Choosing the Right Dehumidifier for Your Attic: A Smart Investment
Attics can get surprisingly damp. This moisture can lead to all sorts of problems, from mold growth to wood rot. A dehumidifier is a great way to keep your attic dry and healthy. But with so many options, how do you pick the best one? This guide will help you find the perfect attic dehumidifier.
Key Features to Look For
When you’re shopping for an attic dehumidifier, keep these important features in mind:
- Capacity (Pints per Day): This tells you how much moisture the dehumidifier can remove in 24 hours. Attics are often large and can hold a lot of moisture. Look for a dehumidifier with a high capacity, usually 40 pints or more, especially if your attic is large or very humid.
- Coverage Area (Square Footage): Dehumidifiers are rated for a certain square footage. Make sure the dehumidifier you choose can handle the size of your attic. It’s better to get one that’s a bit too powerful than one that’s not powerful enough.
- Drainage Options:
- Continuous Drainage: This is the most convenient option for attics. It lets the dehumidifier drain water automatically through a hose into a floor drain or sump pump. This means you won’t have to empty a water tank.
- Collection Tank: Some dehumidifiers have a built-in tank. If you choose this, make sure the tank is easy to remove and empty. You’ll need to check and empty it regularly.
- Humidistat: This is a sensor that measures the humidity level. It allows the dehumidifier to turn on and off automatically to maintain your desired humidity level. This saves energy and keeps your attic consistently dry.
- Automatic Shut-off: This safety feature turns the dehumidifier off if the water tank is full (if it has one) or if it’s about to freeze.
- Defrost Function: Attics can get cold. A defrost function helps prevent the dehumidifier from freezing up when temperatures drop.
- Air Filter: A good air filter helps remove dust and other particles from the air, improving air quality in your attic. It also keeps the dehumidifier’s internal parts clean.
- Noise Level (Decibels): While attics are usually out of the way, a quieter unit is always a plus. Check the decibel rating if noise is a concern.
Important Materials and Construction
The materials used in a dehumidifier can affect its durability and performance.
- Durable Casing: Look for a dehumidifier with a sturdy plastic or metal casing. This protects the internal components and ensures the unit lasts.
- Corrosion-Resistant Coils: The coils inside the dehumidifier are where moisture condenses. They should be made of materials that resist rust and corrosion, especially in a potentially damp environment like an attic. Copper or coated aluminum coils are good choices.
Factors That Improve or Reduce Quality
Several things can make a dehumidifier better or worse.
- Brand Reputation: Well-known brands often have better quality control and offer more reliable products. Researching brands can give you an idea of their track record.
- Energy Efficiency (Energy Star Rating): An Energy Star certified dehumidifier uses less electricity. This saves you money on your energy bills and is better for the environment.
- Build Quality: A well-built dehumidifier will feel solid and have smooth operation. Flimsy parts or rough edges can be signs of lower quality.
- Customer Reviews: Real users can tell you a lot. Read reviews to see how the dehumidifier performs in attics, how easy it is to use, and if people have encountered common problems.
User Experience and Use Cases
Using a dehumidifier in your attic is straightforward.
- Ease of Setup: Most dehumidifiers are plug-and-play. However, setting up continuous drainage might require a bit more effort.
- Maintenance: Regularly cleaning the air filter is crucial. If your unit has a collection tank, emptying it is the main task. A unit with continuous drainage requires very little daily attention.
- Placement: Place the dehumidifier in a central location in the attic to ensure it can effectively circulate air and capture moisture. Make sure it’s on a stable surface, away from direct water sources.
- Benefits: A dry attic prevents mold and mildew growth, which can damage your home and cause health problems. It also protects stored items from moisture damage. A dehumidifier can even help prevent ice dams on your roof in colder climates by reducing attic heat loss.
Frequently Asked Questions About Attic Dehumidifiers
Q1: Why do I need a dehumidifier in my attic?
A: Attics can trap moisture from the outside and from your home. This moisture can cause mold, rot your wood, and damage stored items. A dehumidifier removes this excess moisture.
Q2: How big of a dehumidifier do I need for my attic?
A: The size depends on your attic’s square footage and how damp it is. Look at the dehumidifier’s coverage area and its pint capacity. It’s usually best to get one rated for a larger area than you think you need.
Q3: What is “pints per day” capacity?
A: This is how much water the dehumidifier can take out of the air in a 24-hour period. Higher numbers mean it can handle more moisture.
Q4: Is continuous drainage important for an attic dehumidifier?
A: Yes, continuous drainage is highly recommended. It means the dehumidifier empties itself automatically, so you don’t have to worry about emptying a tank regularly.
Q5: How often do I need to empty the collection tank?
A: This depends on how humid your attic is and the size of the tank. You might need to empty it every day or every few days. A dehumidifier with a humidistat will only run when needed, which can help.
Q6: Will a dehumidifier freeze in my attic?
A: Yes, if your attic gets cold enough. Look for a dehumidifier with a defrost function to prevent this.
Q7: How much electricity does an attic dehumidifier use?
A: Dehumidifiers use electricity. Look for an Energy Star certified model, as these are more energy-efficient and will save you money on your power bill.
Q8: Can I store things in my attic if I use a dehumidifier?
A: Yes, a dehumidifier helps protect your stored items from moisture damage, mold, and mildew. Just make sure the items are not directly touching the dehumidifier.
Q9: How do I set up continuous drainage?
A: Most dehumidifiers come with a hose. You’ll need to connect the hose to the dehumidifier and run it to a drain, like a floor drain or a sump pump. Check the user manual for specific instructions.
Q10: How do I maintain my attic dehumidifier?
A: The most important maintenance is cleaning the air filter regularly. If you have a collection tank, empty it when it’s full. Keep the dehumidifier clean and free of dust.
