This paper shows main physical - mechanical characteristics of tuff as a material useful for making filters. Important feature of the tuff is that, chemically, is very stable material, it is composed of SiO2 which not react with water, it doesn’t lose its weight and not releases harmful and hazardous organic and inorganic substances. Briefly are described fundamental physical phenomena briefly explained the fundamental physical phenomena that define the filtration as mechanical retention of particles, sedimentation, adsorption and absorption.Presented is mathematical model for making filter from this material, and application in the two-layer filters in combination with quartz sand as a bottom layer and active carbon as a surface layer. In this type of filters, active coal has the function of removing chemical and biologic contaminants. In the model is defined needed height of the filters fillers, hydraulic resistance in the filter layers, drop of pressure through the filter layers, or defined are all needed parameters for making real filter. This model is tested in laboratory and real conditions.
