6 Best Dehumidifiers of 2021, According to Experts

Summer kicks in next month, which means temperatures are warming up and homes are starting to start up their air conditioning units, bringing another problem many are still struggling with: humidity. But since we’re trying to get rid of the heat with air conditioning, we’re not necessarily solving the humidity problem. “The problem is that a typical air conditioning system only dehumidifies when it’s on,” says Chris Koehner of Halo Heating & Cooling. “When you get in your car, you usually turn on your air conditioner and leave it on. You don’t turn it off and on again, but unfortunately that’s exactly what a conventional heating and cooling system does in your home. »

Periodic bursts of fresh air do not deal with the rising humidity. And not only can this thick humidity in the air make us unhappy, but it can also seriously damage our skin. From doors sticking and a musty smell to mold and mildew developing, that thick moisture in the air can be a serious problem if left untreated. Besides personal comfort, people use dehumidifiers for three main reasons, says Jennifer Nitrio, certified mold inspector with Mold Help For You.

  1. AT reduce relative humidity indoors to prevent mildew as it thrives in humidity
  2. AT help reduce indoor pollutants which can trigger allergies.
  3. AT preserve building materials protecting them from moisture and damage (think warping floorboards and rotting support beams).

In spaces that don’t have newer air conditioning systems with longer run cycles to extract moisture from the air in addition to cooling, it’s time to turn to a reliable dehumidifier to help. But space for dehumidifiers can be overwhelming. How should you go about finding the best dehumidifier for you and where should you look? To help you prepare and buy the right dehumidifier, we’ve got expert shopping tips and recommendations.

Best dehumidifiers

From budget-friendly portable dehumidifiers to elevated units with added conveniences (and costs), here are some of the best dehumidifiers in every category to meet different needs and help you find the one that’s right for you.

Best all-in-one dehumidifier: hOmeLabs

With a 1.8 gallon water tank, this relatively affordable dehumidifier removes up to 50 pints of moisture from the air per day. “It’s pretty quiet for its size and the 50 pint dehumidifier is actually known to be the quietest model on the market. Other outstanding features are that it is easy to move around, the electronic display is easy to use and the water tank is very easy to use,” explains Nitrio. “And it has auto restart, auto shut off, and auto defrost function.”

Best Basic Dehumidifier: Pro Breeze

Designed for small spaces, this “quiet” dehumidifier can hold up to 52 ounces of water. “It’s just amazing because of the small size of the device,” says Nitrio. “It’s portable and lightweight with an auto-shutoff feature. While it doesn’t have a lot of bells and whistles, it’s a workhorse in small spaces with only minor humidity issues.

Best portable dehumidifier: Danby

This Danby dehumidifier is the newer version of the brand’s older DDR070BDWDB 70 pint model. It still includes the best casters of any dehumidifier, which made the old Nitrio version the top choice for portable dehumidifiers. “In addition to exceptional portability, it’s also one of the most energy-efficient dehumidifiers on the market,” she said of the older model. This unit works in spaces over 3,000 square feet.

Best Heavy Duty Dehumidifier: BlueDri

If you’re looking for a heavy-duty dehumidifier that’s worth the investment, then the BlueDri should be your first choice, according to James. “With a massive 225 pint capacity, there isn’t a place this can’t dehumidify,” he says. “It is also equipped with temperature sensors, automatic water pumps and a high-tech digital panel.”

Other dehumidifiers to consider

Besides the dehumidifiers recommended by the experts above, here are some other popular options.

This Alrocket option is a best seller on Amazon. Weighing 2.9 pounds, this mini dehumidifier is easily portable. It can hold up to 35 ounces of water for use in rooms as large as 260 square feet. In addition, it is silent and has an automatic shut-off. Over 11,200 reviews on Amazon left it with an average rating of 4.4 stars.

The Tosot 35 Pint Dehumidifier is suitable for spaces as large as 3,000 square feet. It will automatically stop working once the bucket of water fills up, as well as once you reach your target temperature. Plus, it has a continuous or automatic drainage system for added convenience (hose not included). And it’s quiet and Energy-Star certified. You can also find it in a 20 and 50 pint option. Over 3,600 reviews on Amazon left it with an average rating of 4.6 stars.

Before buying a dehumidifier

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

That’s why, before buying a dehumidifier, first identify the size and extent of your humidity problems. “Invest $20 in a thermo-hygrometer, which is a digital thermostat that measures temperature and humidity,” suggests Koehner. “The goal is to achieve an average humidity of around 45% in all rooms, throughout the year.” In addition to helping you identify “problem rooms” and how far they have spread, it will also tell you how much fluid you need to eliminate.

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. You get cold, damp air. This creates a recipe for mold.

“Don’t guess the humidity level in your home or bedroom. Human perception should never govern dehumidifier settings,” advises Nitrio. “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.” Dehumidifiers are also sized in square feet and the number of pints of liquid they remove per day. Therefore, knowing the size of the space you are working in 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.

Then there are those who assume that oversized units will perform better and choose one that is too aggressive. “Undersized units can’t keep up, but undersized units have a different problem,” says Koehner. “They cool too quickly, causing them to shut off before they dehumidify enough. You get cold, damp air. That 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,” says Nitrio. “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 recommends looking for other standout features:

  • A adjustable thermostat
  • A automatic stop timer Where light up 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 warns against any model that is not energy efficient, especially if you use it all day and night. “Dehumidifiers can increase energy consumption and drive up your electric bill,” he says. “Make sure you choose a dehumidifier with the Energy Star seal of approval.”
