A dehumidifier can help solve many air quality issues in your home that are attributable to humidity. Humidity can promote the growth of airborne allergens such as mold spores and dust mites.

Should I put a dehumidifier in my garage? Yes, you should put a dehumidifier in a garage because most garages tend to have high humidity levels as they are not well-ventilated. Dehumidifiers will remove humidity from the air reducing the potential for dust mites, mildew, and mold inside the garage.

Relative humidity can have adverse effects on the air you breathe when levels exceed 50%. At these levels, allergens are far more likely to worsen the overall air quality. Excessive humidity can also cause problems with the structural integrity of your home, the condition of your home furnishings and create an unpleasant musty odor

For the air in your home to feel cool, it must be dry. Humid air can cause your AC unit to overwork itself and raise your utility bills unnecessarily. When dry air is maintained, not only does it help to eliminate these issues, but it also creates a healthier breathing environment.

Do Dehumidifiers Work in Garages?

Dehumidifiers are an essential part of every home. They keep the air inside your house dry and comfortable. However, dehumidifiers aren’t always effective at keeping the air inside your garage dry.

If you’ve ever tried to store anything in there, you know how quickly it gets moldy. Humidity in the air prevents sweat from evaporating. So, a humid day feels hotter to us than a less humid day that’s at the same temperature.

If you can find ways to reduce the relative humidity levels, it can make the temperature feel five to ten degrees cooler than it really is. When you‘re working in your garage during the middle of the day during the summer months, ten degrees cooler can mean the difference between being comfortable and feeling miserable.

How to Identify If Your Garage Has Humidity Issues

If you smell a musty, stale odor in your garage, it may be due to excessive moisture levels in the air.

Paint peeling off of walls is another sign of high moisture levels in a garage, especially if you have sheetrock walls. This is more evident if you have engineered some hardwood siding installed inside your garage. In such cases,  you should especially check the lower corners for any signs of peeling and deterioration.

Additionally, if you notice paint peeling off of walls, this is a sign of high moisture levels inside your garage. You may also notice water stains on the ceiling. These are signs of water damage caused by leaks in your roof.

Finally, the presence of mold is another sign that you should install a dehumidifier in your garage. Mold is a fungus that grows on damp surfaces. Mold can be found in many places including basements, garages, bathrooms, kitchens, crawl spaces, attics, and other areas where moisture collects. Mold can cause health problems if it gets into your lungs or nose. Mold also causes structural damage to homes and buildings.

You can prevent mold growth by keeping the area dry. However, if you notice water spots on your garage walls, then there could be other reasons for the problem.

Reasons For Moisture In a Garage

A garage is designed to be a place to store things. It is not designed to be a place for people to live. Due to this, most garages lack any form of proper ventilation in place. Essentially, without the large garage doors, it is basically a cave with o free flow of air.

If you don’t have a way for humidity to escape, moisture builds up on floors and walls over time. When not mitigated on time, the buildup of moisture can cause serious damage to wood flooring and drywall.

Generally, there are three primary methods of identifying the presence of moisture in a garage; condensation on the floor, standing water on the floor, or in a later stage, evidence of mold of the wood on the walls and ceiling of the garage.

Why Do You Need a Dehumidifier

Air pollution very heavily affects not only our respiratory system but also our heart. So it’s important to at least maintain fresh air in our homes. Due to excessive moisture, houses can start getting dust mites or mold which is extremely dangerous to the human respiratory system and overall health.

Suitable environments should not cause discomfort. You should not feel headaches, have a dry cough or have itchy eyes. The rooms or the walls should not contain black spots, and if they appear you can suspect that something is wrong with their microclimate.

Moisture is most commonly seen while dryness is usually felt. Conditions that dry out our nose and throat, unstoppable viruses and bacteria enter the airways easier and can even cause allergies. They can also cause rash itchy skin, and if the person has a chronic disease such as asthma dryness can cause it’s more frequent attacks.

A dehumidifier is what you need. Taking excess humidity from the air, the collector condenses it and collects it in a tank and later the condensate is discarded. This helps to drop the relative humidity. Enjoy fresh air for better health.

