The purpose of the present invention is to provide a liquid permeable body comprising a porous composite that has different liquid permeabilities between in the in-plane direction and in the out-of-plane direction as well as excellent mechanical properties. The liquid permeable body comprises a porous composite having a structure in which discontinuous reinforcing fibers are dispersed; the dispersed discontinuous reinforcing fibers are bonded with a thermoplastic resin at at least an intersection thereof; voids of continuous openings form a void content of from 30 to 90%; an average value of fiber orientation angles is from 0 to 40 in an in-plane direction of the discontinuous reinforcing fibers; and an average value of fiber orientation angles is from 0 to 25 in an out-of-plane direction of the discontinuous reinforcing fibers.

The present application relates to a multifunctional filter medium and a method of manufacturing the same. The multifunctional filter medium of the present application is capable of significantly reducing fine dust, harmful microorganisms, and toxic gases and reducing a pressure decrease during filtration due to exclusion of high-density nanofiber, thereby minimizing energy required for filtration and exhibiting sufficient filtration performance as a single filter medium.

A filter housing can be configured to receive a filter media to form a filter assembly. Water filter media assemblies can be adapted for filter-as-you-pour filtration in the context of container (e.g., pitcher) systems where filtering is achieved as the user pours water from the container. The filter housing can have a frame and an optional casing securable about the frame. The filter assembly can include a filter media within, connected to, or associated with a filter housing. The filter media can be securable in an at least partially curved configuration and/or within, connected to, or associated with the filter housing.

A waterless vacuum based smoking apparatus utilizes vacuum created by translation of a cartridge within a chamber of a sheath body in order to accumulate within the chamber smoke or vapor from a combustible or vaporizable substance, which can then be expelled for inhalation by a user by reversing the translation of the cartridge within the chamber. Measurement and tracking functionalities are provided so that a user may accurately assess and monitor their intake.

The invention provides an antimicrobial fiber which exhibits excellent antimicrobial properties even without the addition of antimicrobial agents and can remain antimicrobial even after repeated washing. The antimicrobial fiber comprises a fiber having on a surface thereof a polyacetal copolymer (X) containing oxyalkylene groups, the molar amount of oxyalkylene groups in the polyacetal copolymer (X) being 0.2 to 5 mol % relative to the total of the molar amount of oxymethylene groups and the molar amount of oxyalkylene groups.

The present invention provides a system and methods for filtering fluid using filter papers, stationary paper, cloth sheets or any other porous material. In one embodiment, the present invention uses the lateral flow direction along the porous sheets, instead of conventional vertical flow direction, for the removal of bacteria and particle contamination in the range from nanometers to millimeters. The pore sizes in the filter media along the lateral direction are modulated by controlling the compression of the porous sheets, instead of conventionally designing filters with different pore sizes. The lateral flow fluid filter system is scalable simply by increasing the feed area, feed length, and the number of porous sheets. The invention presents a universal fluid filtration system for wide range of applications such as water purification, food processing, chemical industry, oil and gas industry, and biological applications.
