Abstract

La présente invention décrit un filtre à air capable d'éliminer des composés organiques volatils, contenant principalement une charge de structure en réseau rétiforme métallique supportant un TiO2 de type anatase et au moins une lampe UV. Il y a un creux à l'intérieur de la charge, la lampe UV étant dans celui-ci. Dans ce filtre, les composés organiques volatils (COV) sont décomposés rapidement et de manière efficace par l'effet de catalyse du nano-TiO2 sous un rayonnement UV, une efficacité de filtration étant ainsi obtenue. Tandis que l'on élimine diverses substances nocives à l’aide d’un TiO2 de type anatase, l'air purifié sera évacué au niveau de la sortie du filtre, et l’on peut de ce fait éliminer les composés organiques volatils mortels pour les humains de manière plus efficace.
