What is the potential effect of high humidity on indoor air quality?

High humidity can significantly impact indoor air quality, and its potential effect includes promoting the growth of allergens and pollutants. When humidity levels are elevated, typically above 60%, it creates an environment conducive to the proliferation of various biological contaminants such as mold and dust mites. These organisms thrive in damp conditions, and their presence can exacerbate respiratory issues, allergic reactions, and overall discomfort among inhabitants.

In addition, high humidity can lead to the accumulation of moisture on surfaces, which may also contribute to the deterioration of building materials and promote the presence of indoor pollutants like bacteria. Overall, maintaining an appropriate humidity level is crucial for fostering healthy indoor air quality and preventing the harmful effects associated with excessive moisture.
