    摘要： Disclosed is a method of providing potable water that includes providing a filter, passing water through the filter, and removing bacteria and viruses from the water with the filter. The filter comprises a housing having an inlet and an outlet and a filter material disposed within the housing, the filter material formed at least in part from a plurality of filter particles consisting of mesoporous activated carbon. A sum of mesopore and macropore volumes of the filter particles may be between about 0.2 mL/g and about 2 mL/g, wherein mesopore means an intra-particle pore having a diameter between 2 nm and 50 nm, and macropore means an intra-particle pore having a diameter greater than 50 nm, a total pore volume of the filter particles is greater than about 0.4 mL/g and less than about 3 mL/g, and a ratio of the sum of the mesopore and macropore volumes to the total pore volume of the filter particles is greater than about 0.3. The filter removes bacteria and viruses from the water at a level of Filter Bacteria Log Removal of greater than about 2 logs and a Filter Viruses Log Removal of greater than about 1 log.

    摘要： A filter block may comprise activated carbon filter particles without metallic biocides. The activated carbon filter particles may have a median particle size of less than or equal to about 90 microns and having a particle span of less than or equal to about 1.7. The filter block may have a permeability of greater than about 3.0×10−9 cm2 and a Filter Viruses Log Removal of greater than about 2 logs. A portion of the activated carbon filter particles may be coated with a cationic polymer. Another filter block may comprise mesoporous activated carbon filter particles without metallic biocides, wherein the mesoporous activated carbon filter particles may have a median particle size of less than or equal to about 104 μm and a particle span of less than or equal to about 2.05, and wherein at least a portion of the filter particles may be coated with a cationic polymer. The filter block may have a permeability of greater than about 2.0×10−9 cm2 and a Filter Viruses Log Removal of greater than about 2 logs.
