Abstract

L'invention concerne un filtre anti-contamination moléculaire en suspension dans l'air. Le filtre anti-contamination moléculaire en suspension dans l'air comprend un premier milieu filtrant qui élimine des premiers contaminants en suspension dans l'air d'un premier flux d'air, et un second milieu filtrant en aval du premier qui élimine des seconds contaminants en suspension dans l'air d'un second flux d'air sortant du premier milieu filtrant. Au moins l'un du premier et du second milieu filtrant comprend un milieu filtrant non carboné sensiblement fonctionnalisé qui élimine un acide faible d'au moins l'un du premier flux d'air et du second flux d'air.
