Yes — under the right conditions, a dehumidifier can absolutely help dry clothes indoors. According to the makers of home appliances like Mitsubishi Electric, using a dehumidifier with a “Laundry Mode” can allow clothes to dry faster than simple air-drying inside a room.
Here’s how it works: the unit pulls moist air from the room, passes it through cold coils (or a desiccant) so water condenses out, collects the water, and then re-releases drier (and often slightly warmer) air. That dry air helps water evaporate from your wet clothes faster than if they were hanging in a humid environment.
But — heads up — a dehumidifier won’t match the raw speed of a tumble dryer. Some loads may still take several hours to dry completely, especially heavier fabrics like jeans or thick towels.
Still, many people find the trade-off worthwhile: gentler on clothes, more energy efficient than a standard dryer, and often more reliable than waiting for good weather.
