<p>An automotive air filter including natural fiber filter media region, having pileous, absorbent, wickable natural fibers, a synthetic fiber filter media region including, absorbent spunbond polyester filters. The natural fiber region receives an influent fluid stream containing particles, trapping some particles. The manufactured fiber region removes residual particles, producing a filtered effluent stream. The fluid stream passes unimpaired through the fiber pores. Two structural mesh layers sandwich natural and manufactured fiber regions. Oil is disposed in the oleophilic cotton mesh. Fiber regions have layers disposed in gradient density arrangement.</p> |
