摘要： A water filter assembly and water filter element [1] are provided. The water filter element has water permeable barriers through which water is to be passed in use in order to purify same. The permeable barrier comprises a nanofibre layer [9] defining nanopores through which water is to permeate in use. The water filter element may be in the form of an enclosure [2] housing at least one of granular activated carbon, at least one appropriate ion exchange resin and at least one appropriate adsorbent [7]. Preferably, the water permeable barrier comprises a permeable support layer [8] and a nanofibre layer [9] carried thereby. The nanofibers preferably have antimicrobial properties that are either inherently a property of the nanofibres themselves or provided by a biocidal agent entrained or otherwise trapped within the nanofibres or a layer thereof, or both. The water filter assembly has a perforated holder [3, 23] that operatively snugly receives the water filter element in a flow path through the water filter assembly. Preferably, the perforated holder has a screw threaded socket [5, 26] for attaching it inside the mouth of a container [4].
