Coverage varies depending on moisture levels.
Factors That Affect Coverage
A dehumidifier’s performance depends on:
Humidity
Extremely humid spaces require more capacity.
Ceiling Height
Higher ceilings increase the volume of air.
Temperature
Warm air holds more moisture.
Airflow
Open floor plans allow better circulation.
Insulation
Poor insulation can increase humidity.
