The revolutionary design of the Split Screen Pop Filter ensures superior performance! Air Pressure Dispersion Technology (A.P.D.T.) provides the optimal amount of space between two engineered screens to eliminate all unwanted explosive 'P' and 'B' consonants better than traditional style pop filters. The first screen diffuses the air that causes explosive consonants. The open space between the screens disperses air pressure that can build in hoop style pop filters, while the second screen removes any remaining explosive consonants.
