Best Dehumidifier Buying Guide for 2022

Best Dehumidifier Buying Guide for 2022

With the heatwave on blast, the best dehumidifier will quickly reduce any residual moisture effectively, which is often the case if your home has humidity. The best dehumidifiers will prevent a build-up of mold, mildew and, water stains over time. More importantly, dehumidifiers and the best vacuum cleaners will improve overall air quality, particularly for allergy sufferers.

Unfortunately, that stickiness doesn’t always stay outside when it’s humid. It can creep into your home and make already wet spaces like the bathroom and laundry room even damper. For most, a home between 30% to 50% humidity is ideal (higher in the summer and lower in the winter). When humidity creeps above 50%, the space can become a breeding ground for mold, mildew, dust mites and, other critters.

That’s where a dehumidifier comes in. Unlike a humidifier, which adds moisture to the air, a dehumidifier removes excess water from your environment, preventing mold, mildew and, other issues that can harm your health — or 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 the reservoir. Dry air is then propelled back into the room.

What’s more, the best dehumidifiers will also rid our homes of musty odors, and make handy appliances for drying freshly-washed laundry quickly. But with so many different types of dehumidifier available, it can be challenging to know which one is right for your home. First, consider the size of the room you need it for as this will affect the output. There are models suited for smaller rooms, and others for large spaces. Also, what is your budget? A mini one could start from as little as $200 right up to $2,000 upwards.

Best Dehumidifier Buying Guide for 2022:Our choice

1.Frigidaire Dehumidifier

View on Amazon

This dehumidifier came out on top because it has simple, helpful features. A digital read-out helps you monitor the current humidity, and the circular window shows you when the bucket needs a change (you can also connect a hose for continuous drainage). The cord wraps around hooks on the back for easy storage, and the side handles and wheels make it a breeze to move around.

2.Midea 1,500 Sq. Ft

View on Amazon

This Midea dehumidifier is suitable for spaces up to 1,500 square feet, but if you’re following Mansfield’s advice, get this for a space that’s 750-square-feet or smaller. It got five stars from more than 7,000 reviewers, many of whom were impressed by how much moisture it can pull out of the air. “1.6 freaking gallons of water … in only 12 hours!” one reviewer writes. When the tank is full, the dehumidifier automatically shuts off and restarts when the tank is emptied. If you’d rather not have to empty the tank multiple times a day, you could attach a hose for continuous draining. Having a machine that runs constantly sounds expensive, but the Midea is Energy Star certified, and one reviewer says it “doesn’t run up the bills as far as we can tell.”

One regular piece of maintenance that’s required is cleaning the filter, but reviewers appreciate that the filter is washable and that there’s an indicator that turns on when it needs to be cleaned. Cleaning the basin that collects the water is also important. “Any sort of moisture in the device is going to cause mold growth and stimulate dust mite growth, and what happens is those spores could potentially cycle back into the air,” says Tharpe. “Dehumidifiers are essentially going to pull air in and dry it over cold contractions and circulate things, and we don’t want mold to grow.”

3.Frigidaire Dehumidifier

View on Amazon

There aren’t many smart dehumidifiers available, but we’ve come to believe that the ability to monitor and control them remotely is a real plus. Dehumidifiers often need to have their collection tanks manually drained, and they’re also often used in an out-of-the-way corner of a home, like a storage cellar.

Knowing from afar when the tank is full (and simply knowing whether the machine is operating as it should) can save you from extra trips to check on things. For that reason, the Frigidaire Gallery FGAC5044W1 is our top pick among dehumidifiers. Its Wi-Fi connectivity lets you monitor and control it via Frigidaire’s app (iOS and Android), and it can also be synced with Amazon Alexa and Google Home for voice control.

The app is easy to set up, we found its alerts accurate, and we were able to cycle the machine through its settings with a touch of the screen. It’s suitable for spaces of up to about 1,200 square feet, and it’s Energy Star rated. We wish it had a pump, which eliminates the need for manual drainage, but if you can place it near a drain, the Gallery (like all dehumidifiers) can be set to drain itself passively via a length of hose.

