The A/B Ratio in the context of dehumidification refers specifically to the ratio of airflow to dehumidifier output. Understanding this ratio is crucial in water damage restoration because it helps professionals assess the efficiency of the dehumidification process.

When restoring a water-damaged area, maintaining the right balance between the volume of air being moved (airflow) and the amount of moisture being removed (dehumidifier output) is important for optimizing drying times. A higher A/B ratio indicates efficient moisture removal relative to the airflow, which can lead to faster drying of the affected materials and spaces.

This concept is essential as it also impacts the overall moisture equilibrium within the environment. An improperly balanced ratio can lead to ineffective drying, potentially resulting in further moisture issues or mold growth. Therefore, focusing on this ratio allows restoration technicians to tailor their equipment and strategies more effectively during the drying process.
