Abstract
"Una nueva careta contra el polvo", caracterizada por que está constituida esencialmente por una mascarilla que se aplica a la nariz y boca del usuario, el cual al aspirar, absorbe el aire a través de una gamuza, mientras que la espiración se efectúa por conducto distinto, debido a la acción de una válvula prevista para este fin de tal manera que la gamuza permanece siempre seca y permite el fácil paso del aire.
