A dehumidifier should primarily be placed in the basement (or lowest, most damp area) to combat moisture at its source. Basements often suffer from high humidity and poor ventilation, and up to 50% of the air on your first floor originates from the basement. Placing it centrally in the basement ensures optimal performance.
