This picture was taken at a recent video shoot of company owner John Baldwin describing how this piece of equipment works. If SERVPRO of Roanoke Rapids has ever been in your home after a fire, than you've seen our air scrubber. This piece of equipment is more appropriately referred to by professionals as an "air filtration device," or AFD. Simply put, this devices filters airborne particles out of the air, giving you cleaner air to breathe. The machines are used on many types of jobs, but we use them after a fire since there is soot in the air. This device traps airborne particles in their filters, allowing filtered air to pass through the machine and re-enter the breathing environment cleaner.
