Do you need a dehumidifier in your garage?

The answer is yes. You ultimately need a dehumidifier in your garage. Below we highlight for you the reasons as to why you should have one.

  • Improve indoor air quality

It is impossible to feel comfortable sitting in a garage with high humidity. This is because any environment full of humidity leads to the growth of mold and mildew. Excess mold can cause too many spores in the air. This becomes a problem for those who are sensitive to allergic mold spores. Inhaling them can cause allergic reactions, sneezing, runny nose and red eyes.  A dehumidifier will surely help you out of this mess. Dehumidifiers work by reducing moisture levels in the air by sacking excess water molecules. This helps stop mold as its development is supported by high levels of moisture. Afterwards, your air quality will be safe for everyone.  

  • Prevent mold and mildew growth

Mold and mildew commonly grow in moist environments. Garages commonly have moisture in the air. Most garages are dark inside, and have no windows. Such circumstances are ideal for the growth of mold. A dehumidifier will help you remove moisture from the garage. This will therefore limit the chances of mold or mildew growth.

  • Help protect your floor

When the floor is filled by high levels of moisture, its integrity gets compromised. It develops mold and mildew, which makes it displeasing.  It is actually worse when the floor is wooden. Excessive moisture can make the woods rot. A dehumidifier removes moisture that supports mold and mildew growth. This will help you protect your floor. 

  • Prevent the spread of flu viruses

A dehumidifier can prevent you from getting the flu in your garage. Humid conditions make it easier for flu viruses to transmit and live long. By using a dehumidifier you are minimizing the chances of influenza development. This is because moisture is removed and thus limiting the chances of the virus surviving. This thus reduces the possibility of contracting the flu.

  • Improved Respiratory health

High humidity can increase mucus in the nose and throat. Consequently, this causes sneezing, congestion, post-nasal drip and a runny nose. A dehumidifier will help you reduce humidity to the required level. This will help improve your overall respiratory health.

  • Protect maintenance equipment

Many people would like to keep their maintenance tools, especially metals in the garage. However, with high levels of humidity these might quite easily start to rust. This is because of  the reaction of water compounds making contact with them. A dehumidifier would help remove water molecules from the air to prevent it from reacting with the metal. 

  • Protect your car

The most important role of the garage is to keep the car safe. However, high humidity will significantly affect your car and different car parts that are prone to negative effects of high humidity. The engine, metal parts and leather seats will highly suffer from the effects of high humidity. A dehumidifier can help save you from the related maintenance and repair expenditure. It will always ensure minimum humidity levels in your garage. 

How to pick the best dehumidifier for garage

  • Coverage Capacity. Dehumidifiers come in different shapes and sizes, which determines their performance. When your garage is large, it means you will have to get a dehumidifier with an extended coverage capacity. However, it is not beneficial having a large capacity dehumidifier in a small garage. So, you have to assess the size of the garage in relation to coverage capacity of the dehumidifier. 
  • Bucket Size. You will not enjoy having to constantly empty your dehumidifier bucket. You need to look out for a dehumidifier with a tank that can hold a good amount of water. An average garage will require a dehumidifier with a bucket of at least 0.5 gallons.  
  • Auto defrost . The feature helps the dehumidifier coil not to freeze. This means your device will not stop operating because of freezing. A good dehumidifier for a garage needs to have an auto defrost feature. 
  • Auto Start/off. You may not always be around the garage, but moisture levels will continue to rise. You need a dehumidifier that will sense the rising humidity and automatically start up. When humidity levels drop to required levels, it will shut off immediately. 
  • Maximum moisture removal. The amount of moisture your dehumidifier sacks from air matters. Your garage will need a dehumidifier that removes a good amount of moisture. A garage dehumidifier should be able to remove at least 20 pints of moisture. 
  • Drain Options. In most cases, you may not be able to always drain the bucket as your garage is being dehumidified. You need a dehumidifier that will continuously operate all night. This is possible with a dehumidifier that offers various drain options. A dehumidifier with a drain hose, can help you drain the bucket continuously. This will thus help you to not frequently visit the garage to check the bucket. 

What size dehumidifier do I need for my garage?

Generally, it depends on the size of your garage. Depending on the garage size a 20-50 pint dehumidifier may be enough. The average size of a garage is between 1500-4500 square feet. 

Will a dehumidifier help cool a garage?

A dehumidifier removes moisture from the air, leaving the garage a bit cool and dry. Since the relative humidity is reduced, you can feel about 5 to 10 degrees cooler. But, dehumidifiers do not lower the actual temperature.

How do I get rid of humidity in my garage?

  • Ventilation

This is one of the simplest approaches of removing humidity in the garage. You need to open windows and doors to allow moisture escape. Besides, if you have an exhaust fan you can also put it in your garage. This can help you blow out the moisture leaving the room dry, thus getting rid of moisture.

  • Air conditioning

Air conditioner can help you get rid of humidity in your garage. Put on the air conditioner once in a while to allow air circulation to remove excess moisture.

  • Clean small water puddles in the garage

In most cases, water puddles in the garage are ignored, and are usually not drained. This is one of the primary causes for the increasing humidity in the garage. These puddles of water cause evaporation of water into the air. In that case, you need to dry up these puddles, and leave the garage floor dry.

  • Put a dehumidifier

Dehumidifiers play a significant role when it comes to getting rid of humidity. These work by sucking out water in the air to prevent condensation. This will help you minimize humidity levels in your garage.

  • Constant checks for drainage leaks

Drainage leaks can have a strong influence on the increasing moisture in your garage. These leaks make walls and floors wet, paving way for moisture development. When you conduct regular checks, you will be able to identify leakages before the situation worsens.

Can a dehumidifier work for low temperatures?

Dehumidifiers are designed to operate at temperatures above 65 degrees. If the temperature drops to less than 65 degrees, the evaporator coils can freeze resulting in motor burnout. However, there are several dehumidifiers that are able to work at low temperatures. These work by shutting down the compressor when the coils become cold, and restart when they are warm.

Will a dehumidifier work in a garage?

The answer to the question is yes. Humidifiers are designed to remove water in the air from open spaces, and a garage is no different. You only have to put it into the garage, and let it operate. It will help you get rid of moisture.
