Best Dehumidifiers Reviewed & Rated for Quality

last updated: Feb 06, 2019

Most individuals will spend most of their summer days outdoors in the heat. However, when it is time to go into their home, the majority of people would expect the opposite in terms of weather from what they longed for outside. Humidity can be a dangerous word when it comes to your home.

Without humidity control, items inside the home, as well as the actual house itself, can absorb moisture from the humidity and cause damage to the item.  The best way to prevent this damage is to remove the extra moisture from the air which is why you need a dehumidifier. A dehumidifier is a machine that either absorbs or condenses moisture in order to remove it from the air. With that in mind, we offer our top 10 dehumidifiers.

Criteria Used for Evaluation

Capacity

Capacity

Dehumidifiers are measured in the amount of water they can remove in a day. Larger capacity means that the unit is capable of removing more water from the air and can control the humidity in a larger area as well. You will need to match the capacity to your needs because an undersized unit will not be able to control the humidity properly if the area is too large. While it is possible to use a large unit in a small area, you are going to be overspending for capacity that you do not need.

Large capacity units are defined as units that remove over 75 pints of moisture in a day. These units are best used in large spaces or spaces that are wet. If you find that the space is extra large or extremely wet, then you should get the largest capacity that you can manage and you may need to get more than one unit.

A medium capacity unit is a unit that removes between 45 to 50 pints of water in a day. These are well suited to use in medium-sized spaces or in large spaces that are only slightly damp. Most of the time, these units will cost less than a large capacity unit but this isn't always the case. Finally, there are the small units pull under 40 pints of moisture in a day. While they cost the least out of all of the models, they only are suitable for small areas that are damp. Most people tend to use these for a single room or a bathroom since they have a small capacity. When you are picking out a dehumidifier, you will need to make sure that it is properly sized for your needs.

Power Source

Power Requirements

Almost all, but not quite all, dehumidifiers need a source of energy in order to operate so you are going to need to look at the power requirements in order to get something that will work properly for your needs. The last thing that you want to experience is a huge spike in your electric bill because you decided to put a new dehumidifier in the basement. Some units are better on electricity than others so it is worth your time to see what the power requirements are prior to purchasing a dehumidifier.

First, there are dehumidifiers that do not require electricity. These units instead use silica gel to absorb moisture from the air. They will continue to pull moisture from the air until the silica gel is fully saturated at which point you either need to replace the silica gel or dry it out to recharge it. Although recharging the silica gel requires some electricity, it only needs to be done once in a while so these units really don't need any measurable amount of electricity.

Large units require compressors and fans and therefore require electricity. The first thing you should look for is to make sure that the unit is Energy Star certified as this means it uses electricity efficiently. The other important consideration is to make sure that it has the proper capacity for the space you are using it in. If the unit is undersized, it will run in a continuous fashion and waste electricity. Finally, it's best that you purchase a unit that has a humidistat so that it only runs when the humidity is above a certain threshold. This will help to reduce its energy usage and save you money.

Features

Tank Capacity and Hose Hookup

Dehumidifiers work by condensing vaporized moisture into water which reduces the overall humidity in the air. As this process unfolds, you are going to need a place for the water to go. The most common design is to have a water tank where the water can be drained and have a design that will turn off the dehumidifier when the tank is full.

This means that the larger the tank, the longer the dehumidifier can run before you have to empty the tank. While a large tank may sound useful at first, you have to keep in mind that a larger tank is going to weigh more than it is full. That means you are going to have to work harder to pick up and carry the tank to a location where the water can be drained. In other words, you should select a tank size based on what you can comfortably carry so that you can empty your dehumidifier.

Additionally, your dehumidifier should have a hose hookup. This will let you bypass the tank and let the water drain into the hose. The hose can then be directed to a drain in the building. The advantage of using a hose is that you will never need to worry about having to empty the tank since it will always be empty. It is the perfect solution for when you plan on using a dehumidifier in a single location for a long period of time such as a garage or a basement. This will let you set up the dehumidifier and forget about it so that you can worry about other things in your life while keeping your building dry.

Advanced Features

Air Filter

There is a lot of debris that circulates throughout the air in your home. Some of this includes but is not limited to bacteria, dust, allergins, and dander. While a dehumidifier is not a total solution to removing such contaminants from the air, it will certainly help reduce them as air is pulled through it in order to remove moisture. Furthermore, as the filter starts to get dirty, the motor on the dehumidifier will need to work harder in order to operate. This means that you will want to look for a unit that has an air filter that can be replaced or even better, washed as needed.

