Beschreibung
Zusammenfassung:	A composite media includes a stack with 20 or more layers, each layer including a substrate with a first major surface and an opposing second major surface; and a fiber layer deposited onto the first major surface of the substrate and including polymeric fibers with a diameter of 100 nm to 1.5 μm. Each fiber layer independently has a thickness of 5 μm to 100 μm, and each layer independently has a pore size of 0.1 μm to 10 μm. A filter may include a housing and the composite media disposed within the housing. The filter may be a syringe filter.
