How To Choose A Dehumidifier For An Attic

There are a few factors you need to consider when shopping for a dehumidifier for your attic. They include the following, among others:

Power Consumption

You want to get a dehumidifier that will not suck up too much power. Some models are more power-efficient than others. Be sure to look at the power consumption of the model you’re considering.

Size of The Dehumidifier

Get a unit that is appropriate for your space. A small, single-room attic might not need a 50-pint model. At the same time, an entire house could benefit from one, especially in basements and other less accessible areas where humidity levels tend to be higher.

Noise Level of The Dehumidifier

You want to make sure that you can sleep through the night if your unit is in a bedroom. Some models are quieter than others, so be mindful about what features and noise levels might work best for you.

Durability

A good dehumidifier should be able to withstand the elements while still running efficiently. Be sure to get one that is designed for durability and ease of use.

Warranty

All units come with some sort of warranty, but it’s important to note the length of coverage for each model you’re considering so you know what kind of peace of mind accompanies your investment in this product.

Simplicity

This is another factor to consider when shopping for a dehumidifier. Get one that is easy to use and does not require too much maintenance or upkeep on your part so you can enjoy all of the benefits without any hassle.

Capacity

The capacity of the dehumidifier is another factor to consider. If you have a large space, you will need to get a more powerful dehumidifier. If your attic is small and has fewer humidity problems, then the smaller units would be sufficient for your needs.

Ease Of cleaning

How easily a dehumidifier can be cleaned is also an important factor to consider. Most units have a removable container that you can take outside and empty, while others require special cleaning solutions.

Cost

The price of the dehumidifier is also something to consider before making your purchase. You don’t want to get the cheapest unit on the market.

Still, you don’t want to spend an arm and a leg either. You’ll want to get the best bang for your buck without overspending unnecessarily.

The cost of a dehumidifier varies from model to model, but you can find some that are very reasonably priced while still getting great quality.


FAQ

What should the humidity be in an Attic?

In the heating season, the humidity in your attic should be between 40% and 50%. This will help prevent damage to your houses like plaster cracks, mold growth, and wood rot.

In the cooling season, you want humidity levels in your attic at about 60%, so it helps keep cool air from escaping into the outside environment.

It is, however, recommended that you use a dehumidifier to help maintain the appropriate humidity levels in your attic.

Will a Dehumidifier Cool An Attic?

Yes. A dehumidifier can cool down attic spaces by as much as 20 degrees Fahrenheit. This happens because it gets rid of moisture, which is a heat-trapping agent.

Another way the cooling effect comes is from the dehumidifier’s fan. The fan cools down by blowing air over a cold coil, which then blows out cooler air.

How To Drain Dehumidifier In An Attic

To drain a dehumidifier in the attic, you will need to get a bucket and plug the sink. You can then attach the hose or pipe from your dehumidifier to the faucet to drain it into your container of choice.

You can also disconnect the hose from your dehumidifier and place it in a container of choice. Better still, you can attach the hose to an outdoor spigot and drain it there.

Sign of Moisture In The Attic

The signs of moisture in the attic include mold, mildew, and rotting wood. There can also be signs of leaks or soggy insulation. If you notice any of these signs, you should have your attic checked for moisture.

What Size Is Good For The Attic?

The size you buy will depend on how much humidity there is, but most units have capacities ranging between 40-50 pints per day or even more for larger spaces.

How Often To Clean A Dehumidifier?

To keep your unit running efficiently, make sure to deep clean it once every two weeks by emptying the water tank and wiping down all surfaces inside the machine with soap and warm water.

Conclusion

Hopefully, this article has provided you with some information about the best dehumidifiers for your attic. We compiled our list of the top five based on features, price, and overall quality.

The next time you are going shopping for a dehumidifier for your attic, use our tips to narrow down your search.

However, we recommend getting the Frigidaire Dehumidifier.

While this product is not the cheapest, it is still affordable while providing great quality. It is also very easy to clean and has a capacity of 35 pints per day.
