Fixing leaks or water damage promptly can help prevent mold growth by eliminating the source of moisture.
Can maintaining a humidity below 45% effectively prevent mold growth?
Maintaining a humidity below 45% can effectively prevent mold growth, but it may not be necessary in all cases. The ideal range for indoor humidity levels is between 30-60%, with the best range being 35-45%. While maintaining humidity levels below 45% can help prevent mold growth, it may not be necessary if other strategies, such as proper ventilation and fixing leaks, are used to manage indoor humidity levels.
What are the health risks associated with mold caused by excessive humidity?
Excessive humidity can lead to mold growth, which can cause a variety of health problems, especially for individuals with allergies or respiratory issues. Exposure to mold can cause symptoms such as nasal congestion, coughing, wheezing, and eye irritation. In some cases, exposure to mold can cause more severe health problems, such as asthma attacks or allergic reactions. It is important to manage indoor humidity levels to prevent mold growth and reduce the risk of health problems associated with mold exposure.
