Abstract

L'objectif de cette invention est d'obtenir un filtre photocatalytique qui ne se brise pas et dans lequel de la poussière du matériau constituant ce filtre n'est pas produite lorsque le filtre photocatalytique subit un choc. Un matériau coussin (32) est fixé à la périphérie des faces latérales (6S) du filtre photocatalytique (6) en forme de plaque, mais pas sur la face avant (6A), ni sur la face arrière (6B). Un élément cadre (31) fait en sorte que la face avant (6A) et la face arrière (6B) soient exposées, et simultanément, que le filtre photocatalytique (6) soit logé à l'intérieur de cet élément cadre, de manière que ce dernier soit en contact avec le matériau coussin (32) fixé sur le filtre photocatalytique (6).
