Abstract

L'invention concerne un système de purification d'air individuel portatif, comprenant une unité filtre à air destinée à un dispositif de purification d'air individuel portatif servant à purifier l'air ambiant et à fournir de l'air purifié, ladite unité filtre à air comprenant un boîtier de filtre définissant une chambre de logement dans laquelle est logé au moins un élément filtrant, ladite chambre de logement étant délimitée par un fond de boîtier et une paroi de boîtier de filtre périphérique extérieure, s'étendant à partir du fond de boîtier. L'objectif de l'invention est d'améliorer ce système de purification d'air portatif de sorte qu'il soit le plus simple possible à manipuler. Cet objectif est atteint par le fait que la chambre de logement est fermée au moyen d'un couvercle de boîtier situé à l'opposé du fond de boîtier, à l'exception d'au moins une ouverture d'entrée d'air.
