Abstract: A particle filtration system that includes first, second and third filter segments that each include several first, second and third filters. Each first, second and third filter includes a fibrous layer sandwiched between a pair of surface or outer layers. The range of pore sizes of each first, second and third filter varies according to the density of the surface layers relative to the fibrous layers.

Abstract: A filter assembly includes an inlet end, a sediment filter having a sediment filter surface facing the inlet end and cylindrical filters. The sediment filter surface is orthogonal to each cylindrical filter surface. A first channel and a second channel may fluidly connect the sediment filter to the more cylindrical filters. The first channel can have a central axis that is orthogonal to a central axis to the more than one cylindrical filter. A central axis of the second channel may be in a direction along the length of the more than one cylindrical filter.
