Abstract
A filter for the purification of tap water containing several layers of different filter materials. One of the layers is an adsorption filter element comprising a self-supporting sintered body of finely dispersed adsortion material, e.g., activated charcoal, a thermoplastic binder material and a finely dispersed, oligodynamic material, wherein these materials provide a fine-mesh, mechanical filter. The adsorption filter can also be used by itself for filtering purposes.
