Multiport filter housing and filter thereof

A method of filtering liquid with a filter that includes a filter member and a filter housing, the filter housing including a sleeve, a first endcap coupled to a first open end of the sleeve and including a first plurality of ports, and a second endcap coupled to a second open end of the sleeve and including a second plurality of ports, at least one of the first endcap and the second endcap being removably coupled to the sleeve, the filter member disposed in the sleeve between the first endcap and the second endcap, the method comprising:

• supplying a liquid into the filter housing through at least a first port in the first plurality of ports in the first endcap;
• directing a first portion of the liquid from the first port in the first endcap to a first port in the second plurality of ports, which includes passing the first portion of the liquid through the filter member;
• and
• discharging the first portion of the liquid from the filter through the first port in the second endcap, the first portion of the liquid being a permeate.

A filter, comprising:

• a filter member;
• and
• a filter housing enclosing the filter member, the filter housing including:
• a sleeve including a first open end, a second open end, and an interior volume, the filter member disposed in the interior volume of the sleeve, the interior volume having an outer radial portion and an inner radial portion;
• a first endcap coupled to the first open end of the sleeve, the first endcap including a first plurality of ports that connect to the outer radial portion and the inner radial portion of the interior volume of the sleeve;
• and
• a second endcap coupled to the second open end of the sleeve, the second endcap including a second plurality of ports that connect to the outer radial portion and the inner radial portion of the interior volume of the sleeve,
• wherein at least one of the first endcap and the second endcap is removably coupled to the sleeve, and the filter member is enclosed in the sleeve between the first endcap and the second endcap.