 

Which dehumidifier is right for your garage?

  • Excess humidity can become a serious issue if not addressed and we have selected the best performing units in all categories to ensure that you will find the one that fits your specific team edification needs. Check out our list of the best dehumidifiers for your garage.
  • Home dehumidifiers come in varying pint-sized capacity which correlates to the square footage and moisture level of this space you will be using the unit in. Most units allow you to set your desired level of humidity and will automatically turn on and off as needed.
  • While the physical size of the unit might be similar, there can be a big difference in the amount of water the unit can remove from the air per day. The larger the pint-sized capacity, the more efficient it will be and the quieter it will be.
  • Both at-home dehumidifiers feature a water bucket and automatic shut-off feature for when the container is full. Many models are also equipped with a drain hose connection that allows for continuous drainage when required.
  • If you need to use the unit in a space where the ambient temperature could drop below 65 degrees Fahrenheit, you will need to purchase a low temp unit such as those offered by both Danby and Edge Star.
  • Garage dehumidifiers are generally more rugged in design. They are made to operate in low temperatures and some come with drain pumps for permanent installation.

How to Choose the Best Dehumidifier

Dehumidifiers are used to remove moisture from the air. They are often used in basements, bathrooms, kitchens, garages, and other areas where there is excess humidity.

There are two main types of dehumidifiers: portable and stationary. Portable dehumidifiers are small units that can be moved around the house. Stationary dehumidifiers are large units that are usually installed in the basement or garage.

When choosing a dehumidifier, consider these factors:

Size

Think about the size of your space and the capacity you’ll need. Dehumidifiers are rated by the number of pints of moisture they can remove in 24 hours. A small unit works great for a smaller room with lower level humidity. Larger models are best for basements and high humidity environments especially if wet carpet, wallpaper, or musty smells are present.

Placement.

Units typically take up a square foot of floor space. Keep the filter clean and vents clear with at least 12 inches of circulation space. Also, consider noise level if you plan to run the unit in common areas.

Built-in features

If you plan to be away frequently, choose a model with a timer and an auto-restart in case of power failure. If you plan on moving the unit around, choose rolling casters.

Energy Star ratings

Dehumidifiers with an Energy Star rating used nearly 30% less energy than non-certified units. They may cost more initially but make up for it and energy savings over time.

External hose connector

Most models have an indicator showing when the bucket is full. To avoid emptying the tank manually, choose a model with an external hose connector. Some models advance this idea with an added internal pump that automatically pumps water upward up to 16 feet out a window or into a utility sink or drain.

Advantages of a Dehumidifier for a Garage

Dehumidifiers have become integral in garages and homes today. But did you know that there are other benefits to having a dehumidifier in your garage? Here are some of the advantages of having a dehumidifier in your garage.

1. It helps keep your home cool

When you have a dehumidifier running in your garage, it will help keep your home cooler. This means that you won’t have to turn on the air conditioner as often.

2. It helps Prevent Mold Growth

Mold and mildews grow in damp environments, such as the garage. Most garages and dark and have no windows. The location and natural environment of the garage encourage moisture which leads to the growth of molds.

A humidifier can help to drive out moisture and humidity from the garage. When this happens, the chances of growth and development of mold and mildew are greatly reduced.

3. Better Indoor Air Quality

A humid garage feels hot and stuffy. It is impossible to live or work in a garage with high moisture content. This is where a dehumidifier comes in. It goes a long way in helping you improve the indoor air quality in your garage by removing moisture from the air. When the air is hot and dry, it holds any pollutants present e.g. dust mites and pollen.

4. Protect Garage Walls and Floor

A dehumidifier can be used to help protect the garage walls and floors. When the floor and walls of the garage are wet, the integrity of the entire structure is compromised. If you use wood, the dampness will cause the structure to rot and get weak. Using a dehumidifier will dry the walls and floor and prevent this decay from taking place.

Conclusion:

It is no doubt, a dehumidifier comes with numerous benefits. If you live in places that have high humidity, you may need to get one not just for your overall health, but to protect the tools inside your garage and also prevents the garage from smelling bad.
