  • Dehumidifiers remove excess moisture from your home to prevent mold buildup and remove allergens from the air.
  • The top-rated Frigidaire FFAD7033R1 dehumidifier is the best one because it removes moisture from the air leaving you with a comfortable and healthy living environment.

Excess moisture in the air can cause substantial damage to items in your home and your health. A good dehumidifier removes excess humidity from the air, which can help prevent mold and mildew buildup and eliminate allergens. Dehumidifiers are often placed in basements, but there are other use cases for them, such as in closets where you store damp clothes or other smaller areas where too much moisture can cause a problem such as bathrooms, RVs, boats, and more.

Dehumidifiers fan-force air over coolant-filled coils to remove moisture. The remaining condensed moisture then drips from the coils into a bucket or basin, or it may be pumped out of the unit depending on the model. As a result, drier air is expelled back into the room.Advertisement

A dehumidifier helps maintain an ideal relative humidity level (RH level) in your home. Relative humidity refers to the ratio of the current absolute humidity to the highest possible absolute humidity. According to the American Society of Heating, Refrigerating and Air Conditioning Engineers (ASHRAE) Standard Environmental Conditions for Human Occupancy, it's recommended you keep relative humidity between 30% to 50% in the summer and 30% to 40% in the winter.

How to choose a dehumidifier

When selecting a dehumidifier, it's important to consider the size of the area you wish to dehumidify, along with the condensation moisture removal method, and the amount of power you expect the machine to consume.

At their most basic level, dehumidifiers vary according to pint removal capacity every 24 hours. Moderately damp areas will require between 25 and 40-pint capacity, while extremely moist areas will need between 40 and 70-pint capacity, all dependent upon the size of the area you wish to dry.

Unless you plan on removing and clearing the water basin constantly, you'll want to go with a direct drain feature, which allows for continuous operation without emptying the unit's bucket. Direct drains are convenient but typically require a floor-level water drain. If that's not an option based on your layout, opt for a unit with a pump, which can push water into a specific space, such as a basement sink.

Dehumidifier energy performance is rated by the amount of water extracted every hour versus the amount of energy consumed to do so. Low-level units usually consume less power, but they may not be effective enough for your humidity needs. To get maximum efficiency out of any unit, look for those that are ENERGY STAR certified. Also consider the following:
  • The filter indicator setting alerts you when the air filter needs to be cleaned.
  • The auto-humidistat senses the moisture level in the area around the unit and automatically shuts the unit off to save energy once the desired humidity level is reached.
  • A low-temperature setting allows the unit to operate in temperatures as low as 41 degrees Fahrenheit.
  • Auto-defrost keeps units from freezing in colder environments (usually below 65 degrees Fahrenheit).
  • Auto reset restarts the unit to its previous setting after a power loss.
The following picks are based on online research, ratings from review and dehumidifier-specific sites, Amazon ratings, and customer reviews. They're intended for commercial use and we've included picks for different sized areas ranging from spaces as small as a gym bag to an entire apartment.

The best portable dehumidifier

The best portable dehumidifier
Space is no longer a restriction with the super portable and affordable Eva-Dry E-333 Portable Dehumidifier.

Humidity is everywhere, which is why this Eva-Dry E-333 Portable Dehumidifier is a must have for smaller areas. The handheld 5-by-5-inch device can be placed anywhere extra humidity clogs up the air such as in closets, under your kitchen sink, in safes, boats, RVs, or bathrooms, and more.

Each Eva-Dry E-333 Portable Dehumidifier helps to eliminate excessive humidity for up to ten years using renewable silica gel technology that works without batteries or external power. Without the need for a power source, the portable dehumidifier is completely silent, but it's powerful enough to provide a humidity-solution in any area up to 333 cubic feet.

The dehumidifier is renewable, meaning it will not require any expensive refills, and comes backed by a 5-year warranty. The product works on a cycling system in which you place it in a damp area to soak up moisture and then remove it to charge.

As the unit absorbs the humidity, there is an indicator window containing crystals that will change from orange to green over the course of two to four weeks or as the device collects between 8 and 10 ounces of moisture. When the crystals have changed to green, this indicates the dehumidifier is ready to be renewed or plugged in for 8 to 10 hours in a well-ventilated area, and then placed back in the area you wish to remove humidity from. The product is designed to be used in this way for up to 10 years as it captures moisture in the air without any leaks or spills.

Consumer Search and Faveable both rate it highly. On Amazon, the product holds a 4.2 out of 5-star average based on more than 2,000 reviewers.

Many Amazon reviewers are pleasantly surprised to learn the product exists, while others are more than satisfied with the low price or that the tiny device works so well. Critical reviews tend to center around the fact that you have to check it from time to time, or that it's really best for small spaces such as safes, rather than medium-sized spaces such as cars.

Pros: Extremely portable, low price, does not need a constant power source, completely quiet

Cons: Requires charging, best for small spaces
