Abstract

"FILTRO, RESPIRADOR, E, MéTODO PARA REMOVER SóLIDO PARTICULADO OU AEROSSOL LìQUIDO DE UM GáS". Um filtro que inclui uma primeira camada de filtro de eletreto através da qual uma corrente de ar passa primeiro antes de encontrar uma segunda camada de filtro de eletreto. A primeira camada de filtro de eletreto apresenta eficiência de remoção não decrescente e remove a maior parte de um aerossol testador; enquanto a segunda camada de filtro de eletreto apresenta eficiência de remoção decrescente e possui um fator de qualidade inicial maior do que a primeira camada. Juntas, as primeira e segunda camadas de filtro de eletreto podem prover um filtro que apresenta uma eficiência de remoção não decrescente e uma queda de pressão relativamente baixa. Este filtro pode prover eficiência de remoção não decrescente e reduzida queda de pressão muito embora a segunda camada de filtro de eletreto apresente eficiência de remoção decrescente em contraste com a desejada eficiência de remoção não decrescente para o filtro como um todo.
