Buyer Guide For the Best Dehumidifier for Attics 

There are different factors you need to consider when looking to purchase a dehumidifier for your attic. Some of these factors are:

  • Dehumidifier Capacity

The attic may be a small space in the home, but you want to make sure that the dehumidifying unit that you settle for will work great in your attic without issues. A large space dehumidifier may not be a cost-effective option if it will be meant solely for the attic.

The dehumidifier capacity for your attic should be at least one pint. Depending on how big your attic is, you may choose to go for larger sizes. However, a one-pint dehumidifying capacity will help to reduce the moisture levels in a 150 square feet space just fine. 

  • Water Bucket Size

The size of the water bucket in a dehumidifying unit will determine how often you empty the bucket to dispose of the water. While it may be convenient to opt for the units that offer extra drainage options via a hose connector, not all dehumidifiers meant for small spaces come with this option. 

The water bucket capacity for a dehumidifying unit meant for the attic should be at a minimum of one-pint. This will work conveniently for small attics, and larger sizes may be considered if your attic is a large one.

  • Convenient Use

The ease of use of any device affects the satisfaction derived from it. Any dehumidifying unit you are considering should be easy and convenient to use. The unit should be easy to set up on first use, and the controls should not pose a problem.

Besides the easy setup and control, cleaning, maintaining, and mobility influence the buying decision. Consider this when choosing the next best dehumidifier for attics.

  • Ease Of Water Removal

Small dehumidifiers may not offer multiple options for disposing of water from the water bucket. Nonetheless, emptying the water bucket by hand should be a straightforward option.

While disposing of water from the bucket manually may be the standard option, other dehumidifiers for attics have a hose connector along with a hose that can be used for continuous water disposal into an external tank or drain.

A dehumidifying unit will most likely be connected to a power source for most of the time for it to work. Not all units are energy star rated and deemed efficient at using power, but the power consumed by dehumidifiers won’t bore a hole in your energy bill. 

Dehumidifying devices will, on average, use a minimum of 220 volts to power on and start working.

  • Can I link my dehumidifier to and control it with my smartphone?

The smart function of connecting your dehumidifying device with your smartphone is a great option that makes the device easy to use and convenient.
