After extracting water from carpets, moisture still remains in the affected areas. Think of it like your laundry - even though the spin cycle removes a lot of the moisture in the washing machine, you still put your clothes through the dryer. SERVPRO of Edison uses dehumidifiers and air movers to remove any remaining moisture to ensure that the home is healthy and dry.
In this photo, water came from the room above, so two air movers are aimed at the ceiling, one is drying the carpet and the dehumidifier works to reduce humidity in the entire room.
