The invention is a fluid system with an internal filter assembly that prevents particulate from moving between portions of the fluid system. The internal filter assembly is located within a fluid path extending between a particle source, such as a textile tensile member, and a portion of the fluid system that may be affected by particulates from the particle source, such as a value. The fluid system, and particularly the internal filter assembly, has applicability to articles of footwear, for example.
