The 10 Best Dehumidifier Buying Guide and Reviews

Top 10 American dehumidifiers recommended. Is there heavy humidity at home? Solve with a dehumidification artifact!

The best dehumidifier can quickly and effectively remove excess moisture in the air. If you find a humid atmosphere in your home, it is best to use a dehumidifier as soon as possible. Excessive humidity can damage your house and cause mold, mildew, and water stains. It can also cause a musty smell that is difficult to mask.

The weather is relatively heavy, so it is necessary to have a dehumidifier at home. Generally, it is recommended to set the humidity below 60 degrees for a household dehumidifier, which can effectively prevent moisture and remove moisture.

By lowering the humidity in the home, the air will improve and become easier to breathe. Therefore, for those suffering from allergies, a dehumidifier is a good investment.

Most importantly, dehumidifiers have other benefits, such as drying clothes faster and reducing pests and termites. With all this in mind, there is nothing against buying a dehumidifier. Not sure which one to buy?

What is the appropriate humidity for the dehumidifier?

Setting the room humidity below 60% can effectively prevent moisture and dehumidification and prevent items from becoming mildewed. Wet quilts and mattresses seriously affect our sleep quality. We can use dehumidifiers to dry quilts and mattresses. The specific operation should be to close the door and set the humidity to the dry clothes stall when there is no one. Just set the humidity to the comfort level.

The dehumidifier cannot be placed next to the heater

Do not place the dehumidifier next to the heat source machine. The heat barrier and cold shrinkage can easily deform the machine. Moreover, the surface of the dehumidifier also needs to dissipate heat. If it is very hot next to it, the heat will not be dissipated. This will affect the dehumidification effect, increase the electricity bill, and may affect the life of the dehumidifier.

Benefits of dehumidifier

The dehumidifier can effectively control humidity, prevent items from getting damp, air-dry clothes, and prevent various diseases caused by humidity, such as rheumatism, arthritis, and other senile diseases.

It can lower the room temperature while dehumidifying in the hot summer. Therefore, it is very important to buy a cooling dehumidifier at home. It can prevent the production of bacteria during rainy or rainy seasons and protect the health of the whole family; while dehumidifying, it can effectively reduce the temperature and prevent heatstroke.

The necessity of dehumidification

The atmosphere is too humid, which is conducive to the growth and spread of some bacteria and germs. Scientists have determined that when the air humidity is higher than 65%, the growth of germs accelerates.

When the air humidity is higher than 65% and the humidity is too high, the amount of pineal hormone secreted by the pineal gland in the human body is also large, making the concentration of thyroxine and epinephrine in the body relatively low, and the cells will be "lazy."

People will feel dejected and depressed. Working and living in a place with high humidity for a long time is prone to rheumatism, rheumatoid arthritis, and other damp arthritis. To prevent the health risks of humidity, the first thing to do is to keep the room ventilated and dry. On rainy days, the outdoor humidity is relatively high.

You can close most of the doors and windows on the windward side, and only open the doors and windows on the downwind side to increase moisture into the room. Facilitate air circulation and accelerate the evaporation of water vapor; try not to dry clothes indoors on rainy days.

It is best not to bring wet clothes, umbrellas, and footwear into the room. Place a cushioned cloth at the door of the bedroom or at the door of the kitchen or living room to remove water stains from the soles. At the same time, you can consider adding a dehumidifier indoors to achieve a fast and effective dehumidification function.

Here, we list the best dehumidifiers you can find on the market and recommend them for your reference:

Frigidaire is a company with a long history. The company was founded in the United States in 1918 and is actually a subsidiary of Electrolux, a parent company headquartered in Sweden. This is well known in the cooling and humidity control industry. It has a series of dehumidifiers from large to small.

