Dehumidifiers Buying Guide 2022 – Everything You Need to Know
A dehumidifier is an appliance that removes moisture from the air. This can be helpful for people who live in humid climates or have issues with excess moisture in their homes. Dehumidifiers come in various sizes and models, so it can be tricky to know which one is right for you.
In this buyer’s guide, we will outline the different types of dehumidifiers available and offer tips on choosing the perfect one for your needs.
What are dehumidifiers?
A dehumidifier is an appliance that draws moisture from the air. It works by cooling the air it pulls in, which causes water to condense on its coils. This water is then collected in a basin or bucket for disposal. Dehumidifiers can help people who live in humid climates or those with issues with high levels of moisture.
Humid air naturally contains more water vapor than dry air, so dehumidifiers are especially useful in areas like basements and crawlspaces where humidity levels are naturally higher. They can also be beneficial in bathrooms, laundry rooms, kitchens, garages, or other spaces with high moisture levels due to showers or cooking.
Although dehumidifiers come in various styles and sizes, most operate by the same general principles. To remove moisture from the air, the first draw it in through their cooling coils, where water droplets form as the warm air cools and condenses. The water is either drained directly into a basin or bucket or deposited into a removable tank for later disposal.
Types of Dehumidifiers
Dehumidifiers are available in many different styles, shapes, and sizes. The size of your home or another area in which you plan to use the dehumidifier will largely determine which type is best for you.
Below are just a few of the most common types of dehumidifiers on the market today:
1. Desiccant dehumidifiers
Desiccant dehumidifiers draw water vapor from the air by combining it with a drying agent such as silica gel or similar desiccants. They are known for their energy efficiency and quiet operation.
Frost-free dehumidifiers use coils that run directly over the compressor, so they do not need to defrost manually like other models. Moreover, they tend to come with a larger capacity to collect more water before overflowing.
Desiccant dehumidifiers are best for people looking for a quiet unit, as they use a fan to suck air over the cooling coils. They can be used both indoors and out, and some models come with wheels for added portability.
This type of dehumidifier is small and lightweight, making it easy to carry from room to room. They are equipped with a handle and small wheels, and some even come in bright colors for added style.
Water collection tanks vary depending on the model you choose, but they tend to be smaller than other units – requiring more frequent emptying as a result.
Most desiccant dehumidifiers can run continuously due to their energy-efficient design. This makes them best for use in smaller rooms such as bathrooms and bedrooms, where they will be able to collect enough water over a relatively short period of time.
2. Refrigerant dehumidifiers
Refrigerant dehumidifiers are the most common type of unit. They use a compressor to cool warm air, causing it to condense into the water which is then collected in a tank or basin for disposal. Depending on the model, this can be done through gravity drainage or by using a pump.
Refrigerant dehumidifiers are equipped with large tanks and powerful motors, making them ideal for use in larger spaces such as basements and living rooms. They also tend to be noisier than other types of dehumidifiers.
With water collection tanks that can hold up to one gallon of water at a time, refrigerant dehumidifiers are best for people who need to remove large amounts of water from the air.
This type of dehumidifier is ideal for use in areas that have both hot and cold temperatures, as it can be ventilated through an exterior hose. This makes them great for basements, garages, and other areas where humidity levels tend to be higher.
3. Electronic dehumidifiers
These units work by emitting electromagnetic waves, which interact with the water molecules in the air and create a force that pulls them down into a collection basin. They are known for their energy efficiency, but they may not be as durable or well insulated as other types of dehumidifiers.
Because they do not use a compressor or fan, electronic dehumidifiers are significantly quieter than refrigerant and desiccant models. This makes them ideal for bedrooms and study spaces where noise levels need to be kept to a minimum.
Electronic dehumidifiers come with an internal pump that can help expel water collected in the basin. This allows them to be emptied without assistance and means you can put them above or below your floor level.
This type of dehumidifier might not be as durable as other models; however, it tends to last for a long time because it does not contain any moving parts such as fans or compressors.
Electronic dehumidifiers are best used in smaller spaces, such as bedrooms and offices. They come with built-in handles that make them easy to move from room to room, and some models include wheels for added convenience.
Electronic dehumidifiers tend to be small and lightweight compared to other types of units. This makes it easy to move them from room to room, and some models even come in bright colors for added style.
Benefits of Using Dehumidifiers
1. Helps remove excess moisture from the air
A dehumidifier pulls air over a refrigerated coil, causing the water in the room to condense into droplets that are then collected.
This process helps draw out humidity and restore your home’s ideal humidity levels; however, it can cause problems if you do not properly maintain your unit.
