Crystal clear water: Filters without flocculation with a sharpness of 1 micron. Healthy air: Reduces harmful chlorine by-products and chlorine odour by 50 %. Better water quality: Provides protection against chlorine-resistant pathogens. Lower costs: Reduces backwash water and chlorine consumption. Sustainable filtration: Has a longer service life than any other filter material. The 100 % bioresistant filter material prevents bacterial growth in the filter bed and reduces harmful disinfection by-products. AFM produces crystal clear and safe water with healthy air and no chlorine odour. The consumption of water and energy is reduced and the service life of the filter material is longer than that of conventional filter materials. AFM can be used in all sand filters. Grain size: 0.4-1.2 mm.
