We updated this article in November 2022 to ensure the information reflected current prices, features and more. Our top picks, based on testing notes from the Good Housekeeping Institute, remain the same.

Humid, sticky air doesn't always stay outside. It can creep into your home and make already wet spaces, like bathrooms and basements, even more damp. For most of us, keeping the air in our home between 30% and 50% humidity is ideal (higher in the summer, lower in the winter). But when humidity creeps above 50%, the rooms in your home can become a breeding ground for black mold, mildew, dust mites and other critters.

That's where a dehumidifier can help. Unlike a humidifier, which adds moisture to the air, the purpose of a dehumidifier is to remove excess water, helping to prevent black mold, mildew and other issues that can harm your health and your home. Most dehumidifiers draw humid air in through an inlet using an internal compressor and fan. The air goes through cool coils that pull out excess moisture and condense it into a reservoir, which you must regularly empty. Dry air is then propelled back into the room. That dry air can feel hot on its way out of the dehumidifier, so most people position their unit in a spot that's out of the way of their daily routines.

Over this past year, our product analysts in the Good Housekeeping Institute Media & Tech Lab have tested a dozen of the leading-brand condensing dehumidifiers for performance, noisiness and efficiency. We grade ease of use, including portability, operation, controls and emptying of the reservoir bucket. Our top picks for the best humidifiers are based on comprehensive testing and our industry expertise within this category for reviewing specifications and documentation.

      How we test dehumidifiers

      The Good Housekeeping Institute regularly tests home appliances, including dehumidifiers. In fact, we've tested a dozen dehumidifiers in the past year alone.

      When we test dehumidifiers, we review only condensing models, since they remove far greater quantities of moisture from the air than desiccant models (which use a water-absorbing material) or thermoelectric dehumidifiers (which use an electric charge to "attract" humidity).

      In our evaluations, which take places in our Labs and in our testers' homes, we rate features, noise level and efficiency of operation. We also look at ease of use, including portability, operation, controls and the removal and emptying of the bucket.

      A note on the DOE's new testing standards

      In 2019, the Department of Energy (DOE) changed the parameters of measuring the capacity of dehumidifiers. In the past, dehumidifiers were officially tested at 80°F but since June 13, 2019, dehumidifiers are required to be tested at a lower temperature, 65°F, "to more accurately reflect expected performance in a basement setting."

      This means that a dehumidifier tested in accordance with the new protocols will likely report a smaller capacity. For example, a previously labeled "70-pint dehumidifier" will now likely be considered a 50-pint dehumidifier under new guidelines. In this round up, all of the picks are reflective of these new standards. This means that if you previously purchased a dehumidifier, the original pint size may have been adjusted according to new guidelines as you cannot compare older units directly against newer units.

      What to consider when buying a dehumidifier

      ✔️ Price point: If you are asking yourself if a dehumidifier is worth the price, it most likely it is. The fact that you are looking up what to purchase shows that you are already dealing with excessive humidity. Dehumidifiers are not simple devices. While some have tanks and some have pumps, both remove moisture from the air and put it somewhere else. The more efficient, the more powerful, the more you need to run it, the more expensive it will be. When it comes to dehumidifiers, it's a guarantee you'll be happier having one versus not having one, no matter the price point.

      ✔️ Type: If humidity is a problem throughout the entire house, an integrated whole-home system may be the way to go. If your moisture issues are more seasonal or confined to only some rooms of the house, a portable residential unit is your best bet. Smaller dehumidifiers tend to cost less and can be easier to move, but they can be less efficient when running at a constant rate. It's best to err on the side of caution by buying a larger unit than a smaller one and having the unit run less frequently.

      ✔️ Size: The size of your room and how damp it is will determine how big or small your dehumidifier should be. Dehumidifiers are sized based upon how many pints of moisture they can remove in a day: The larger and wetter your space is, the more powerful your unit will need to be. For example, a 70-pint dehumidifier can cover a very damp 700 square feet or a slightly damp 1,200 square feet. Keep in mind: If the room is cooler (say, a basement), the dehumidifier will remove less moisture since colder air contains less moisture than warmer air. Here's a quick guide:

      • Small: Removes 20 to 25 pints of moisture at 65°F, or 30 to 40 pints at 80°F (about 400 to 600+ square feet)

      • Medium: Removes 30 to 35 pints of moisture at 65°F, or 50 to 60 pints at 80°F (about 800 to 1,000+ square feet)

      • Large: Removes 40 to 55 pints of moisture at 65°F, or 70 to 90 pints at 80°F (about 1,200 to 1,500+ square feet)

        ✔️ Features: There are a ton of features to consider when it comes to dehumidifiers, but these are the ones our pros recommend keeping in mind:

        Hose connection: If you'll be using a large-capacity dehumidifier for a particularly wet job, finding a dehumidifier with a hose connection can save you from having to empty the machine manually.

        • Pumps: If you can't find a model with a hose, look for one that has a pump to send water up to a sink or window. Otherwise, you'll have to physically (and frequently) dump the captured water.

        • A filter indicator: reminds you when to clean your air filter.

        • An auto-humidistat: can sense the moisture in the air and turn off automatically once the desired level is reached.

        • Low temperature setting and/or auto-defrost: is helpful if the dehumidifier will be in a cool place, since it ensures the unit can properly operate in cooler temps.

          How do I make sure my dehumidifier runs efficiently?

          ✔️ Make sure airflow isn’t restricted. Some units have vents on top, allowing it to sit against a wall. Others have vents on the sides which means they shouldn't be pushed up against walls or furniture.

          ✔️ Regularly clean the air filter. The dehumidifier won't work as well if it's dirty. Make sure you're tending to it at least once a week.

          ✔️ Be sure to unplug the machine whenever you're emptying the container or cleaning it.
