It’s also stackable, which makes transporting it a breeze. Be wary of the weight, though. At 78 pounds, this isn’t the most portable dehumidifier. It also doesn’t come with wheels, so you’ll need to be careful about moving it safely.

The Vremi comes with a removable tank and drain access, so you can decide how you want to use it. You’ll have to buy a separate hose if you want to run it continuously, though.
The tank can hold up to 22 pints, which some users found small compared to other basement dehumidifiers. The unit has an auto-shutoff feature, so it won’t overflow when the tank is full, but you may have to empty it once or twice a day if you run it a lot.

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 that 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 use the bathroom daily.

The Keystone has many smart features, including a transparent water level indicator and full tank alert. It also has an auto-restart function which will save your settings if there’s a power cut.
This unit allows continuous draining, although many users found this wasn’t as efficient as using the tank. Several customers also reported difficulty removing the bucket, which you’ll need to do to use the continuous draining function.

Do I Need a Dehumidifier?
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 bacteria, fungi, and allergens.
Having fungi and mold in the home can present serious health risks for you and your family. So it’s important to regularly clean, ventilate, and dehumidify your home.
Dehumidifiers collect excess moisture from the air. This 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?
The Environmental Protection Agency (EPA) recommends indoor humidity be kept below 60 percent. Most people find 40–50 percent is the sweet spot (1).
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 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.
- Easy to use.
- Great for warm or damp spaces.
- Usually uses less electricity than other dehumidifiers.
- Great for large spaces as they can dehumidify up to 70 pints per day.
- Difficult to move since they are larger.
- Coils can freeze in colder conditions.
- Can be noisy, with a minimal level of 40 decibels.
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 similarly, using materials such as silica gel to attract and absorb moisture.
- Portable, since they are more compact.
- Ideal for cold environments.
- Quieter than other types, often less than 35 decibels.
- Can be pricey to run.
- Not the best option for medium or large spaces.
- They are a more expensive option to buy.
