Dehumidification reduces the _____ content of the air.

Dehumidification is a process specifically aimed at lowering the moisture content in the air, which is crucial in water damage restoration. When water is introduced into a structure—through flooding, leaks, or high humidity—the air can become saturated with moisture. By using dehumidifiers, the excess moisture is removed from the air, reducing the relative humidity levels. This not only helps to promote the drying of wet materials but also prevents the growth of mold and mildew, which thrive in moist conditions. Therefore, the process of dehumidification directly targets moisture content, making it the correct answer in this context.
