What is the generally accepted mold spore level in indoor air?

The generally accepted mold spore level in indoor air is typically considered to be less than 200 spores per cubic meter. This threshold is based on studies and guidelines that aim to ensure indoor environments are healthy and do not pose risks to occupants' health. Levels above this can indicate potential mold problems, suggesting conditions conducive to growth or the presence of dampness or moisture issues.

Understanding this standard is critical for mold assessors when evaluating indoor air quality. It helps them identify environments that may require further investigation or remediation. While some other thresholds exist for different conditions, 200 spores per cubic meter serves as a commonly referenced limit in many assessments and studies, denoting a level that is generally safe for most indoor environments.
