Mold Prevention Starts with Moisture Control: Why Every Midwest Home Needs a Dehumidifier
In the Midwest — especially in states like Michigan and Ohio — seasonal humidity spikes can create ideal conditions for mold growth. Basements and crawlspaces are particularly vulnerable, and excess moisture can quickly lead to poor indoor air quality, structural damage, and health concerns. At MoldPro LLC, we specialize in helping homeowners and businesses protect their spaces, and one of the most effective first steps is using a high-quality dehumidifier.
Why Moisture Control Matters in the Midwest, Michigan, and Ohio
Scientific research confirms that mold requires sustained relative humidity levels above 50% to grow, with optimal conditions often found between 60–80%. By maintaining indoor humidity closer to 40%, you create an environment that is inhospitable to mold spores — effectively preventing their ability to colonize and spread.
Beyond mold prevention, excess humidity also promotes dust mite populations and can increase off-gassing of volatile organic compounds (VOCs) from building materials. These factors can significantly impact indoor air quality, particularly for individuals with allergies or respiratory sensitivities.
Where to Use a Dehumidifier
Basements:
In Michigan and Ohio, basements often experience high humidity due to their below-ground placement and limited airflow. This makes them top candidates for dehumidifier use.
Crawlspaces:
For homes without basements, crawlspaces are the next concern. These areas are frequently exposed to ground moisture and poor ventilation.
Other Areas:
If your home lacks both a basement and a crawlspace, and you don’t notice signs of excess moisture — like condensation, musty odors, or damp materials — a dehumidifier may not be necessary. However, regular humidity monitoring with a hygrometer remains essential for maintaining a healthy indoor environment.
Choosing the Right Dehumidifier
Match the dehumidifier’s capacity with the size of the space. Most models list their coverage in square footage, making it easy to compare with your basement or crawlspace.

Dehumidifier Sizing Calculator
For large basements or areas prone to frequent flooding, consider a commercial-grade or crawlspace-specific dehumidifier equipped with a hygrometer and built-in humidistat. These provide more precise moisture control and are built for continuous operation.
Important tip: Choose a unit with a drain hose or built-in pump to avoid daily maintenance. Place the unit at least 25 feet away from the sump pump crock to prevent it from recycling moist air from the sump, which compromises performance—a surprisingly common issue we see in Ohio and Michigan homes.
If you’re unsure whether a dehumidifier is the right solution for your space, a professional humidity assessment by MoldPro can help identify moisture sources and recommend tailored solutions.
When to Use It
We recommend running your dehumidifier from St. Patrick’s Day through Thanksgiving Day. This covers the months when Midwest humidity levels are typically highest, especially in Michigan and Ohio.
Where to Buy a Dehumidifier
You can find quality dehumidifiers at big-box stores like Home Depot, Lowe’s, Menards, and Walmart. Expect to spend a few hundred dollars for a reliable model that meets the needs of most Michigan and Ohio basements.
Trusted Brands
Brands such as Frigidaire, Honeywell, and hOmeLabs are well-rated for efficiency, durability, and ease of use. Look for Energy Star-certified models to reduce energy costs while supporting environmental responsibility.
