Air and surface sample analyses typically reveal a diverse range of fungal spores. A spectrum of fungal species is commonly found both indoors and outdoors. Acceptable levels vary based on the specific types detected, their concentration, and the overall context of the environment being tested. For example, the presence of certain species indoors at higher concentrations than outdoors may indicate an indoor mold source.
Understanding background levels of airborne fungal spores is critical for accurate interpretation of indoor air quality assessments. Comparing indoor samples to established baselines helps determine if elevated levels of specific molds exist, signaling potential issues like hidden moisture problems or compromised building materials. This information empowers informed decisions regarding necessary remediation actions and can ultimately protect the health and well-being of occupants.
