The creme de la creme of dehumidifiers.

Buying a dehumidifier can seem overwhelming if you don’t know what to look for. With so many different brands and models vying for your attention, it’s no wonder many people get decision fatigue when shopping for a new one.

How big should it be? Do you need one for every room? What on earth is reservoir capacity?

Learn everything you need to know in this ultimate guide to the best dehumidifiers.


Do I Need a Dehumidifier?

You may be surprised how much moisture is actually in your home. Everyday activities such as showering, cooking, or hanging washing up inside all leave moisture in the air.

If your home is old, uninsulated, or doesn’t get a lot of sunlight, this moisture can linger and become trapped in your walls, floor, and ceiling. Damp homes are breeding grounds for all sorts of bacteria, fungi, and allergens.

Having fungi like mold in the home can present some serious health risks for you and your family. So it’s important to clean, ventilate, and dehumidify your home regularly.

Dehumidifiers work by collecting excess moisture from the air. This, in turn, lowers humidity levels and makes it harder for mold and dust mites to thrive.

Signs you should consider investing in a dehumidifier include:

  • Condensation on the walls or windows.
  • A musty odor.
  • Visible mold or mildew.
  • Allergic reactions to mold or dust mites.
  • A stuffy feeling inside.
  • Peeling wallpaper or blistering paint.

What Is the Optimal Humidity Setting?

Some humidity in the air is good, as too-dry environments come with their own health risks (1). However, if you or someone in your household suffers from allergies or a respiratory condition, it’s crucial you balance the humidity in your home.

The Environmental Protection Agency (EPA) recommends indoor humidity be kept below 60 percent. Most people find 40–50 percent is the sweet spot (2).

Maintaining a healthy humidity level will help prevent dust mite infestations and mold and mildew growth. This can greatly improve the health of you and your family.

How to Choose the Right Size Dehumidifier

The size of your dehumidifier will depend on the size and dampness of your home. Just want to dehumidify a small room like a bedroom or office? Then you can get away with using a smaller dehumidifier.

What if, however, you want to use your dehumidifier in a large garage? Or, perhaps, in an open-plan living area? Then you’ll need something that can hold more water.

You should also consider whether you’ll be moving your dehumidifier between rooms or even buildings. This will determine whether you go for a heavier device or a lighter, portable one.

Types of Dehumidifiers

There are several types of dehumidifiers and which one you choose will depend on your home, budget, and individual needs. The two most common dehumidifiers are compressor dehumidifiers and desiccant dehumidifiers.

Compressor Dehumidifiers

Compressor dehumidifiers use a fan, heat pump, and heat exchange coils to collect moisture from the air. The coils are extremely cold which causes moisture to condense and collect in the tank. These are the most popular types of dehumidifiers and are best for warm, damp rooms.

PROS:
  • Easy to use.
  • Great for warm or damp spaces.
  • Usually uses less electricity than other dehumidifiers.
CONS:
  • Difficult to move.
  • Coils can freeze in colder conditions.
  • Can be noisy.

Desiccant Dehumidifiers

You know those little silica gel packets you get when you buy new shoes, bags, or electronics? They’re there to attract moisture and protect your new purchases. Desiccant dehumidifiers work in a similar way; using materials such as silica gel to attract and absorb moisture.

PROS:
  • Portable.
  • Ideal for cold environments.
  • Quiet.
CONS:
  • Can be pricey to run.

How to Choose the Best Dehumidifier

Doing your research to find the right dehumidifier for your needs will ensure you are satisfied with your purchase and save you money in the long run. Here are some of the things you should consider before making a purchase.

Indoor Temperature

As with size and weight, this will depend where you’ll be using your dehumidifier most. Planning on setting it up in a cold area of the house — such as the garage or basement? Then you need to check that the unit can withstand lower temperatures.

Remember, the coils are extremely cold, so lower temperatures may cause them to freeze!

Noise

Dehumidifiers can be loud! Usually, the bigger the unit is, the noisier it will be. This is something to keep in mind if you prefer a quiet home or want to dehumidify your child’s room while they sleep.

In this case, a smaller, portable dehumidifier might be your best bet. They don’t have room for all the moving compressor parts that create noise. As such, they’re generally quieter and more peaceful.

Tank Capacity

Your dehumidifier’s tank — or reservoir — capacity will determine how much water it can hold. This will, in turn, determine how often you’ll need to empty it.

Want to set your dehumidifier going and not worry about it for a while? It might be best, then, to get a larger unit that will take longer to fill.

However, if you don’t mind emptying the tank every day and want the convenience of a portable dehumidifier, a smaller unit may be just what you’re looking for.

