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 wherein at least a portion of the plurality of filter particles is at least partially coated with silver or a silver-containing material. 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.

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 having a permeability of greater than about 3.0*10−9 cm2, and a F-VLR of greater than about 99% is provided. The filter block may be made of filter particles having a median particle size of less than about 50 microns and having a particle span of about 1.4 or less. The filter blocks of the present invention can be used to make a filter for filtering liquids and more specifically, for providing potable water. The filter particles may be mesoporous. Kits comprising filters and information relating to the killing or removal of bacteria, viruses, and microbials are also provided.