An air filter that can be washed is best because it will reduce the maintenance cost of your dehumidifier. In most cases, the filter will be a screen that you just need to remove on a regular basis and then rinse it off in the sink. Once it is fully dry, you just need to put it back into the dehumidifier. There should be no need for any additional work.

It's possible that the filter is disposable or that there isn't even a filter. It's best that you avoid such designs whenever possible. No filter will mean that the dehumidifier doesn't remove any contaminants and this should only be acceptable on small room-sized units. Otherwise, you should expect your dehumidifier to contribute to the quality of the air in the building. A unit that has a disposable filter will contribute to air quality, but you need to go through the hassle of replacing the filter. That means you are going to have to find a retailer that sells the filters and make sure that the filters continue to be available.

Bottom Line

Quality

Poor quality tends to be the source of many poor reviews so you are going to want to think about the quality when you are purchasing a dehumidifier. Three of the most common complaints tend to revolve around the unit leaking water, noise, and lack of humidity control. When you are looking for a dehumidifier, you should be on the lookout for a unit that performs well in all three areas. Otherwise, you are less likely to be satisfied with your purchase.

Almost all dehumidifiers use fans and compressors to operate so noise tends to be an issue. Generally speaking, you are going to want to look for a unit that doesn't make a lot of noise. While it may be too much to expect that a unit runs silently, you most certainly do not want it to make a bunch of noise pollution either. If you find that a unit is loud or vibrates a lot, then you may want to look for a different model or brand.

Leaks are the other problem area that many people have issues with. They can happen when the tank leaks water itself. You can also get leaks if the unit doesn't turn off when the tank is full. Another source of leaks comes from when it is awkward to remove the tank causing you to spill. Finally, if the hose hookups do not seal properly you will have leaks.

The final issue has to do with the amount that the unit actually reduces humidity. Sometimes a unit will only reduce the humidity by a few percentage points. If this is the case, then you aren't getting what you are paying for. A good unit will create a noticeable difference in the relative humidity.

Set It and Forget It

There are two big things that you want to look for when you're getting a dehumidifier and that is capacity and drainage. All of the products on this list are going to do a good job of getting water out of the air, but the trick is what happens to that water. For our money a dehumidifier that has a hose attachment that is going to let the thing run as often as you need it is a really nice and important feature and it's worth the money. Simply put that allows you to let the humidifier do its thing without you having to change the bucket every time it gets full of water. And if you don't want that feature just make sure you've got a lot of water capacity.

Frequently Asked Questions

q: Why does my dehumidifier frost up?

a:

The water is condensed by creating a cool surface that is lower than the surrounding air temperature. Sometimes, the water freezes into ice when it comes in contact with the condenser because the condenser is cooler than what it needs to be. As more frost builds up on the condenser, it starts to insulate rather than dehumidifier which creates even more frost. You should always look for models that have a frost sensor that will turn the dehumidifier off until the frost melts.

q: Why isn't the humidity dropping when I run my dehumidifier?

a:

There are two common reasons for this. One issue is that you have purchased an undersized dehumidifier that isn't capable of removing all of the humidity. The other reason is that there is something wrong with the dehumidifier. For example, some dehumidifiers are poorly made and will not control the humidity well. You may have issues with them frosting up which causes it to fail or the humidity sensors on them may be bad as well.

q: What is the auto restart feature?

a:

Auto-restart is a common feature that is found on many brands of dehumidifiers. Units that do not have this feature will turn off and stay off in the event that you lose power in your home. That means that even when power has been restored, you have to manually turn your dehumidifier back on for it to run. This can be a problem if you are gone on vacation or away from the building. Auto restart turns the unit back on for you when power is restored.

q: When should I use a dehumidifier?

a:

You shouldn't have too much trouble knowing when and where you need a dehumidifier. Whenever you see fog on your windows, beads of water on your walls or floors, or puddles forming on the ground, you will want to use a dehumidifier. These issues are caused by moisture in the air condensing on these surfaces which is what causes the water to form on the walls, windows, or the ground. When you run a dehumidifier, the water should disappear.

q: How do I keep my dehumidifier from vibrating?

a:

You are going to need to identify the source of the vibration. For example, if the source of the vibration is coming from an unbalanced fan then there may not be much that you can do about it. If it's coming from loose caster wheels, then you can tighten up the wheels to reduce the vibration. Some people put their unit on a rubber pad which can absorb vibrations and help to reduce the noise caused by them.