The company deserves its name too much for the first time. As early as September 1918, it claimed to be the first company to manufacture electric independent refrigerators. According to reports, it also has the first household food freezing product, the first room air conditioner, and the first 30-inch electric stove. Frigidaire also stated that they are the first company to produce color-coordinated home appliances. With all this history and innovation, you can rest assured that you are dealing with a company that knows how to produce quality products. This is why their dehumidifier series is so highly valued. This overall best dehumidifier Frigidaire FFAP5033W1 is no exception.

Frigidaire FFAP5033W1 It replaces the old Frigidaire FFAP7033T1. FFAP5033W1 has a convenient automatic pump to move water and a first-class design. It will quickly absorb water from the air and is easy to install, clean, and store. It has a larger water tank, and it no longer needs an adapter to use gravity drainage.

FFAD5033W1 is one of the best dehumidifiers we have tested. Comparing it side by side with any other 50-pint dehumidifier, it is clear that Frigidaire is made with higher quality parts and materials. The control panel buttons and LEDs are of higher quality. Its plastic is of higher quality. The plastic used in the collection bucket is thicker and of higher quality. Compared to the combined grille/air filter we see on most other equipment, the grille and the air filter are two separate, higher-quality components. Even the bracket used to wind the power cord around the back of the device is of higher quality. The quality of almost every component on this Frigidaire is significantly higher than the equivalent components on ordinary dehumidifiers.

The device has a timer that can be set up to 10 hours in half-hour increments, and from 11 hours to 24 hours in 1-hour increments. Most other timers on most other dehumidifiers have similar adjustability. The two exceptions are that units like GE ADEL45LY can only be set to 2 hours or 4 hours, while units like Toshiba TDDP5012ES2 can only be set in 1-hour increments, from 1 hour to 24 hours. It has 3 fan speeds. Most other 50 pint dehumidifiers, including hOmeLabs and Black+Decker, have only two fans speeds-normal and turbo.

It can be said that this Frigidaire FFAD5033W1 is a very high-quality dehumidifier. Comparing it side-by-side with other top equipment such as hOmeLabs HME020031N and Black+Decker BDT50WTB, it is clear that Frigidaire is higher quality equipment. It also performed very well in all our performance tests. Most importantly, it removes moisture faster than any other dehumidifier we have tested. Finally, you bought a dehumidifier to dehumidify.

Overview of HONEYWELL 70 PINT DEHUMIDIFIER dehumidifier:

The Honeywell 70 pint dehumidifier pump is an ingenious design and dehumidifier ability to solve the problem of humidity in medium or large rooms. Honeywell is a legendary company with a long history of manufacturing world-class products. This sturdy and reliable 70-pin dehumidifier is a good example of their work. Although we have not encountered an absolutely perfect machine, this machine is very close. You will find that there are many things to like, and there are almost no shortcomings in this unit.

Like most dehumidifiers, the Honeywell design team put most of its energy into a function rather than form. It is only designed to be functional, but its appearance is not ugly. It is unobtrusive and easily blends into the background, where it will steadily draw excess water from any space you decide to put in. It is not a quiet machine, but it does not produce annoying sounds. Once you get used to the sound it makes, it will fade into the background of ordinary household sounds, and you will hardly notice it.

Its specifications:

Overall product size: 12.4” x 15.8” x 25.4”
Product weight (no water in the tank): 49.2 pounds
Extraction capacity: 70 pints per day
Water tank size: 14 pints (1.75 gallons)
Power cord length: 5 feet
Including drain hose length: 16.4"
Power supply: 759 watts (maximum)

As you can see, this is not a very large unit, so it is not difficult to find a permanent place for it. However, don’t let its small size fool you, nearly 50 pounds; it’s much heavier than it looks, mainly because it hides a compressor and a dedicated pump in its humble housing.

In addition, this model also has automatic defrost and automatic restart functions. The former is used when frost starts to form on the coil, and the latter is used when the power fails. When the light comes back on, the device will restart and continue to run from where it left off. You can choose to operate the dehumidifier in one of two ways. You can set a specified amount of time (in hours) for the device to run before it automatically shuts down, or you can select a target humidity level in 5% increments and let the device run until the target you specify is reached.