4.GE Energy Star Portable Dehumidifier 50 Pint

View on Amazon

The GE APER50LZ is a close second to the Frigidaire FFAP7033T1. It’s the only other dehumidifier on our list with an active water pump, although you also have the option to passively drain the tank using a hose or by carrying the bucket to a sink.

This device comes with all the features you’d expect in a top-ranked dehumidifier, including a digital display for indicator lights and changing timer, speed and humidity settings.

On performance and noise levels, the GE APER50LZ is right in line with the Frigidaire. The biggest difference is in design: There’s no option for wrapping or storing the power cord, and the handles may be difficult to grab. Setting up the passive drain is also not terribly convenient.

That said, the GE APER50LZ is an equal alternative to the Frigidaire FFAP7033T1 if you can find it at a better price.

5.Honeywell Smart WiFi Energy Star Dehumidifier

View on Amazon

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.

6.GE Energy Star Portable Dehumidifier 50 Pint with Pump

View on Amazon

If draining via a hose isn’t an option, this model from GE has a built-in pump so you can drain out a window or into an elevated sink. Since it can remove moisture in a space up to 1,500 square feet in size, this durable pick is ideal for use in basements or in small homes requiring more widespread dehumidification. If you choose not to use the hose, it has a full tank alert — and if you can’t empty it in time, it will automatically turn off to avoid overflow.

How we test dehumidifiers

The Good Housekeeping Institute regularly tests home appliances including dehumidifiers. When we test dehumidifiers, we choose 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, 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.

What do the new testing standards mean for my shopping?

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 with newer units apples to apples.

What to consider when buying a dehumidifier

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 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.

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.

How to make your dehumidifier last longer

1. Humidity maintenance method

The operation of the dehumidifier should pay attention to carefully adjusting the humidity to avoid overheating or overcooling. If the heating temperature is lower than 2 ℃, the electricity can save about 10%. Open doors and windows as little as possible while the dehumidifier is running. Frequent opening and closing of doors and windows will reduce the cooling and dehumidifying effect of the dehumidifier and cause extravagant electricity. Especially in summer, blocking the direct sunlight can make the dehumidifier save about 5% of electricity. In addition, the space with a good sealing premise saves the most electricity.

2. Switch maintenance method

When the dehumidifier is used, do not switch it on and off frequently. It is best to control the on and off of the switch through the dehumidifier controller and turn off the power when not in use. When there is a sudden power failure during operation, although the dehumidifier can be turned on immediately, it will take 3 minutes to run, so it is best to turn it on after three minutes. Pay particular attention to the effective use of the timer function. When sleeping or going out, use the timer function to make it run only for the necessary time to save power.

3. Component maintenance method

In the daily dehumidifier operation, pay attention to protecting the fins of the condenser and evaporator. The cooling fins of the condenser and the evaporator are made of 0.112 mm aluminum sheets inserted into copper tubes and then expanded, which cannot withstand collisions. If the cooling fins are damaged, it will affect the heat dissipation effect of the dehumidifier and reduce the dehumidification efficiency. Also, protect the refrigeration system. If the components of the refrigeration system or the connecting pipes are damaged, the refrigerant will leak, and the dehumidifier will not be able to cool. Remove the movement annually, and inject appropriate lubricating oil into the fan motor bearing. The refrigeration system does not need to be dealt with as long as the surface dirt is removed. Also, the dehumidifier should accurately select the fuse (fuse). Select the specification of the fuse wire according to the rated current indicated on the product copy.

4. Air outlet maintenance method

Do not cover the air outlet of the dehumidifier. When using the clothes drying function, keep the clothes at a certain distance from the air outlet of the dehumidifier. When items are placed at the air outlet of the dehumidifier, the air circulation system will be blocked, which will seriously damage the life of the household dehumidifier.

