Your Basement may also contain these air quality hazards:
Radon Gas
Radon is the #2 cause of lung cancer after smoking. It seeps from soil into basements and crawl spaces. You cannot see, smell, or taste it. The only way to know is to test.
Mold Exposure
Mold releases spores that trigger allergies, asthma attacks, and respiratory infections. Black mold (Stachybotrys chartarum) produces mycotoxins linked to neurological symptoms.
Asbestos Fibers
Asbestos causes mesothelioma, lung cancer, and asbestosis. Homes built before 1980 likely contain asbestos in insulation, floor tiles, and pipe wrapping. Disturbing it releases deadly fibers into the air.
High Indoor Humidity
Humidity above 60% creates ideal conditions for mold, dust mites, and bacteria. It also increases off-gassing of VOCs from furniture and building materials. The EPA recommends 30-50% indoor humidity.
Basement Air Quality Hazards
Basements accumulate the worst indoor air hazards: radon, mold, chemical storage fumes, and pest allergens. Because warm air rises, basement pollutants circulate throughout the entire home through the stack effect.
