The fan dried the towels first. The room hit 80% humidity.

When the drying rack is beside the bed in a 1K, the wash can dry pretty quickly and still make the room damp. In a 20°C test at Hokkaido’s consumer center, three cotton bath towels went through a seven-minute spin. A fan on medium got them dry in four hours. The dehumidifier took another half hour. In the fan tests, room humidity rose from 65% to 80% or higher in about two hours. With the dehumidifier running, it was mostly at or below 50%. The dehumidifier puts the water in a tank you can empty. An exhaust vent can carry it outside as damp air. In one windowless rental bath with a regular exhaust fan, the vent alone left the laundry wet. With the vent on high and a circulator blowing across the clothes, most pieces were nearly dry after four hours. The thick cotton knit took seven to dry through.
