Point of use or point of dispense filter with multiple pleat packs

A filter, comprising:

• a body having a cavity and a non-cylindrical shape defined by side walls;
• a plurality of pleat covers defining a first side channel, a first region, a center channel, a second region, and a second side channel in the cavity, each pleat cover of the plurality of pleat covers having openings, wherein the first side channel is disposed between the first region and a first sidewall, the second side channel is disposed between the second region and a second sidewall, and the center channel is disposed between the first region and the second region;
• a plurality of pleat packs comprising a first pleat pack positioned in the first region and a second pleat pack positioned in the second region, wherein each pleat pack of the plurality of pleat packs comprises a rectangular pleat pack having a generally planar rectangular entrance interface and a generally planar rectangular exit interface;
• a first end cap bonded to the body at a first end of the body, the first end cap having a first opening and a first flow passage, the first opening connected to an inlet port, the first flow passage structured for directing a fluid from the inlet port to the center channel, wherein the fluid is directed from the center channel through the first pleat pack positioned in the first region, through the second pleat pack positioned in the second region, and through the openings via parallel flows to the first side channel and the second side channel, respectively;
• and
• a second end cap bonded to the body at a second end of the body, the second end cap having a second opening and a second flow passage, the second opening connected to an outlet port, the second passage structured for directing the fluid from the first side channel and the second side channel to the outlet port,
• wherein the fluid is a semiconductor liquid, and the plurality of pleat packs is configured to remove contaminants from the semiconductor liquid by comprising pleated membranes having a particle size retention rating of 20 nanometers or less,
• wherein the plurality of pleat covers comprises a cage defining the center channel that separates the first region and the second region,
• wherein the cage comprises a structural support member positioned between the plurality of pleat covers, the structural support member being separated from the plurality of pleat covers by first and second walls of the cage,
• wherein the pleat covers of the cage have openings and wherein the first and second walls of the cage are solid.
