If you have high humidity in your attic, there’s a good chance you will suffer from problems with mold. One way to reduce the humidity in your attic is with a dehumidifier. We recommend the hOmeLabs (link to Amazon) range of dehumidifiers and I will explain why in this article.

However, whilst a dehumidifier will certainly help, it won’t fix the root cause of the problem. In this guide, we will also go over some of the common root causes of high humidity in the attic, and other questions you’re likely to have.

Quick Look at our Recommendation

The dehumidifier we recommend for attics are the hOmeLabs dehumidifiers. The main reasons we chose this specific model is that it includes continuous draining which means you won’t have to keep going up to the attic to empty the tank (as long as you have somewhere to drain the water), and it also has a 2 year warranty which is longer than most.

There are three sizes available so you should have no problem choosing one which will be a good fit for the size of your attic.

Is My Attic Too Humid?

If you’re not quite sure whether or not your attic has a problem with too much humidity, the best way to check is with a hygrometer. These are little devices a bit like thermometers but they measure humidity levels rather than temperature. Check out the ThermoPro TP50 on Amazon. Ideally, the humiditiy level should be between 35% and 50%. If it’s much higher than 50% then you’re going to start to see problems associated with high humidity.

You can also tell if the humidity levels in your attic are too high by the presence of mold. If you see small black and greenish dots on material, this is probably mold caused by too much humidity in your attic. Condensation on windows and glass surfaces is another sign of high humidity.

Is a Dehumidifier the Best Solution?

If you are having problems with high humidity levels in your attic, then of course, a dehumidifier is going to bring the humidity down which is a good thing. However, a dehumidifier will not address the root cause of the problem and you should also look at why the humidity levels are too high in the first place. We’ll look at some of the common causes next.

Dealing with the Root Cause

If you have too high humidity in your attic, a dehumidifier is certainly a good idea. However, you should also try to find out the root cause of the humidity. Below are some of the most common causes of high humidity in an attic.

  • Poor ventilation: You need to make sure there is adequate ventilation in your attic to allow warm, moist air to escape.
  • Other appliances venting air into the attic: If any appliances such as clothes dryers or bathroom exhaust fans are vented to the attic rather than outside, this will increase the humidity in the attic.
  • No barrier between the attic and the rest of the house: If there is no vapor barrier between the attic and the rest of your house, warm and moist air from your house will rise into the attic.
  • Leaking roof: Another potential cause of high humidity in the attic is a leaky roof which allow moisture from outside into the attic.

What to Look for in a Dehumidifier for an Attic

There are lots of dehumidifiers on the market. Below are the key things we suggest looking out for when choosing the best dehumidifier for an attic.

  • Continuous draining: Some dehumidifiers can only be used with the internal water tank. If there’s somewhere you can drain the water in your attic, we recommend choosing one with continuous draining which means you won’t need to keep going up there to empty the tank (this can be as often as a few times per day). If you want to drain the water out of something higher than the dehumidifier, you will also need a pump. Some dehumidifiers include a pump. The dehumidifier doesn’t include a pump so if you need one you will need to purchase an external pump like the Little Giant (link to Amazon).
  • Size: Dehumidifiers come in different sizes. The most common are 30 pint, 50 pint, and 70 pint. This refers to how much water they can extract withing 24 hours. Most dehumidifiers also suggest a recommended room size to help you choose the right size. It’s always best to go on the big side with a dehumidifier if you want the most effective results.
  • Warranty: Like all appliances, dehumidifiers can go wrong. We recommend purchasing a dehumidifier with a good warranty to keep your mind at ease. The hOmeLabs (link to Amazon) dehumidifiers which we recommend for attics have a 2 year warranty which is better than most alternatives.

Where to Place a Dehumidifier in an Attic

The placement of a dehumidifier in your attic is the same as for any other room. Ideally, it wants to be located as centrally as possible so the whole room can be dehumidified evenly. If you can’t position it centrally, it should be at least 6 inches away from walls or any objects that can interfere with airflow.

Best Dehumidifier for an Attic

If you want to use a dehumidifier in your attic, we recommend the hOmeLabs (link to Amazon) range of dehumidifiers. There are three sizes available, so you should be able to find one suitable for the size of your attic. It also has the option for continuous draining, and whilst it doesn’t include a pump, you can pick up a pump like the Little Giant on Amazon for a reasonable price if you really need one.

The main reason we chose this particular model over similar alternatives is the 2 year warranty. Appliances like dehumidifiers are known for running into problems so this extra protection should put your mind at ease.

Below, I will run you through some key points for the hOmeLabs dehumidifiers.

  • Warranty: Dehumidifiers are known to have problems with faulty units, so the 2-year warranty included with these hOmeLabs dehumidifiers will put your mind at ease.
  • Sleek design: Often, dehumidifiers can be an eyesore, but the hOmeLabs dehumidifiers actually look quite good.
  • Designed for low temperatures: The hOmeLabs dehumidifiers are designed to be used in temperatures between 41°F to 95°F which makes them ideal for low temperature rooms.
  • Continuous drainage: These dehumidifiers can be used with a drain hose so you won’t have to constantly empty the water tank. The hose itself is not included though and you will need to purchase it separately. This dehumidifier doesn’t include a pump either, so if you want to drain it out of something higher than the dehumidifier, you will need an external pump like the Little Giant (link to Amazon).
  • Auto shutoff: There is an auto shutoff which activates when the tank is full or the set humidity level is reached. Most people find the auto shutoff feature to work perfectly, but some have had issues with it not shutting off even when the set humidity level is reached.
  • Mobile: All three models have built-in wheels and carry handles which makes them easier to move around.
  • Relatively quiet: For the most part, users have been pleasantly surprised with how quiet these dehumidifiers are, although a few reviews suggest they are a little on the noisy side. However, you have to consider that all dehumidifiers are going to make some noise.

Overall, the hOmeLabs dehumidifiers offer everything you could want. There are models available for multiple rooms sizes, they are suitable for attics, they include a good warranty, and the features make them super easy to use.

Conclusion

To wrap it up, if you have problems with high humidity in your attic, purchasing a dehumidifier is a good idea, but you should also try to figure out the root cause of the problem. You can use a hygrometer to test humidity levels or if you notice mold on material in the attic, this is a good sign that humidity levels are too high. We recommend the hOmeLabs (link to Amazon) dehumidifiers for an attic due to the continuous draining and excellent warranty.