What types of dehumidifiers are there?

1. Cooling dehumidifier

According to the function of use, it can be divided into general type, cooling type, temperature regulating type, and multi-functional type. There are many types of cooling dehumidifiers, such as whether there are fans, they can be divided into conventional dehumidifiers, duct type dehumidifiers. According to the applicable temperature range, it can be divided into A-type (normal type 18~38℃), and B-type (low-temperature type 5~38℃). According to the air supply and return air*, it can be divided into the front return and front supply with hood type, rear return, top supply type, etc.

2. Rotary dehumidifier

The main structure of the rotary dehumidifier is a continuously rotating honeycomb drying wheel. The drying wheel is the key component for absorbing moisture in the dehumidifier. It is composed of a corrugated medium made of special composite heat-resistant materials. A hygroscopic agent is carried in the corrugated medium. This design has a compact structure and can provide a huge surface area for the humid air and the hygroscopic medium to full contact, thereby greatly improving the dehumidification efficiency of the dehumidifier.

3. Solution dehumidifier

The solution dehumidification air conditioning system is a new type of air conditioning product developed based on the active dehumidification air treatment technology that uses dehumidification solution as a hygroscopic agent to adjust air humidity and water as a refrigerant to adjust air temperature. Using the physical properties of the dehumidifier, through innovative solution dehumidification and regeneration method can achieve high-efficiency dehumidification above the dew point temperature. It has the technical characteristics of simple manufacture, reliable operation, energy saving, and high efficiency.

The duct dehumidifier uses an evaporator to cool and dehumidify the air and recover the condensation heat of the system to make up for the heat lost in the air due to cooling and dehumidification. The utility model relates to a pipeline-type temperature and humidity adjustment method and its equipment for heating, cooling, and dehumidifying indoors at low temperatures to meet the requirements of indoor temperature and humidity.

Is the water from the dehumidifier safe to drink?

No

“Under normal circumstances, the dehumidifier’s water cannot be drunk. Otherwise, it may endanger the drinker’s health. The specific analysis is as follows: the dehumidifier’s water is the dehumidifier in the normal use process; after the moisture in the air has been processed, It is formed by condensation and storage. This water contains various impurities or bacteria, which cannot meet the drinking standard. Therefore, drinkers usually cannot drink water from dehumidifiers. Otherwise, multiple bacteria may invade the body and endanger health, causing diarrhea, abdominal pain, etc. Drinkers can use the water from the dehumidifier to water flowers or flush the toilet.

Can a dehumidifier cool a room?

No

“Dehumidifiers can’t cool a room; on the contrary, the dehumidifier mode of an air conditioner can cool it down.

What does a dehumidifier do?

1. Dehumidification

The primary function of the dehumidifier is to dehumidify, which is to treat the water molecules in the air and then discharge the dry air out of the machine so that the indoor humidity can be kept at a suitable relative humidity and the indoor humidity can be improved.

2. Dry clothes

Clothes are not easy to dry in wet weather, but the dehumidifier can quickly dry the clothes. Turn on the dehumidifier in damp weather, and the clothes can dry overnight, which makes the whole spring beautiful.

3. Reduce bacterial growth

The dehumidifier reduces the humidity of the air, thereby reducing the growth of bacteria. The environment with high humidity is a breeding ground for various bacteria to multiply rapidly. If the humidity is below 60%, bacteria and harmful microorganisms will be significantly reduced.

4. Protect household items

In addition to reducing air humidity, dehumidifiers can effectively prevent furniture items, home appliances, luxury goods, food, etc., from being damaged by moisture regain. After the dehumidifier reduces the humidity, it indirectly protects these household items from moisture hazards.

5. Reduce the incidence of disease

When the humidity of the air is reduced, it is not easy for bacteria to multiply, the moisture is not significant, and the human body will be in a relatively relaxed state, which can reduce the occurrence of rheumatism, arthritis, neuralgia, bronchitis, asthma, and other diseases.
