Mold is a type of fungus that grows in damp environments and can release spores into indoor air, potentially causing respiratory issues and allergic reactions. Mold thrives in moisture levels above 60% relative humidity and temperatures between 60-80 degrees Fahrenheit. Common indoor mold types include Aspergillus, Penicillium, and Stachybotrys.
Growth Conditions and Detection
Mold requires three key conditions: moisture, organic material, and darkness. It commonly appears in bathrooms, basements, crawl spaces, and around HVAC systems with condensation problems. Visual inspection may reveal black, green, or white spots on surfaces, while a musty odor often indicates hidden mold colonies.
Health Impact and Control
Mold spores can trigger asthma attacks, allergic reactions, and respiratory infections in sensitive individuals. Control involves reducing indoor humidity to below 50%, improving ventilation, fixing water leaks promptly, and using dehumidifiers in problem areas. HVAC systems should include proper drainage and regular filter changes to prevent mold propagation through ductwork.
