Abstract

Selon l'invention, un ensemble de filtration d'air comprend un orifice d'entrée, un orifice de sortie, et un sous-ensemble de déplacement d'air servant à aspirer de l'air extérieur et à déplacer cet air au travers de sous-ensembles de traitement d'air modulaires à l'intérieur de l'ensemble de filtration d'air. Le sous-ensemble de déplacement d'air pousse alors l'air traité hors de l'orifice de sortie. Chaque sous-ensemble de traitement d'air modulaire peut accueillir un type de système de traitement d'air différent qui traite la poussière, les polluants automobiles et industriels, des éléments chimiques et métalliques dangereux, des allergènes, et des odeurs, etc. Ledit ensemble de filtration d'air peut être mis en fonctionnement par des sources d'énergie intégrées ou extérieures, de façon à pouvoir se raccorder à un masque facial pour fournir une filtration d'air personnalisée, ou utilisé avec un ensemble d'évent de fenêtre, à insérer dans une ouverture de fenêtre, pour traiter l'air de l'extérieur avant de l'envoyer dans une pièce.
