A method of purifying a thermoplastic polymer having at least one dispersed filler, including preparing a polymer melt of the thermoplastic polymer, and filtering the polymer melt, where the dispersed filler is at least partially transformed to a coagulated and filterable form before the filtering step. Also, a device for purifying the thermoplastic polymer, including means for preparing a polymer melt from the thermoplastic polymer, and filter means, and means for generating sound waves, preferably ultrasonic waves.
