Abstract:
A filter media is generally described including an upstream layer of a nonwoven fiber having a denier between about 5.0 and 7.0 and a weight of between about 3.0 and 5.0 opsy, optionally a scrim, and a cap layer of a fiber having a denier between about 0.1 and 5.0, and a weight between about 2.0 and 4.0 opsy carried by the upstream layer and disposed downstream from the upstream layer. The upstream layer, scrim and cap layer can have a weight of about 4.0 opsy, 2.0 opsy and 3.0 opsy respectively. A downstream layer can be disposed between the upstream layer and the cap layer.
