Novel fibrous structures that contain filaments, and optionally, solid additives, such as fibers, for example wood pulp fibers, sanitary tissue products comprising such fibrous structures, and methods for making such fibrous structures and/or sanitary tissue products are provided.

Novel fibrous structures that contain filaments, and optionally, solid additives, such as fibers, for example wood pulp fibers, sanitary tissue products comprising such fibrous structures, and methods for making such fibrous structures and/or sanitary tissue products are provided.

Multi-phase filter media, as well as related articles, components, filter elements, and methods, are disclosed.

Filter media are described. The filter media may include multiple layers. In some embodiments, the filter media include a nanofiber layer adhered to another layer. In some embodiments, the layer to which the nanofiber layer is adhered is formed of multiple fiber types (e.g., fibers that give rise to structures having different air permeabilities and/or pressure drops). In some embodiments, the nanofiber layer is adhered to a single-phase or a multi-phase layer. In some embodiments, the nanofiber layer is manufactured from a meltblown process. The filter media may be designed to have advantageous properties including, in some cases, a high dust particle capture efficiency and/or a high dust holding capacity.
