High velocity air movers are used during which phase of moisture removal?

High velocity air movers play a crucial role during the drying phase of moisture removal. Their primary function is to increase air circulation and promote rapid evaporation of moisture from affected surfaces. By creating a strong airflow, these devices help to lower the relative humidity in the environment, thereby facilitating the drying process more effectively.

Using high velocity air movers during this phase assists in minimizing the potential for mold growth and structural damage by expediting the removal of moisture. This is essential in restoration and remediation practices, where time is critical to prevent further deterioration.

In contrast, the other choices do not align with the specific function of high velocity air movers. For instance, using them before cleaning does not address moisture removal, as the primary focus at that time would be preparing the site for cleaning. After completion of drying, their role is diminished, as the moisture issue has already been resolved; thus, continued use for this purpose would be unnecessary. Lastly, air quality monitoring is focused on assessing the indoor environment and does not involve the active drying of materials, which further highlights the role of air movers specifically during the drying phase.
