The best dehumidifiers in 2024

The best dehumidifiers are essential if you have excess humidity in your home, will help to get rid of condensation and prevent mold. This is especially the case during colder months when we can't open up our windows for long periods to allow ventilation. In addition, while not as effective as the best air purifiers, dehumidifiers can help eliminate bad smells and reducing dust and airborne allergens. 

But with so many types of dehumidifier on the market, it can often be tricky to know which one is right for your needs. Before buying, there are some things to consider first. For instance, what coverage do you need for your home? If you have a particularly large or humid room, you may benefit from a machine with a higher capacity and a pump, to make disposing of the water easier. Also, if you have several rooms that need a dehumidifier, it may be worth buying a smaller, more portable unit or on wheels. 

To help you decide, we've tested the best dehumidifiers to suit every space and lifestyle.

New EPA classification standards went into effect in mid-2019, as detailed at the end of this page. We've indicated when a model is classified under the older set of standards.

Pump installation might be tricky

The Frigidaire FFAP5033W1 is the best dehumidifier overall, based on reviews of its nearly identical predecessor, the Frigidaire FFAP7033T1. 

It's one of the few devices on our list with an active pump, meaning you can send water to an elevated sink or out a window if you don't have a floor drain and don't want to go through the hassle of removing and emptying the bucket. 

What bumped the Frigidaire FFAP5033W1 above the other devices we considered is its design. It's sleek and has an attractive digital display, making it easy to see indicator lights and settings.

There are hooks for wrapping up the power cord when the machine sits right next to an outlet or when you want to store it away, and the filter is easily accessible for removal and cleaning. While the device does come on casters for easy rolling, it also has a heavy-duty top handle for carrying down stairs.

One of the few areas in which the older model, the Frigidaire FFAP7033T1, fells short was in the initial pump setup. Testers and device owners reported that removing the plug from the pump socket was tricky, and that in some cases the plug simply broke off. 

This flaw isn't unique to Frigidaire, but it is something to prepare for if you're purchasing this model for the convenience of having a pump. We'll keep an eye out to see if the FFAP5033W1 suffers from the same problem. 

While the pump option does come at a premium, it's a nice feature to have. Of course, you can also default to continuous draining (if you have a floor drain) or to simply dumping out the bucket manually if you'd prefer.

In the switch from the FFAP7033T1 to the FFAP5033W1, Frigidaire increased the tank capacity from 13.1 pints to 16.9 pints. If you live in a really damp space and run the machine continuously, that's a significant improvement, because water volume will fill up pretty fast, and the device will shut down until you empty the bucket. The GE APER50LZ, our runner-up, has a 15-pint capacity.

As with many of the older models that fell under the previous set of Department of Energy regulations (see below), the FFAP7033T1 is disappearing from store shelves, so you'll have an easier time finding the Frigidiare FFAP5033W1 or its pump-less sibling, the FFAD5033W1.

App lacks two-factor authentication 

We loved testing the Midea 20 smart dehumidifier. Once connected to its app, you can monitor it from your phone, including viewing the humidity levels and receiving alerts when the bucket is full. You can change the settings remotely too, adjusting the speed of the fan with three levels to choose from. 

Voice control is available via Alexa or Google Assistant, although two-factor authentication is missing. It stands out for storage though, as this dehumidifier can be ‘nested’ into itself, taking up half of the space.  

In terms of performance, it gets the job done and proved to be a useful asset for us when dealing with a flooded basement. It’s also incredibly easy to empty, thanks to the lower half turning into a bucket and handle. 

Despite the name, it can hold about 24 pints, although this is still relatively small compared to others on our list. Ultimately, this dehumidifier has a very user-friendly design which couldn't be more compact to store.

Reasons to avoid

-
Small tank requires frequent emptying (if not using hose to continuously drain)

The Honeywell TP50AWKN, which replaces the virtually identical Honeywell TP50WK but adds Wi-Fi connectivity, is well regarded by professionals and customers alike. 

If something does go wrong with the TP50AWKN, you're covered under Honeywell's five-year warranty. Most of the dehumidifiers we considered come with one-year or two-year warranties, so this extended policy ensures that your investment is protected.

One downside: The Honeywell TP50AWKN's water bucket holds just 7 pints (three-quarters of a gallon), a small fraction of what the machine can condense in a day. If you don't have the option to continuously drain, you'll find yourself emptying the water bucket more frequently with the Honeywell TP50AWKN or going without dehumidification once the tank reaches capacity.

Many buyers reported trouble using app

You probably don't need a Wi-Fi-enabled dehumidifier, but if smart-home devices are your jam, then the 50-pint Frigidaire FGAC5044W1 may deliver on what you're looking for. 

You'll receive push notifications when the water bucket is full, and you'll be able to remotely control the fan speed, target humidity and power. You can also set up voice controls for the Frigidaire FGAC5044W1 with Amazon Alexa and Google Assistant

All these smart features can be especially handy if you're out of town or you're monitoring a dehumidifier in a rental property. However, many online purchasers of the unit reported trouble setting up the app, which gets mostly negative reviews on both Google Play and the App Store. Here's hoping Frigidaire gets that sorted out.

This dehumidifier is fairly similar to our top pick, the Frigidaire FFAP5033W1, but swaps Wi-Fi for a powered water pump. A drain hose comes with the unit to let the tank drain passively, or you can dump out the 2-gallon bucket by hand. 

