Best Garage Dehumidifiers Buyer’s Guide

Coverage area

This is the most important factor to consider when investing in a garage dehumidifier. The size of the room is the main factor that will determine what size dehumidifier you will need. The capacity of the dehumidifier is how much moisture it can collect and is generally measured in pints. 

A larger garage will naturally need a dehumidifier with a larger capacity. Using one with too little capacity for the room is fairly ineffective.  

Garage conditions 

Some garages contain more moisture than others and this also needs to be factored in when deciding on the ideal capacity dehumidifier. If you have leaks or an underground garage you might need a larger unit than just the coverage area suggests. 

Other factors that will come into play are the number of occupants in the garage and if you have a washer and/or dryer in the garage. These increase the humidity and call for a larger dehumidifier.  

Drainage

The way that a dehumidifier works cause water to accumulate and this needs to be removed. There are two ways this can be done.

The first is a manual system where you need to remove the tank that collects the water and empty it out. Some are well designed and make this task quick and easy. With some, it can be more of a challenge. 

The other drainage system uses a hose to continuously drain water as necessary. The hose is normally an extra but it is a standard hose that you either have or is inexpensive to purchase. This requires a bit of installation but that is simple and the result is very convenient. Most larger systems give you a choice of manual or continuous drainage. 

Energy Efficiency

You do not want to spend a fortune to run the device so the more energy efficient it is the less it will cost you on an ongoing basis. One that is not efficient can use a significant amount of electricity and costs can add up over time. 

A good sign that your dehumidifier is efficient is Energy Star certification. Apart from saving on your electricity bill a more efficient unit is also more eco-friendly. 

Durability

A dehumidifier works hard and a poor quality device will not last long. One that is well made from decent materials should last a fair while. 

Look at the reviews, the history of the company that makes them as well as the materials that are used. Also, look at the warranty to see how the company stands behind the product. 

Generally, the highly durable units are more expensive but then they last longer. 

Price

Following on from the above, price is a factor in your decision. More power, more features, a better design, and a longer lifespan normally mean a higher price tag. 

Having said that, there are several models that offer great value for money. They are fairly priced, perform well, and last a decent number of years. 

Low-temperature performance 

Many dehumidifiers do not work in extremely low temperatures. As garages are already cold spaces, this could be a problem if you live in a cold area. 

If this is a concern check on the operating temperature it can handle. The better ones can still function in temperatures down to  33 degrees Fahrenheit. 

FAQs

Why are dehumidifiers measured in pints? 

This refers to the capacity of water they can hold. A large garage will need a unit that can hold more pints.

What are the benefits of a garage dehumidifier?

A dehumidifier will remove moisture and humidity from the room. The decent ones also remove allergens and odors. These are all common issues in a garage. They are not good for the people that use the garage as well as the objects inside. 

A good dehumidifier will make the area safer, reduce the risk of mold, and protect the valuable belongings stored in the area. It also reduces the risk of corrosion so metal objects are less likely to be damaged by rust. This includes tools, equipment, and your cars. 

Are dehumidifiers expensive to run?

The larger units do draw a fair amount of power so this can be a concern. Ensure you get the correct size according to the size of the room and clean and empty it often. Look for one that is energy efficient. A sure indication that the dehumidifier is efficient is Energy Star Certification. 

How does a dehumidifier work?

While there different technologies, most work on a heat pump system. These work in a similar fashion to an air-conditioner. A fan pulls air into the device through a filter that collects airborne dust and debris. 

The air is then drawn over evaporator coils. Air moisture condenses on the cold coils and this water gradually drips off into the collection tray. 

Are there different types of garage dehumidifiers? 

Yes, there are three main types. The heat pump system described above is the most common. They are effective, efficient, and value for money.  A ventilator-style dehumidifier uses air exchange to remove air moisture. The “old” air is fed outside the building. This makes them a bit more difficult to install. 

The other type is a desiccant dehumidifier. These use chemicals that draw and contain moisture. Silica is a good example. They are generally disposable products that work in a confined space although you do get larger ones that have fans and can be recharged.   

Is it difficult and expensive to install continuous drainage? 

No, it could not be easier. Provided your dehumidifier has this option, all you need is a hose. This is often a standard garden hose or similar. Normally you will have something already if not, you can buy them for a few dollars. They are not expensive. 

All you need then is a way to get it to a suitable area outside. It requires no special skills or tools to connect and run the hose. Having this system will make your life a whole lot easier.
