Abstract

"FILTRO RESPIRADOR APRESENTANDO UMA CAMADA DE FILTRO CORRUGADO", compreendendo um meio de filtro (20) da presente invenção que inclui uma camada de filtro corrugado (22) e uma camada de filtro liso (24) adjacentes à camada de filtro corrugado. Tanto a camada de filtro corrugado quanto a camada de filtro liso pode conter um material termoplástico permitindo que as camadas de filtro se unam usando solda ultra-sónica ou selagem térmica, facilitando sua fabricação. O meio de filtro (20) apresenta uma pequena altura que o torna apropriado para ser usado em respiradores de dobra lisa e filtros lisos.
