What should indoor humidity generally be maintained at?

• A. 10-30 percent
• B. 20-60 percent
• C. 30-80 percent
• D. 40-70 percent

Answer: (B)

Indoor humidity is important for maintaining comfort and health within indoor environments. A general recommendation is to maintain indoor humidity levels between 20 to 60 percent. This range helps prevent conditions that can lead to the growth of mold and dust mites, which thrive in higher humidity levels, while also minimizing the discomfort associated with very low humidity, such as dry skin and respiratory issues. Keeping humidity within this range does not lead to condensation on windows or other surfaces, which can be problematic in terms of building maintenance and indoor air quality. It also enhances comfort for occupants, as excessively low or high humidity can lead to discomfort and health problems. Therefore, the recommendation for indoor humidity levels is rightly positioned at 20-60 percent as it strikes a balance that promotes both health and comfort within living and working spaces.
