Una boquilla perfeccionada, esencialmente caracterizada por un filtro de un material poroso o absorbente en el interior de una cápsula cilíndrica, la cual se continua por un tubo de material plástico o similar que se aloja en el interior del conducto del cuerpo de la boquilla, terminando en la embocadura de la misma, de manera que los humos están obligados a pasar por el interior de dicho tubo complementa rio del filtro, evitando así que se ensucie el conducto de la boquilla.
