to pre-set a desired humidity level and have the machine start and stop itself accordingly, maintaining the prescribed level of comfort.

Portability, Noise Level, and Energy Star Rating

All of the dehumidifiers in our list of recommendations include carry handles and rolling wheels or casters for portability. Additionally, most are Energy Star certified, demonstrating that they meet federal guidelines for energy efficiency.

Dehumidifiers operate with fans that draw the humid air into the machines, and they typically offer two or three fan speeds. Specifications include the noise level produced by the fans. These levels are measured and reported in A-weighted decibels (dBA). A dBA of 46 is very quiet, similar to the sound level in a quiet library.

FAQs

Q: Do you need to purchase replacement air filters for dehumidifiers?

No. The air filters are removable and reusable. They are easy to clean and do not need to be replaced.

Q: When should I use a dehumidifier?

Most users operate their dehumidifiers in the spring and summer to eliminate dampness and the sticky feeling of high humidity. Use a dehumidifier if you see signs of mold, mildew, or damp walls.

Q: Should I turn my dehumidifier off in the winter?

If the temperature or the humidity drop below a comfortable level, you should turn off the dehumidifier. If the coils freeze, the unit may be seriously damaged.

Q: Are dehumidifiers a good idea?

Dehumidifiers are a good idea to promote a healthy indoor environment. In addition to removing moisture from the air, these units help get rid of dust mites and allergens. They also help prevent the growth of mold, mildew, bacteria, and fungi.

Q: Where is the best place to put a dehumidifier in your house?

Put a dehumidifier close to the source of excess moisture or dampness. Many people use dehumidifiers in their basements, crawl spaces, bathrooms, and kitchens.
