Why Humidity Level Is Important

If you live in humid areas with inclement weather conditions, you will likely experience a lot of humidity fluctuations in your garage.

During the cold weather months, humidity can go as high as 80-90%.

Freezing temperatures coupled with a lot of rainfall mean that a lot of vapors will be trapped in the air. This is a great concern for your garage as too much humidity enhances rusting.

In most cases, the garage has very poor air circulation; hence a lot of moisture is trapped inside in these humid conditions rusting kicks in, which is a big deal for your metallic equipment that is prone to rust.

It is time-consuming and expensive to restore rusted metals.

If left unattended, rusting can weaken the metal parts of your precious equipment. This damage will affect the function and safety of your vehicle or equipment.

Damp conditions not only cause problems with rust but will also support the growth of molds and, consequently, the development of mildew in your garage.

The molds and mildew will make your garage smelly and unpleasant. Molds can also cause many health effects. Exposure to spores can cause a stuffy nose, sore throat, and even severe allergic reactions.

So, if you know the humidity level in your garage, you can take corrective steps to adjust the moisture level to the ideal level using a dehumidifier.

Five Causes Of High Humidity in Your Garage

There are plenty of possible sources of moisture in your garage. Consider the following causes:
