Here in Minnesota, we don’t have the most humid or arid climate in the country, but that doesn’t mean you don’t need to pay attention to the relative humidity level inside your home. Indoor relative humidity that’s outside the EPA’s recommended range can affect the way your HVAC system performs, cause health issues, and even diminish your indoor air quality. As such, it’s important to address indoor moisture levels that are outside that recommended range.

Read on to learn what you need to know about indoor relative humidity and why it’s important to keep tabs on.

What’s the Appropriate Indoor Humidity Range?

First and foremost, you should know what an appropriate ambient moisture level is for your home. According to the Environmental Protection Agency, relative indoor humidity (RH) should fall between 30%-50%, regardless of the time of year. An RH level of up to 60% is fine, but anything above that can diminish your indoor air quality and potentially cause health issues. The same idea applies when levels are below 30%.

How Do You Know if Your Humidity Is Too High or Low?

If you don’t have a humidity monitor on your thermostat or somewhere else in your home, it can be a little tough to tell whether your RH is out of range. That said, a few of the signs you might notice include:

●        High humidity. Mold, mildew, pest infestations, rotting wood, musty odor, and thick, heavy-feeling indoor air

●        Low humidity. Dry skin, dry nose, dry eyes, breathing issues, and dehydrated wood that may even crack due to lack of moisture

Since mold, mildew, pests, and wood rot can negatively affect your indoor air quality, if you notice these issues, it’s imperative that you address them promptly. Sensitive individuals may suffer respiratory problems, skin rashes, and allergies when indoor moisture levels are too high.

How Can You Control Indoor Humidity?

If you have a central a/c system, it’s designed to remove excess moisture from your indoor air as it recirculates that air through the system. But if you don’t get your a/c unit professionally cleaned on a routine basis, it may not be able to perform that job adequately. Scheduling a/c cleaning once a year is an excellent way to help ensure your HVAC system can effectively control indoor moisture levels.

If the air in your home is chronically dry, implementing humidifiers in various rooms around your house can make a big difference. Just make sure you monitor RH levels closely if you decide to use humidifiers so ambient moisture doesn’t get out of control.

If you think your home is suffering from poor indoor air quality due to prolonged low or high RH levels, it’s also a good idea to implement an air purification system to help clean up the air. Professional duct cleaning can also help. A thorough cleaning will remove debris and other allergy-triggering particulate matter that your duct system may be forcing into the air inside your home.
