Saves money.[1][2] Zero greenhouse gas emissions per load[1][2] (2 kg CO2eq of greenhouse gas emissions from the average mechanical clothes dryer per load).[3] Less fabric wear and tear.[2] Laundry items do not shrink (hot air from a mechanical clothes dryer may shrink items). No static cling and no perfume smells throughout the neighborhood from fabric softener and anti-static dryer sheets. Laundry items stay softer to the touch (mechanical clothes dryers tend to remove short, soft, fine fibers), and may be less wrinkled.
