Quick Fixes to Reduce Humidity Immediately

If you’re dealing with moisture problems and need to lower humidity in your home quickly, there are a few quick measures you can take. The following are not long-term solutions, but they can help reduce the humidity in your home effectively.

One easy way to reduce moisture inside your home is to use a dehumidifier.

Tips:

• Don’t open windows when it’s humid out, since that can make matters worse.

Long-Term Solutions to Lower Humidity

Quick fixes may help, but real control of humidity is best obtained by more aggressive, long-term methods. These steps address issues the excess humidity, resulting in year-round, reliable moisture management.

Common Mistakes When Trying to Lower Humidity

Moisture management methods are not equally effective. Many homeowners make mistakes that worsen the situation.  From over-relying on air conditioning to overlooking hidden sources of humidity,  knowing what not to do is as important as knowing what to do. 

Overusing Air Conditioning vs. Proper Dehumidification

AC systems do remove some moisture, but they’re not a solution to target specific humidity control.

 There are hidden sources of moisture that we tend to ignore.

• Unprotected crawl spaces allow for in-ground moisture.
• Indoor clothes drying can introduce gallons of water into the air.
