Best Dehumidifiers for a Clean Garage

Dehumidifier products - Best Dehumidifier for the Garage

Unlike most areas of your home, you may not have built-in temperature and humidity control in your garage, making it more susceptible to temperature and humidity fluctuations, depending upon the time of year. 

This can affect what you store in your garage. While your options to improve the fabric of the building may be limited, you can reduce the humidity with a dehumidifier. 

In this article, I’ve summarized the best dehumidifiers available for small, large, or even commercial garages. Read on to find out more!

Benefits of a Garage Dehumidifier

A dehumidifier is a machine that removes moisture from the air, which helps to control the humidity levels, which can have many consequences for your garage (Source: Breathing Space). 

Reduce Metal Corrosion

Elevated humidity levels in poorly ventilated areas, like a garage, can accelerate metal corrosion, particularly on items such as gym equipment. By reducing the humidity of a garage, you can save your gym equipment from rust!

Improve Indoor Air Quality

Dehumidifiers can play a vital role in improving indoor air quality and health. Reducing humidity levels to less than 50% reduces environmental allergens such as dust mites (Source: Arlian et al, 2001). 

Dehumidifiers also create a more comfortable environment, especially for individuals with asthma aggravated by humidity, as they can ease symptoms by eliminating excess moisture from the air (Source: Live Science).

Minimize Mold and Mildew Development

The EPA recommends that indoor relative humidity be below 60%, ideally between 30% and 50%, if possible, to prevent mold growth (Source: EPA). 

Dehumidifiers help reduce mold and mildew growth, thereby reducing the risk of health issues and damage to property such as clothing and soft furnishings.

Prevent Pests 

Pests like dust mites, silverfish, and cockroaches thrive in humid conditions. 

Dehumidifiers make the environment less hospitable to these pests, reducing the likelihood of infestations (Source: Healthline).

How to Choose the Best Garage Dehumidifier

When choosing the best dehumidifier for you and your garage, consider some of the following points in your search.

Energy Star Rating

The Energy Star Rating indicates the dehumidifier’s energy efficiency, helping to save on electricity costs. Look for dehumidifiers with an Energy Star Rating to help save you money while it is in operation.

Moisture Removal Rate

Check the moisture removal rate, measured in pints per day (PPD), to ensure it will work with your garage size and humidity.

Drain Options

Consider the drain options available, such as manual emptying via a tank or whether there is a direct hose for continuous draining/installation into existing HVAC systems.

Square Foot Coverage

Measure the square footage of your garage and choose a dehumidifier that can handle that area effectively.

Noise

Consider the noise level of the dehumidifier, especially if you plan to spend time in the garage while it’s running.

Wattage

Check the power consumption of the dehumidifier to ensure it aligns with your energy capacity, as you don’t want to overload your circuit accidentally!

Portable vs. Permanent

Decide whether you need a portable dehumidifier that can be moved around or a permanent one fixed in a specific location, such as the Aprilaire E100

Size

Consider the unit’s physical dimensions to ensure it fits well in your garage without causing obstructions.

Cold Weather Tolerance

For colder climates, ensure the dehumidifier has cold weather tolerance, as coils freezing during winter can affect its performance. Also, check to see if the dehumidifier has a defrost setting, which can help performance.

FAQs

Why is my garage so humid?

Your garage can become humid due to various factors, such as a lack of proper ventilation, poor insulation, and water leaks. If you frequently use water-related equipment for washing cars, this can also contribute to higher humidity levels.

How does a garage dehumidifier work?

A garage dehumidifier pulls in humid air and passes it over cold coils. 

The moisture in the air condenses on these coils, turning into water droplets, which the dehumidifier collects in a water tank or drains through a hose. 

The dehumidifier then releases dry, moisture-free air into the garage (Source: How Stuff Works).

Where should I place my dehumidifier in my garage?

Place the dehumidifier in a central location in the garage to ensure even air circulation and efficient moisture removal. Avoid placing it near walls or obstructions that might obstruct airflow. 

If there are specific areas with higher humidity, like corners or near water sources, you can place the dehumidifier closer to these areas to help dry them out.

How often do I need to run my garage dehumidifier?

If you notice consistently high humidity, it’s best to run the dehumidifier continuously or set it to a timer that aligns with when you use the garage the most. 

Or you can run it for a few hours each day or as needed to maintain a comfortable humidity level. 
Monitoring the humidity levels using a hygrometer can help you decide when to run the dehumidifier.

Final Thoughts on Garage Dehumidifiers

Garage dehumidifiers play a crucial role in maintaining a dry and comfortable environment. 

Investing in a good quality garage dehumidifier can markedly improve a garage’s overall condition, protect your possessions, and contribute to a healthier and more comfortable environment. 

By reducing excess humidity, dehumidifiers can help prevent issues like mold growth, corrosion of metal items, and damage to belongings.
