Abstract
Cette invention concerne des filtres de diverses natures destinés à être utilisés dans des systèmes de conditionnement d'air et d'épuration de l'air, en particulier des filtres traités avec des matériaux photocatalytiques et des matériaux nanométriques visant à éliminer la contamination par des espèces bactériennes et virales, même en l'absence de rayonnement lumineux. Cette invention concerne en particulier des filtres photocatalytiques (2) qui comprennent, sur la surface de ces filtres (2), une ou plusieurs couches superficielles de composés présentant une activité photocatalytique comprenant du dioxyde de titane photocatalytique.
