Abstract
A filter for producing potable water filter comprises a housing including a water inlet and a water outlet, and a filter material arranged within the housing. The filter material comprises activated carbon particles, and a plurality of carbon nanofilaments disposed on the surface of the activated carbon particles. The filter is operable to provide potable water by removing contaminants from a liquid water stream flowing from the water inlet to the water outlet of the housing.
