Mold loves moisture. The number one tool in fighting mold is good ventilation. After you take that shower, turn on the bathroom fan. While you’re cooking your mother’s recipe for spaghetti sauce (the one that needs to simmer all day), turn on the fan over the stove.
Open the windows to keep air circulating. Turn off the air conditioner; turn on the dehumidifier. You need to prevent any condition that causes condensation of moisture, which mold loves.
Check for leaks around your plumbing. Make sure that water from the outside doesn’t make it inside. Prevent wetness from collecting anywhere.
Mold feeds on dust. So, vacuum regularly. Get your home’s ducts cleaned regularly by a professional with the right tools to do the job.
Have your HVAC system professionally cleaned. Regular maintenance not only helps keep mold away, but it also contributes to other factors of indoor air quality.