Built-in Pumps

If you don’t want to worry about emptying tanks at all, you can opt for a unit with a built-in pump. These don’t come with a tank to collect water and are designed to extract moisture from the air in a continuous flow.

Since they don’t have space to collect water, you’ll need to position the pump near a drain or vent. This would allow the vapor to escape.

Additional Features

Modern dehumidifiers are packed with features to make your life easier. Here are some common features you might want to look for:

  • Humidistat or hydrostat: These instruments measure the humidity in the area and allow you to set your optimal humidity level.
  • Auto-shutoff: This is handy if your unit has a tank to collect water because it will automatically switch off if the tank becomes too full.
  • Full tank alert: Similar to the auto-shutoff feature, this prevents your tank from overflowing. It notifies you when the tank is full and needs to be emptied.
  • Clean filter alert: As the dehumidifier sucks in air, its filters collect dust and debris floating about. The clean filter alert will notify you when you need to clean the filters to keep the unit running smoothly.
  • Defrost: This feature is invaluable if you use your dehumidifier in cold areas where the coils can freeze. The defrost function allows you to quickly and safely defrost the coils. Thus, you avoid damage to your machine and ensure it continues to run smoothly

In most houses, the bathroom is the dampest room. Even if you’re blessed with a dry home, regular showering, damp towels, and limited space means there is a lot of moisture in bathrooms. This is why it’s worth getting a small dehumidifier to keep in your bathroom, even if you have a dehumidifier for the rest of the house.

The Seavon is an excellent choice. It’s compact, so you can store it out of the way on a window sill or shelf.

This product also performs incredibly well, collecting up to 16 ounces a day. While this won’t be suitable for your whole house, it will keep your bath mat, ceiling, and mirror dry even when multiple people are using the bathroom every day.

Dehumidifier FAQs

There are a couple of things you might want to know about placement and operation before you buy a dehumidifier.

Where Is the Best Place to Put a Dehumidifier?

This will largely depend on your home and lifestyle. Many people find they only need a dehumidifier for certain problem areas in their house such as the bathroom or basement. Others find they need one in multiple rooms to get a manageable humidity level for the whole house.

Finding the best place for your dehumidifier may take some trial and error. If you’re not sure where to place your dehumidifier, we recommend opting for a portable unit. That way, you can move around as needed.

What Fan Speed Should I Use?

Most dehumidifiers come with three fan speeds: low, medium, and high. Higher speeds will collect moisture faster, meaning you won’t have to run your dehumidifier for long.

Bear in mind, however, that higher speeds generally create more noise. So, if you’re running the unit at night or in a quiet office, you may want to opt for a lower setting.

How Long Should I Run the Dehumidifier?

This depends on the size of your unit and the humidity level in your home. You don’t need to run it 24/7; in fact, this will make your electricity bills skyrocket!

We recommend measuring the humidity levels in your home and running your dehumidifier in any areas that are over 60 percent. You can switch the dehumidifier off when the humidity level drops below 50 percent.

Does the Dehumidifier Filter Need to be Replaced?

Most dehumidifiers have removable filters you can clean and reuse. Some models, however, use disposable filters that you will need to replace regularly. Check your manual or contact the manufacturer to find out how to replace or clean the filter on your particular model.

Do I Need to Buy a Separate Hygrometer to Measure Humidity?

Many modern dehumidifiers have built-in hygrometers — or humidistats — to measure the humidity in your home.

If your model doesn’t have one, we recommend buying a separate one. This will allow you monitor the moisture levels in your home and ensure your dehumidifier is working efficiently.

How Much Electricity Does a Dehumidifier Use?

How much electricity your dehumidifier uses will depend on the model, its size, and how frequently you use it.

If you want to keep your electricity usage down, we recommend looking for an energy-efficient model. Look for the Energy Star rating. This means the unit uses up to 20 percent less energy and they usually cost the same as other models.

How Much Does It Cost To Run a Dehumidifier?

How much you spend to run your dehumidifier will depend on the size of the unit and how many hours a day you run it.

You can run smaller dehumidifiers for as little as $25 a year. Larger units (70 pints or more), on the other hand, can cost up to $350 a year. Most dehumidifiers will cost around $100 a year, depending on the model and how often you use it.


Breathe Easy

Choosing the best dehumidifier for your home and lifestyle will help you breathe easier at night—literally! Dehumidifiers have a range of health benefits from preventing sickness to alleviating the symptoms of pre-existing conditions such as asthma.

Whether this is your first dehumidifier or your tenth, it’s important to consider how you’ll be using it before you hand over your hard-earned cash. Use our guide as a starting point for your own research. Be sure to look into the size, efficiency, and features of your ideal dehumidifier.
