6 Best Dehumidifiers of 2022, According to Experts

Record temperatures are sweeping the country, forcing homeowners to start their air conditioning units. And while that helps get rid of the heat, it doesn’t necessarily solve the dampness problem, which means another major problem could be lurking in your home: dampness.

“If you have the symptoms — the musty smell, the musty feeling — you’re looking for a dehumidifier,” said Chris Koehner, owner of Halo Heating & Cooling. Your air conditioner works like a dehumidifier, but only when it’s on – and even when it’s on, it doesn’t run continuously. “You don’t change [your air conditioner] intermittently, but unfortunately that’s exactly what a conventional heating and cooling system does in your home,” Koehner explained.

Not only can this thick humidity in the air make us unhappy, but it can also cause serious damage to your home if left untreated. Too much moisture can cause doors to stick, create a musty smell in the air, and even lead to mold.

In spaces that don’t have newer air conditioning systems with longer run cycles to extract moisture from the air, a reliable dehumidifier is important. But the range of dehumidifiers can be overwhelming. To help you find the right dehumidifier for your needs, we turned to the experts for buying advice and recommendations.

Best dehumidifiers

Koehner and certified mold inspector Jennifer Nitrio of Mold Help For You agreed that you should rely on reviews when buying a dehumidifier, adding that a good product should have mostly 4-5 star reviews . “Go with a company that has been making this type of product for a long time and has a proven track record,” Nitrio added.

From budget-friendly portable dehumidifiers to elevated units with added conveniences (and costs), here are some of the best dehumidifiers in every category. Unless otherwise noted, all of the dehumidifiers we recommend carry the Energy Star seal of approval, which means the organization has determined that it removes humidity using less energy than a conventional unit of similar size. Our experts said dehumidifiers with the Energy Star seal are the best, but they also recommended a more affordable model as well as a more powerful commercial-grade model without the seal.

Energy Star certified dehumidifiers

hOmeLabs 4,500 Square Foot Energy Star Dehumidifier

Koehner recommended the hOmeLabs dehumidifier for large rooms and for those with high humidity due to its 1.8-gallon water tank and ability to remove up to 50 pints of moisture from the air per day . It also features a sleek design and is one of the quietest models on the market, he said. It has wheels and handles, making it easy to move this 40-pound unit. It also has auto-restart, auto-shutdown, and auto-defrost function.

Danby DoE 50 Pints

The Danby DDR050BLBDB is the newer version of the brand’s older DDR070BDWDB 70-Pint model. Designed for spaces up to 3,000 square feet, the Danby still includes the best casters of any dehumidifier, Nitrio said, which she liked about the older version. “In addition to exceptional portability, the new Danby is one of the most energy efficient dehumidifiers on the market,” she added. It is Energy Star certified to operate economically in even the most humid environments, according to the brand.

Frigidaire Dehumidifier, 50 Pint High Humidity Capacity

Nitrio said she was increasingly impressed with Frigidaire’s line of dehumidifiers. “I would suggest this dehumidifier as a good alternative to the Danby if it’s not in stock,” she said. “It’s easy to clean and it’s a workhorse. It’s really tough in a high humidity area, and it has the continuous drain option. The only caveat, she said, is that it doesn’t have the auto-restart feature.

Tosot 35 Pint Dehumidifier

The Tosot 35 pint dehumidifier is suitable for spaces as large as 3,000 square feet, depending on the brand. It will automatically stop working once the bucket of water fills up or you reach your target temperature, and you can attach a 3/4″ drain hose (not included) to the Tosot so that it drains automatically if you’re not there.. If you’re worried about noise levels or power consumption, don’t be: it has a maximum noise level of just 50 decibels at high speed and it’s Energy-certified. Star You can also find it in 20-quart and 50-quart options.

