ABSTRACT:
A filter block having a permeability of greater than about 3.0*10−9cm2, 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.
