description	The present invention relates to filtration media made from melt-blown fibers having improved barrier properties. The melt-blown fibers in the filtration media of the invention are made of a visbroken metallocene-catalyzed propylene homopolymer composition with specified melting temperature Tm and molecular weight distribution (MWD). La présente invention concerne des milieux de filtration fabriqués à partir de fibres soufflées à l'état fondu ayant des propriétés barrières améliorées. Les fibres soufflées à l'état fondu dans les milieux de filtration de l'invention sont constituées d'une composition d'homopolymère de propylène catalysée par un métallocène viscoréduit ayant une température de fusion Tm et une distribution de poids moléculaire (MWD) spécifiées.
