Mold Count by State 2025

Mold counts across different states provide valuable insights into regional environmental conditions and their potential impact on public health. Mold, a common allergen, thrives in various settings, and its prevalence fluctuates based on factors such as climate, geography, and seasonal variations.

States like Kansas, New York, and New Jersey consistently report higher mold counts, reflecting a combination of factors such as humidity levels, temperature fluctuations, and urban development. These states often experience elevated mold levels, especially during warmer months or in densely populated areas where moisture accumulation and poor ventilation contribute to mold growth.

On the other hand, states with lower mold counts, such as Washington, Nevada, and Hawaii, benefit from drier climates and natural barriers that inhibit mold proliferation. The arid conditions in these regions mitigate mold growth, offering residents relief from potential health concerns associated with mold exposure.

It’s important to note that mold counts within every state vary greatly by season, location, and microclimate. Factors like rainfall patterns, proximity to bodies of water, and indoor air quality also influence mold levels, highlighting the need for localized monitoring and mitigation strategies.