If the air coming out of your unit is humid, it means that there is still moisture left in the air after the appliance was able to extract it. This can lead to mold growth and damage to your property.
By running a dehumidifier even when you do not feel any humidity in the air, you are keeping the room at an ideal temperature for mold spores; this prevents them from growing and reduces their overall impact on your home.
2. Prevents health problems caused by excess humidity
Excess humidity causes many different types of respiratory problems because it encourages mold spores and dust mites to grow – leading to things like coughing, sneezing, skin irritation, eye irritation, asthma attacks, and more.
Humid air can also cause damage to your home by encouraging mold growth and destroying the structural integrity of your wood furniture; humidity weakens wood fibers, making it easier for them to split and break.
Dehumidifiers help keep your home’s interior at a comfortable temperature for both you and other people living there. This is because cool air holds less moisture than warm air – meaning that running a dehumidifier throughout the day helps maintain ideal levels of humidity even when the weather is hot outside.
When the air in your home is not humid, it makes it easier for you to breathe, relieves skin irritation, reduces dust mite populations, and prevents damage caused by excess moisture.
3. Prevents mold and mildew
Keeping your home at a comfortable humidity level is one of the best things you can do to prevent the growth of mold and mildew.
Mold spores thrive in warm, moist environments; running a dehumidifier during humid months helps reduce the number of spores entering your home, making it harder for them to take root.
Be sure to clean your unit’s air filter regularly – this will help remove any mold that has collected on its surface, reducing the risk that bits of it will end up in your lungs when you are breathing near it.
By running a dehumidifier throughout the summer, you also prevent water from pooling on surfaces inside your home. This reduces damage caused by leaks, water spills, and even overflowing toilets.
Mold growth on floors and walls can cause structural problems that lead to costly repairs; preventing this from happening is a very good reason to invest in a dehumidifier for your home.
4. Helps prevent furniture damage caused by excess moisture
Inside a humid house, the wooden components of your furniture are constantly exposed to moisture. This ensures that they stay at an ideal level of humidity-
This continuous exposure weakens your wood furniture; it can make it harder for you to put together or take apart certain pieces such as chairs and bed frames, making them more likely to break when they have moved around too much. Continued exposure also makes it easier for mold and mildew to grow.
The excess humidity in your home makes it difficult for wood furniture to maintain its structural integrity; with a dehumidifier, you can keep the atmosphere of your home at a comfortable moisture level and reduce damage caused by excess levels of humidity.
5. Reduces condensation on windows and other surfaces
When the air inside your home is humid, water droplets form on cold surfaces like walls and window panes because they are exposed to cool air.
This is called condensation, and it is usually not dangerous; however, when combined with excess humidity in the air surrounding these surfaces, this process creates ideal conditions for mold growth that can cause damage to your home’s structure or decoration.
Not only will dehumidifiers reduce the number of water droplets forming on the surfaces in your home, but they also prevent excessive humidity in the air from leading to condensation.
6. Saves money by reducing energy bills and extending product life
When you invest in a dehumidifier for your home, you can expect it to save you a lot of money over time because of all the benefits it provides.
For example, humid air causes your AC unit to work harder.
Running a more powerful AC unit means that your electricity bill will be higher than usual – ensuring that there is cool enough, dry air inside your house will help keep your cooling costs down even during hot summer months when more people are likely to need their units turned up.
As we mentioned earlier, dehumidifiers for homes and offices can prevent problems like mold growth that lead to expensive repairs; some of the most influential models also come with features that protect them from damage caused by excess humidity in the air.
These advanced features include sealed systems that keep unpleasant odors from entering your home, as well as technologies designed to shut off the machine if it detects an issue such as a blocked air intake or low water levels.
Many of today’s DC-based dehumidifiers only require about 4 amps on their electrical circuits – running even one unit 24 hours a day results in significant savings compared to using fans and other simple solutions.
For example, an average household might spend $2 per month on electricity to operate a single 1-inch window fan for 12 hours a day.
A dehumidifier running at the same rate would cost only about $ per month, and you wouldn’t have to worry
about using it as often during humid months just to keep comfortable inside your home.
7. Simple installation process
Dehumidifiers provide many benefits that improve your living conditions and lead to significant savings on your utility bills, but they are also very user-friendly. In most cases, you will turn them on – with a long press of a button or the flip of a switch – and watch as they begin their work immediately.
The machines usually include indicator lights or automatic shutoff systems that indicate when they are full of water or have a problem, so you can have peace of mind knowing that your unit is running properly.
In most cases, these units also come with a drainage hose and a collection bucket, making it very easy to empty the machine when it becomes full.
