Abstract
Se refiere a un dispositivo de filtracion que incluye un alojamiento impermeable al fluido que tiene una entrada y salida de gas, y que contiene dentro del alojamientos primeras particulas de medios de filtro de un sustrato de area de superficie ampliada y que contiene al menos un agente de impregnacion de metal, y segundas particulas de medios de filtro de un sustrato de hidroxido de zirconio de area de superficie ampliada y que contiene hidroxido de zinc. Las primeras o segundas particulas de medios de filtro tambien contienen un material con funcionalidad amina. El dispositivo puede usarse en atmosferas que contienen diversos gases perjudiciales, y puede proporcionar mejoras particularmente utiles en tiempos de paso para dioxido de nitrogeno, sulfuro de hidrogeno, amoniaco y formaldehido comparado con un dispositivo que contiene solo las primeras particulas de medios de filtro o solo las segundas particulas de medios de filtro.