Its built-in hygrostat is quite accurate, and you will find that it is very close to the relative humidity level displayed on the hygrometer. All the above functions are controlled through the panel located on the top of the device. The panel itself is well-designed and intuitive, so you won't have any problems mastering the machine operation. Of course, there are also pumps, in our opinion, this is the reason for buying this device. With the help of a dedicated pump, the use of the dehumidifier basically does not require manual operation. Apart from checking it every once in a while to make sure everything is running smoothly, there is really nothing to do. We like this technical function.

The device is equipped with a basic, washable filter. It doesn't have any fancy or over-advanced features, but it will help you capture pet dander, dust, pollen, and other indoor pollutants, and return to cleaner air than entering the unit, so this is also its significant advantage. The filter can be cleaned and reused, but remember that you need to suspend the operation of the machine every two weeks in order to rinse the filter well.

Finally, there is the quality issue. As we said at the beginning, Honeywell is a legendary company with a long history of manufacturing quality products and an equally long history of providing world-class customer support. Not surprisingly, this machine has an impressive five-year warranty and it is one of the best machines you can find anywhere. [ Purchase link ]

Buying guide for household dehumidifiers

How many pints of dehumidifier you need to buy depends on the size of the indoor space and the humidity level in the area. Humidity is a factor that will determine how you need to deal with excess moisture collected from the air. A smaller room may only require 30 pints, but a larger space may require 70 pints or more.

How many pints of dehumidifiers need to be purchased can be referred to from the following aspects:

Relative humidity: check the humidity level of the room
Square feet: Measure the size of a room.
Average temperature: Measure the average room temperature.
Dehumidifier size: Calculate the size of the dehumidifier you need.

Example: A room with an area of 500 square feet, relative humidity of 80%, and an average temperature of 70°F requires a 50 or 60-pint dehumidifier.

Step 1: Check the humidity level of the room

Rooms with high humidity, wet surfaces, or musty odors may require a dehumidifier. You can use a hygrometer to measure the humidity in a room, or you can evaluate it according to the following general standards:

If a space has a musty smell or sometimes feels wet in humid weather, it is considered humid.
If it is always damp and moldy, it is very humid.
If there is visible condensation on the ceiling or wall, it is a humid space.
With the presence of mold.
If there is condensation or standing water in a space, it also means that it is very humid.

Note: One way to check the humidity level in your home is to buy a hygrometer. Place it in the room you want to test and follow the instructions on how to use it. The hygrometer will display the percentage of humidity. Buy a hygrometer and place it in the room you want to test. Follow the instructions on how to use it. Record the percentage of humidity. If you find too much water in the room, you should take steps to eliminate or reduce it.

Step 2: Measure the average room temperature

To measure the temperature in the room, you need to use a thermometer. To calculate the temperature in the room, you can also download the app and use your phone’s sensor.

Step 3: Measure the size of the room

You need to measure the size of the room to determine how big a dehumidifier is needed for that room.

Measure the length of the room in feet.
Measure the width of the room in feet.

Multiply the two measurements to find the square footage of the room.

Example room 1: Square feet of space

If your room is 15 feet long and 20 feet wide, the room size is 300 square feet.

15 feet long
20 feet wide

Room space = 300 square feet.

Example room 2: Square feet of space

If your room is 25 feet long and 30 feet wide, the room size is 300 square feet.

25 feet long
30 feet wide

Room space = 750 square feet.

Step 4: Calculate what size dehumidifier I need?

Two dehumidifier size standards: used by the US Department of Energy

When you measure a house, there are two (US Department of Energy) standards for testing dehumidifiers.

The old standard in 2012.

New standards were adopted in 2019.

The dehumidifier can have different sizes. It used to be 70 pints, now it is 50 pints. The DOE size standard has changed. In 2012, the standard was based on the energy coefficient. The 2019 standard is based on a comprehensive energy factor, which is a more accurate way to measure how many dehumidifiers it can make. It also tests the dehumidifier at a lower temperature (65°F) than the old standard test temperature (80°F). This is why both the dehumidifier size table and the dehumidifier size calculator include the old and new capacities. After 2022, only the new standard will be used.

