Too much moisture can turn your attic into a breeding ground for mold, mildew, and even damage to your home. That's why a dehumidifier is your attic's best friend!

In this guide, we'll break down everything you need to know about choosing the right attic dehumidifier and give you the inside scoop on the top models for 2024.

Let's find out!

Should I Put a Dehumidifier in My Attic?

can you use a dehumidifier in the loft

Imagine your attic like a giant sponge. It absorbs moisture from the air, especially in hot and humid weather. If you've noticed any of these signs, it's time to consider a dehumidifier:

A dehumidifier isn't just about keeping musty smells at bay. It's a wise investment in your home's health. An attic dehumidifier protects your stored belongings, prevents expensive structural damage, and even makes the air in your whole house feel fresher and cleaner.

What Size Dehumidifier Do I Need for The Attic?

Picking the right size dehumidifier is super important for getting the most effective moisture control. You'll need to consider a few key factors:

  • Attic Size: Measure the square footage of your attic to get a starting point.
  • Dampness Level: Is the problem a bit of occasional humidity, or is your attic a total swamp monster? This will determine how powerful your dehumidifier needs to be.
  • Temperature: Attics can get pretty chilly, especially in winter. Some dehumidifiers are specifically designed to keep working effectively even in colder temperatures.

As a general rule, a small attic with mild dampness might be fine with a dehumidifier rated at around 30 to 50 pints of water removal per day. Larger attics with serious moisture issues will need a heavy-duty machine that can handle 50 to 70 pints or more (for commercial attic space).

Guide to Installing a Dehumidifier in the Attic

Installing an attic dehumidifier doesn't have to be a nightmare. Here's a breakdown of the key steps:

  • Placement: Pick a spot with good airflow so the dehumidifier can work its magic. Aiming for the center of the attic is a good place to start. Make sure there's enough clearance around the dehumidifier for proper air intake and exhaust.
  • Drainage: You have options! You can empty the water bucket by hand for smaller units, run a drain hose to somewhere the water can go safely, or get a super-convenient attic dehumidifier with pump that does the draining for you.
  • Power: Make sure you have an outlet nearby to plug in your dehumidifier. Use a safe, heavy-duty extension cord if needed, and always prioritize electrical safety.

Things to Consider when Choosing the Best Dehumidifier for Attic

Choosing the right dehumidifier for the attic involves looking at a few important factors. Here's what to keep in mind:

  • Capacity: Measured in pints of water removed per day. Match this to your attic's size and moisture level.
  • Features: Think about things like built-in pumps, smart controls, automatic shut-off, and defrost functions (for cold attics).
  • Noise Level: Some dehumidifiers can be a bit loud. If noise is a concern, look for models with quiet operation.
  • Energy Efficiency: Dehumidifiers can use some electricity, so look for Energy Star-rated models to save on your power bill.
  • Durability: An attic dehumidifier needs to be tough to withstand attic conditions. Look for sturdy construction and good warranties.

Seasonal Considerations: Should You Use a Dehumidifier in the Attic Year-Round?

dehumidifier for attics in summer or winter

The short answer is yes!

While we often associate dehumidifiers with hot, humid summers, they're valuable tools for attic moisture control throughout the year.

Here's why:

  • Dehumidifier for Attic in Summer: Summer heat and humidity can turn your attic into a moisture trap. A dehumidifier combats this, preventing mold growth, protecting stored belongings, and even reducing the strain on your air conditioning system.
  • Dehumidifier for Attic in Winter: You might think winter dryness means no need for a dehumidifier. However, attics can still develop moisture problems due to condensation from temperature differences. A dehumidifier helps prevent these issues, keeping your attic healthier even in the colder months.

However, if your attic is well-insulated and ventilated, you might not need a dehumidifier year-round. A hygrometer (humidity measuring device) is a great way to monitor attic humidity levels.

Aim to keep it between 30-50% for optimal conditions. If your attic consistently falls outside that range, a dehumidifier is a wise investment regardless of the season.

Final Verdict

Think of an attic dehumidifier as a wise investment for your home and the belongings you keep in your attic. It keeps your attic dry and healthy, protecting your things, preventing musty odors, and safeguarding the very structure of your house.

Choose the dehumidifier that's the perfect match for your attic's needs, and you'll be breathing easier (literally!) for years to come.
