Abstract

"FILTRO MICROBICIDA DE AR PARA USO COM UMA PASSAGEM DE AR E MáSCARA FACIAL". Filtro microbicida de ar (10) para uso com uma passagem de ar, o qual compreende uma rede de imobilização (12) tendo substancialmente impregnada nela uma quantidade de pelo menos uma substância antimicrobiana suficiente para substancialmente imobilizar, reter e matar micróbios suspensos em um volume de ar movendo-se através da passagem de ar. A rede de imobilização (12) é substancialmente permeável ao ar. Uma máscara facial microbicida (24) e um filtro microbicida de ar (10) usado em um sistema de circulação de ar (40) usando a rede de imobilização (12) são divulgados.
