When you notice a musty smell or see dark spots on walls, mold air sampling can identify what you're breathing. A special pump pulls a measured amount of air through a cassette that captures invisible spores, which a lab then analyzes. This process is more thorough than simply searching for visible growth because it detects airborne mold that can trigger allergies or asthma without obvious signs. It is a good way to figure out if you have a hidden problem or if the air quality has worsened.
