7 Best Dehumidifiers for Attic

An attic can serve many purposes in a home or building. It’s typically used as storage space but can also provide additional living or playroom when needed. Depending on the structure, this area could be insulated or uninsulated.

As the weather changes and humidity increases, it’s a good time to think about how to best protect your belongings tucked in the attic. One of the essential parts of this is ensuring that you have additional attic insulation and a dehumidifier. Here are some suggestions for which brands and models may be best for you.

Things to consider when buying a dehumidifier for the attic

1. Storage capacity

An attic can have many different uses, such as a guest room, playroom, storage room, home office, etc. How do you allocate the space for your belongings, and what dehumidifier size would be best?

While deciding on the storage space for your dehumidifier, it’s essential to figure out how much humidity is in the attic. To determine this, you can use a hygrometer. It’s a device that measures humidity levels in any conditions (e.g., high or low temperature).

2. Capacity of dehumidifier

A dehumidifier that’s too small for the area it’s covering can have a more difficult time removing high moisture levels. In turn, it may not be able to handle the problem and may cause more harm than good. Choose a model that’s right for your space. 

The most common model capacities include 25 pints, 50 pints and 75 pints. The higher the capacity, the more water the unit can extract in the same amount of time.

3. Humidistat controls

If you’re using an uninsulated attic as storage, your goal is to remove as much water as you can and prevent additional moisture from being present in the first place. To do this, you’ll need a dehumidifier with a humidistat. This will automatically regulate humidity levels to ensure optimal performance.

4. Dampness level in the attic

Again, it may be a naturally dry place, depending on how the attic is used. But even then, there will still be some humidity that can’t escape easily or accumulates over time. If you’re living in the attic, you’ll want to remove as much moisture as possible. Otherwise, it can damage your belongings as well as your health.

You’ll want to keep a closer eye on the humidity in the attic; otherwise, it could put you and others in harm’s way. For this reason, we recommend the best attic dehumidifier with a humidistat. This is an essential feature if you use your attic for living or play space purposes.

5. Tank size

With a dehumidifier, the larger the tank, the more moisture removed from the attic. A large capacity dehumidifier tank will get more work done sooner, and you won’t have to empty it as often.

6. Digital control operation

A digital control panel can allow you to efficiently operate your dehumidifier from anywhere in the room or from another room in your home. If you don’t want to move around to adjust settings for your appliance, this is an essential feature for you.