Can the dehumidifier cool down?

The dehumidifier is not only a device that can be used for dehumidification but also has a great performance in the problem of cooling. The cooling type dehumidifier is composed of a compressor, a heat exchanger, a fan, a water container, a casing, and a controller. The fan draws moist air into the machine and passes through the heat exchanger. At this time, the moisture in the air condenses into water The beads become dry air and are discharged out of the machine. The cooling type dehumidifier refers to the general dehumidifier, most of the condensation heat of the refrigerant is taken away by the water-cooled or air-cooled condenser, and only a small part of the condensation heat is used to heat the air after the evaporator, which can be used for cooling Dehumidifier for dehumidification. The air-cooled dehumidifier has a cool and dry wind, which has a certain cooling effect on the room. However, due to the limited cooling space, the temperature drops a little and does not change the space temperature too much.

Advantages of dehumidifier

It can effectively reduce indoor humidity, make the human body feel comfortable, and reduce the occurrence of rheumatism, arthritis, neuralgia, bronchitis, asthma, and other diseases. In order to effectively reduce the growth of mold and other bacteria, an environment with high humidity is a hotbed for the rapid reproduction of various bacteria. If the humidity is below 60%, bacteria and harmful microorganisms will be significantly reduced. It can effectively protect furniture, food, medicine, and books from moldy and deterioration. It can effectively protect household appliances, computers, cameras, instruments, and equipment from moisture damage. When the dehumidifier is activated in wet weather, the clothes can be dried effectively and quickly.

How to use a dehumidifier

First of all, place the dehumidifier in a place with air circulation, and avoid placing it in a dead corner that will cause poor ventilation and fail to achieve the dehumidification effect. In addition, please do not add irregular additives (such as perfume) to the water tank, which may cause the water tank and the base to be damaged. Cracks appear in the water part, which affects the normal operation of the machine. At the same time, the dehumidifier should also be checked during use. If the float is scaled and the weight increases, it will also lose the water-free automatic stop function, which will affect the dehumidifier's work.

Don't use in corners

The location of the dehumidifier is also very critical. It is best to place it in a place with air circulation. Generally, we place it in the middle of the room. There should be enough space around it, and no objects can be placed around the air outlet. Do not blow people directly from the air outlet, as the wind will cause people to catch a cold easily.

What size dehumidifier should I buy?

Below we will list a few examples to help you refer to:

Example 1: What size dehumidifier is needed for the basement? – 500 square feet

In some basements, there is too much moisture, high relative humidity, and high average temperature. This will cause high moisture content in the basement, where mold and spores grow. Over time, it will also make the walls of the house more fragile and put the entire house in danger, so buying a dehumidifier is a good choice:

Area: 500 square feet
Relative humidity: 80%.
Average temperature: 70°F.

If we look at the AHAM dehumidifier size table above, we can see that a basement with these specifications requires a 50 or 60-pint dehumidifier (according to the old standard) or 25-30 pints (according to the new standard). When you want to choose between two sizes of dehumidifiers, be sure to choose the larger size. It is better to have a more powerful dehumidifier than a dehumidifier that does not work well. The AHAM size chart does not take into account the average temperature. If you have a cold basement, you will need to add 10 pints per cubic foot.

Example 2: What size dehumidifier is needed for the whole house? – 1200 square feet

These are the sizes of small houses:

Area: 1200 square feet
Relative humidity: 65%.
Average temperature: 70°F.

We can infer that a house of this size needs a 70-pint dehumidifier (old standard) or a 50-pint dehumidifier (new standard). For larger spaces, you may need to consider large-capacity commercial dehumidifiers.

