Abstract:
PROBLEM TO BE SOLVED: To provide a fluid filter containing a composite filter medium for a water filtering carafe, which removes dissolved chemical contaminants and particulates of a size in the 3 to 4 micron range from a fluid. SOLUTION: The fluid filter includes an outlet end panel 102 with an opening 104 and a sheet-like composite filter medium 10 capable of sealably covering the opening 104. The sheet-like composite filter medium 10 is pleated so as to have a first outward pleat 106a, an inward pleat 106b, and a second outward pleat 106c, and the pleats define four filter medium panels including a first filter panel 108a, a second filter panel 108b, a third filter panel 108c and a fourth filter panel 108d. The composite filter medium 10 includes an adsorbent layer for removing the dissolved contaminants and a hydrophilic particulate intercepting layer for removing particulates.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for improving the performance of existing filtering media. SOLUTION: Many fibrillated nanofibres are prepared. The fibrillated nanofibres are wet-laid or applied via coating on an existing filtering medium from a fluidized suspension. At this time, the fibrillated nanofibres are loaded onto the existing filtering medium at a rate of approximately 0.5/m 2 to approximately 11.0 g/m 2 , thereby increasing the performance index of the existing filtering medium by at least approximately 100%.

Abstract:
PROBLEM TO BE SOLVED: To provide a nanofiber filter medium for removing impurities from a fluid such as a liquid. SOLUTION: An air filter medium includes: a nanofiber; and a filter medium having a thickness of less than about 0.25 millimeters, a performance index of greater than about 0.075, and further filtration efficiency of greater than about 99.9% when capturing aerosol particles of about 0.18 microns in size and a pressure drop of less than about 40 millimeters water column in the case in which a sample the size of which is 100 cm 2 is passed through at a flow rate of about 32 liters/minute and captured. A coating of the nanofibers may also be used to enhance performance of existing filter media by increasing the FOM of the existing filter media. Preferably, the nanofibers are fibrillated.

Abstract:
PROBLEM TO BE SOLVED: To provide a filter medium having a microbiological interception function, filtration systems including the filter medium, and a method of manufacturing the same. SOLUTION: The invention is directed to a microbiological interception enhanced filter medium comprising a microporous structure having a mean flow path of less than about 2 microns and made of an array of active particles. At least a portion of the surface of microporous structure has formed thereon a microbiological interception enhancing agent comprising a cationic material in combination with a biologically active metal. The microbiological interception enhanced filter medium is provided with a viral interception of greater than about 4 log, and a bacterial interception of greater than 6 log.