There's also a washable dust filter and an ionizer to eliminate airborne particles.. A light at the top of the front face changes color to let you know system status.

Hundreds of Amazon, Wayfair and Walmart customer reviewers liked the Frigidaire FGAC5044W1 a lot (even if many of them didn't like its mobile app), rating the unit at  4.4 out of 5 stars on average.

(Note: This replaces an older model, the Frigidaire FGAC7044U1, which has been discontinued.)

How we picked

To determine the best dehumidifiers on the market, we looked at the top picks from Wirecutter, Consumer Reports, the Good Housekeeping Institute, Dehumidifier Buyers' Guide and others, as well as top-selling and highly reviewed machines on Amazon, Best Buy and The Home Depot. 

We narrowed the list down to several models based on features, price, efficiency and ease of use.

How to choose the best dehumidifier

There are a huge range of dehumidifiers on the market. Before choosing your favorite, here are a few factors you should consider: 

Type

There are different types of dehumidifiers on the market. The most common type is a condensing dehumidifier, which pulls the absorbed air over refrigerated coils, which cools it enough the condense and separate the moisture. 

Other types include desiccant dehumidifiers, which will use a water-absorbing material, and thermoelectric dehumidifiers, which operate with charged plates. Generally speaking, neither of these latter two types are as effective as condenser models, which is why we only recommend this type in our list. 

Capacity

Dehumidifiers generally come in three sizes: large (45-50-pint capacity), medium (30-pint capacity) and small (20-22-pint capacity). 

Under the old regulations, these sizes were 70, 50 and 30 pints, respectively, and you'll see such numbers with three older models above.

Noise level 

If you’ll be placing a dehumidifier in a quiet room, such as a bedroom or home office, where you need to fall asleep or concentrate without being disturbed, consider the noise level of the dehumidifier before you buy. Aim for a dehumidifier with a decibel level of around 50 decibels or below, anything above this level will be louder.

Features to look out for

Pint capacity   — The capacity in pints relates to how much moisture the dehumidifier claims to absorb per day. The bigger the capacity, the larger and damper space it can handle.  

Bucket size  — Pint capacity shouldn’t be confused with bucket size however. This specification indicates how much the internal bucket can actually hold before it will need to be emptied. The larger the bucket, the less often you will need to empty it.  

Drainage type  —  On this list you will find passive and pump drainage types. Passive types let you passively drain the water through a hose, or alternatively you can manually carry and empty the bucket yourself. Whereas pump drainage types will automatically pump the water out. Pumps are preferred as the water doesn’t need to rely on gravity alone to drain, so you can direct the hose into a sink or out of the window. However, these models do cost more than without. 

Energy Star Certification  —  It’s always useful to look out for Energy Star Certification as this guarantees savings in terms of energy and money. 

Humidity sensor  — With a humidity sensor, your dehumidifier will detect relevant changes in the atmosphere and can automatically switch on and, in some cases, set its power accordingly. Those without a sensor will just be manually controlled.  

Frost sensor  —  A frost sensor will detect the formation of ice on the condenser coils. The dehumidifier will then shut off the compressor to give the ice a chance to melt. If it continues to run with frost on the coils, this can damage the parts and make the appliance work much harder to absorb any moisture. 

Auto restart  —  If the dehumidifier suddenly loses power, auto restart means it will automatically switch back on to its previous settings once power is restored. 

Number of speeds —  This relates to how many speeds the fan has on the dehumidifier. The more speeds there are, the better as it gives you greater control and means excess energy isn’t wasted.

Where is the best place to put a dehumidifier?

Ideally, a dehumidifier should be placed in the centre of a room to work efficiently. This allows the air to circulate properly around the unit. 

Generally, a dehumidifier can dry out a room between 24 and 72 hours. But this depends on whether the room is large or has high humidity levels, which would take up to weeks to dry out. 

How to clean a dehumidifier

When you consider that bacteria and mold is being sucked into your humidifier, it’s no wonder that it needs an occasional clean. This isn’t as difficult as you might think, simply follow these steps if none are given in your manual:

1. Unplug the humidifier from the wall. You don’t want to risk an electric shock! 

2. Remove the water reservoir bucket and tip out any residual water. Clean this with warm soapy water and a microfiber cloth.

3. While that’s drying, wash the filters. The filters collect any impurities so it’s essential that these get an occasional clean. You should have a main filter and potentially a much smaller bucket filter. If you’re not sure where to find these you can refer to your manual. Both need to be washed in warm soapy water, rinsed and then left to dry.   

4. If you notice a lot of dust inside your machine, you can also use a vacuum cleaner with a brush attachment to pick up any remaining fluff. 

5. Lastly, give the outside a once over with a microfiber cloth for finishing touches.   

Do dehumidifiers help to cool the air?

Dehumidifiers remove moisture from the air and can make a room feel less humid. However, they don’t cool the temperature of the air —  although the effect of the reduction in the moisture level can make it feel as though it’s cooler. In fact, a dehumidifier will produce heat while it’s working, which may slightly increase the room temperature.

Is it better to oversize your dehumidifier?

In some cases, there can be advantages for buying a larger dehumidifier. Experts suggest to run it on a lower setting, and this will being down your  electricity usage and energy bills. 

What's more, if a dehumidifier is run on a lower setting, this also means a lower noise level, which is ideal for bedrooms.