Other Expert-Recommended Dehumidifiers to Consider

Powerful ergonomic dehumidifier Eva-Dry EDV-1200

Nitrio says Eva-Dry offers a solid product line as well as excellent customer service. Designed for small spaces with the ability to absorb up to 8 ounces of water per day, the EDV-1200 model is optimal for any space up to 1,200 cubic feet, depending on the brand. It features a water fill window as well as an automatic water level switch so you know when the tank is at capacity. This dehumidifier is not Energy Star certified, but it can be a good option if you don’t want to spend hundreds of dollars.

BlueDri BD-BD-130-BL Commercial Industrial Dehumidifier

If you’re looking for a heavy-duty dehumidifier for larger projects, the BlueDri should be your first choice, according to Nitrio. “There is no place where [machine] can’t dehumidify,” she said. “It is also equipped with temperature sensors, automatic water pumps and a high-tech digital panel.” Although this dehumidifier is not Energy Star certified, the brand claims that its efficient rotary compression helps extract up to 225 pints of water per day, compared to the normal 70 pint capacity of typical humidifiers.

What to know about dehumidifiers

Besides personal comfort, people use dehumidifiers for three main reasons, Nitrio explained:

  1. To reduce relative humidity inside to prevent mold
  2. To help reduce indoor pollutantswhat can trigger allergies
  3. To preserve building materials protecting them from moisture and damage (think warped floorboards and rotting support beams)

It is important to understand the wicking effect of humidity. Although the problem may start with dampness in a bathroom, it could also spread to your bedroom and closets. “When you lay a paper towel over a spill, it absorbs the liquid and pulls it into the sheet. It’s a great visual of how humidity works in your home — it doesn’t stay in one room,” Koehner explained.

Before buying a dehumidifier, start by identifying the size and extent of your humidity problems. “Invest $20 in a thermo-hygrometer, which is a digital thermostat that measures temperature and humidity,” Koehner suggested. “The goal is to achieve an average humidity of around 45% in all rooms, all year round.” In addition to helping you identify “problem parts” and how far moisture is spreading, it will also tell you how much fluid you need to remove. Koehner said a smart thermostat can also measure the humidity in your home.

Units that are too small can’t keep up, but units that are too large have a different problem: they cool too quickly, causing them to shut down before dehumidifying enough. You get cold, damp air. This creates a recipe for mold.

It can be tempting to just buy a unit and put it on the highest setting, but that can actually cause more problems. “An incorrect setting can actually lead to mold growth in the dehumidifier, in addition to not removing enough moisture or removing too much moisture from the air,” Nitrio explained. Dehumidifiers are sized by square feet and the number of pints of liquid they remove per day, so knowing the size of the space you’re working with will help you streamline your options.

According to the experts we consulted, a common mistake buyers make is buying the wrong size unit. While some opt for a smaller dehumidifier because it’s cheaper, they quickly learn that they need to invest in a second option to get the job done. There are also those who assume that oversized units will perform better and choose one that is too aggressive.

“Units that are too small can’t keep up, but units that are too big have a different problem: they cool too quickly, causing them to shut down before dehumidifying enough,” Koehner explained. “You have cold, damp air. This creates a recipe for mold.

How to buy a dehumidifier

Some dehumidifiers require much less maintenance than others given their features. “Ideally, buyers should look for a model with a built-in humidistat, which not only measures relative humidity, but also controls it automatically,” Nitrio said. “It takes the guesswork out of whether or not you should turn your dehumidifier on or off.” As well as a handy built-in humidistat, Nitrio recommended looking for other standout features, including:

  • A adjustable thermostat
  • A automatic stop timer Where to restart when needed so you don’t have to constantly check the humidity
  • A defrost mode on a refrigerant dehumidifier, as the coils can freeze at lower temperatures
  • Windows at water level to watch the bucket as it fills
  • Direct install compatibility so you don’t have to manually empty the water that accumulates in the tank of the machine
  • A filter change indicator
  • Handles for easy transport from different rooms

Koehner also warned against any model that isn’t energy efficient, especially if you’re using it all day and night. “Dehumidifiers can increase energy consumption and drive up your electric bill,” he said. “Make sure you choose a dehumidifier with the Energy Star seal of approval.”
