A liquid filter cartridge is provided. Preferred seal arrangements are provided, to provide for preferred axial load conditions, with respect to one or more of the end caps of the cartridge. Some cartridge configurations provided include no core structure or outer liner structure therein, to support axial load. Assemblies using the cartridge, and methods of assembly and use, are provided. The liquid filter cartridge can be a serviceable cartridge, or it can be retained permanently in a housing.

The disclosure provides a filtering device comprising a housing, a blocking member and a screening member. The housing includes a body, an inlet end and an outlet end. The housing forms an accommodation space. The inlet end and the outlet end are respectively formed at two ends of the accommodating space. The inlet end is capable of receiving fluid. The blocking member is capable of splitting the fluid into a plurality of fluids and collecting the non-fluid composition of the secondary fluid having a first size. The screening member is disposed between the inlet end and the blocking member, and the screening member is configured to receive the secondary fluid to limit the non-fluid composition having a second size of the secondary fluid to the screening member. After the secondary fluid passes through the shield and the screening member, the secondary fluid is output from the outlet end.

The present disclosure provides small diameter tubular porous fiber filters. These tubular porous fiber filters have many uses including but not limited a filtration medium for removing particles of 5 microns or less from liquid or air.

A filter element for the filtration of fluids can be manufactured from powdered metal using a laser manufacturing process. The powdered metal is deposited in a layer on fabrication platform and a laser beam is directed toward the layer of material so that the powdered metal granules fuse together to form a first component of the filter element. Successive layers of powdered metal can be deposited over the first component and also fused with the laser beam to form additional components. During the manufacturing process, the power or scan rate of the laser beam many be changed so that the formed layers of the filter element may have different porosity characteristics, for example, with certain portions being fluid permeable and other portions being fluid impermeable.