Large space over 2,500 square feet

If you often deal with excessive moisture and humidity and see things like mold or musty smell, then you need a whole-house dehumidifier. This is piped to your HVAC system. It can remove moisture before it enters your home. The whole house dehumidifier covers a large area (3000 square feet or more). The first price is higher, but in the long run, its cost will be lower. They can also help your air conditioner work better because it cools better when the air is dry.

Small spaces between 100 and 250 square feet

In a small room, it is difficult to install a large dehumidifier of 70 pints. This is why we recommend the mini version. Mini dehumidifiers can work quietly, they can cover 100-300 square feet. The mini dehumidifier is small and easy to use. They can be installed in bedrooms, children's rooms, or study rooms. Most small dehumidifiers also automatically shut down when the water tank is full. Most homeowners like the mini dehumidifier in the bedroom because it is small and quiet.

In general, we can choose a suitable dehumidifier according to the size of the room:

Small room dehumidifiers: These dehumidifiers are designed to control humidity in rooms under 500 square feet. They are most suitable for handling small and humid spaces such as bedrooms or offices.
Medium-sized room dehumidifiers: These dehumidifiers are ideal for dehumidifying medium to large damp spaces up to 1,000 square feet.
Large room dehumidifiers: Use these dehumidifiers to deal with a wider range of humidity problems, from excessive humidity to humid environments. This size is very suitable for large basements, crawl spaces, bedrooms, etc., with an area of 1,500 square feet.
Whole house dehumidifier: The whole house dehumidifier can be integrated with the existing HVAC system of the family. Many of these dehumidifiers can remove excess moisture in up to 3,000 square feet of space.

Or choose a dehumidifier according to the room type:

Crawling space dehumidifier: designed to solve the problem of humidity in a narrow crawling space.
Basement dehumidifier: If your basement has a musty smell or other dampness issues, please consider using a reliable basement dehumidifier.
Living area dehumidifiers: These single-room dehumidifiers are very suitable for use in bedrooms, living rooms, and other rooms.
Flood repair dehumidifier: useful during flood cleanup and recovery.
Industrial dehumidifier: suitable for manufacturing environment and warehouse. These commercial dehumidifiers can help employees keep facilities comfortable and protect your products from moisture damage.

FAQ about Best Dehumidifier Buying Guide and Reviews

Do I need a dehumidifier?

Dehumidifiers are the best way to remove excess moisture in your home and avoid problems caused by high humidity. These problems include mold and musty odors, warm, humid, and uncomfortable environments, condensation on windows, uneven floors, or structural damage. If these problems are ignored, allergic reactions, breathing problems, and other health problems may occur. So we can avoid the above problems by buying and using dehumidifiers to maintain a healthy humidity level.

How does the dehumidifier work?

The design of the dehumidifier is very simple. Its working principle is: suck moist air into the device and cool it with a condenser to remove the moisture in the air. The moisture drawn from the air is collected in the barrel inside the dehumidifier, and the fan is used to redistribute the dry and dehumidified air back to your environment. Dehumidifiers are usually placed in areas with humidity problems, such as basements, bathrooms, crawl spaces, bedrooms, and commercial areas with high humidity.

What is the ideal humidity level for my basement or living space?

The ideal humidity level for a home is 45-50%. Relative humidity levels higher than 50% can create an environment where mold spores, dust mites, bacteria, and even harmful pests can thrive. Relative humidity levels below 30% can be equally destructive. It can cause cold and flu viruses to increase, skin and respiratory tract irritation, cracked ceilings, separation of wooden floors, etc. Look for a dehumidifier with a humidistat, such as a Danby dehumidifier, which will automatically maintain the room temperature you set.

Where should I put the dehumidifier?

The best location for the dehumidifier is the room where you need it most. Dehumidifiers are usually placed in bedrooms, basements, laundry rooms, crawl spaces, and indoor swimming pool areas because these areas often have moisture problems. Most manufacturers recommend placing the dehumidifier at least six inches away from a wall or any other structure that might obstruct airflow in and out of the dehumidifier.
