Keeping your home’s humidity under control is about more than comfort—it can help keep you healthy by staving off mold, mildew, and the problems they can cause, such as allergic reactions and respiratory issues. That’s where dehumidifiers come in. Unsure whether you need one? Check for excess condensation, musty smells and other tell-tale signs before buying.
The main things you need to consider when choosing a humidifier are how large your home is and how damp the air is. The most common... dehumidifier capacities are 30, 50 and 70 pints, which refers to how much water the unit can remove from the air in 24 hours. Even 30-pint units are often suitable for moderately damp spaces up to 2,500 square feet, but wet or extremely wet spaces of that size will be better served by a 50-pint unit, according to the Association of Home Appliance Manufacturers. Larger 70-pint units are better for bigger homes or spaces.
One particular feature to watch for is whether a dehumidifier allows continuous draining, which means you won’t have to constantly empty the unit’s water tank. Some will come with a hose that allows this, while others will require one separately.
Whatever your needs, here are the best dehumidifiers that should be equal to the task.
If you need a large capacity dehumidifier that handles 70-pints per day in moisture this pick from Frigidaire is a winner. Use it in your basement, attic or anywhere dampness lurks. In order for it to handle this large capacity, it is best to have it by a drain so it can properly dispose of the water when it needs to or you have to dump this every 12 to 24 hours.
Users love that it is quiet and that it pulls a lot of moisture out of the air keeping it at their optimal percent of humidity. For anyone that needs heavy-duty dehumidifiing, this is a smart option.
For most people, a 30-pint humidifier will do the job well. Unless you are living in super swampy conditions and have a large, multilevel house, you won't necessarily need a huge machine. This model from Frigidaire will dehumidify up to roughly 1,500 square feet, so most people will be covered.
The unit will shut off automatically when the water tank is almost full — no worrying about it overfilling and malfunctioning – and it also has an alert so that you can empty the tank before that happens. Don’t want to worry about that at all? There’s a continuous draining option, too. It is low-temperature optimized and will do just fine down to 41 degrees, making it ideal for a frigid basement or another space that might not be fully heated.
The tank is easy to empty, and casters and top and side handles make it easy to move around your home or apartment. And the six-foot cord and optional hose make it easy to position and empty in your home. Reviews have been mostly positive, though there are some durability complaints with some users reporting error codes.
For anyone who wants a bit more powerful dehumidifier, consider this one from Friedrich. The Energy-Star rated appliance has all the standard features of a dehumidifier, along with a built-in pump that means you won't have to drain the tank yourself. Instead there's a 15-foot hose that will pump out and drain the water continuously. This is an important feature if you live somewhere that you need to leave your dehumidifier running for an extended period of time.
You can set your desired humidity level—anywhere from 30 percent to 90 percent—and this model will work in temperatures as low as 41 degrees Fahrenheit.
A few reviewers have complained of noise problems or that the condenser and temperature sensor are too close together, but other than that, most buyers have been satisfied.
Capacity is the main thing that differentiates dehumidifiers, but the Black and Decker BDT70PWT Portable Dehumidifier boasts a feature that sets it apart from most other models: An internal pump that can push water out, even when the included draining hose must be placed vertically. It also has a 70-pint capacity that means it can dry out the largest spaces.
The BDT70PWT has three fan speeds, one more than many dehumidifiers, as well as an all-electronic control panel with separate modes for bedrooms, living spaces, and basements. There are full-bucket and filter alerts, castors to make moving the unit easier, and an included hose for continuous draining. Most reviewers say it’s fairly quiet, especially for a larger dehumidifier, and rave that it does an effective job in even very damp spaces.Continue to 5 of 7 below.
Buyers fighting excess moisture in smaller spaces don’t need to overspend. Reviewers say the Eva-Dry Electric Petite Dehumidifier does an admirable job reducing humidity in laundry rooms, bathrooms, and even RVs. Though this unit holds only a pint of water at a time, users like how compact it is and don’t mind emptying the tank frequently.
At its low price, the Eva-Dry doesn’t boast a lot of extra features. It has a simple on-off button, a full-tank indicator and an automatic shutoff. And thanks to its small size, it can sit on a counter or in the most storage-challenged corner. Most reviewers say noise from the unit’s small fan is negligible, but warn that it’s underpowered for any damp space larger than a small bedroom. Others wish this dehumidifier could continuously drain itself since the small tank may fill up fast.
Sometimes the need for a big unit doesn't make sense, say in a bedroom, closet or another small part of the home. When that is the case a mini dehumidifier like this one from Eva-dry will take out moisture and alert you when it is time to replace the cartridge. This unit works in areas 33 square feet or smaller and it takes about 20-30 days to replace the filter. It doesn't even need batteries or needs to be plugged in. Just place in the room that has moisture and it will alert you when it is time to swap out the crystals.
Not in the market to buy a dehumidifier? Then DampRid Moisture Absorbers are a smart and budget-friendly option that will soak up moisture in places like your crawl space, basement and beyond without the need for electricity. All you need to do to activate is take off the lid, the bucket still has a plastic top to prevent spills from occurring. When all the crystals are absorbed and the bucket is full of liquid it's time for a refill.
Customer's love that this will absorb moisture quickly from floods and more. And they're impressed with how well it takes musty smells out of the air. Besides your home users use this in boats and RVs to help dry them out.
