Abstract:
A fluid filter media, comprising:a. a natural fiber filter media region receiving an influent fluid stream containing particles, the natural fiber filter media having pores therethrough and being formed from a pileous, absorbent, and wickable natural fiber, the natural fiber filter media region trapping therein a first portion of the particles in the influent fluid stream while the influent fluid stream passes substantially unimpaired through the pores, and creating a filtered fluid stream having therein a second portion of the particles thereby; and b. a manufactured fiber filter media region in proximate contact with, and in fluid communication with, the natural fiber filter media region and receiving the filtered fluid stream therefrom, the manufactured fiber filter media region having pores therethrough and being formed from a pre-selected pileous and absorbent manufactured fiber, the manufactured fiber filter media region trapping therein a substantial amount of the particles of the second portion in the filtered fluid stream while the filtered fluid stream passes substantially unimpaired through the pores, and releasing a filtered effluent fluid stream thereby.
