Abstract
The current technology relates to filter media configurations where the filter media has a surface with a treatment that increases the roll off angle of the surface for a 50 μL water droplet when the surface is immersed in toluene. Some example filter media have a fluted configuration, and some example filter media have multiple layers. Filter media having multiple layers can be single facer media, for example, where one layer is planar and another layer is fluted.
