Filter-Ag Plus is a natural mineral possessing a number of unique advantages compared to common sand and mixed filter media used for suspended solids reduction.

Key advantages:

  • increased depth of the filtering bed to enhance quality of the purified water

  • high sediments reduction capacity results in longer filter runs and significantly lower water consumption

  • high efficiency of the media leads to lower capital costs and saving of space needed for equipment placement

  • replacement of mixed media with Filter-Ag Plus increases filter capacity by 100%

  • Filter-Ag Plus is a natural and environmentally safe media

Filter-Ag Plus is a natural mineral clinoptilolite that possesses impressive advantages compared to those intrinsic to traditional sand and mixed filter media used for suspended solids reduction.

Through a scanning electron microscope its granules look like polyhedrons with textured surface and microscopic pores with size larger than 3 microns. These features make their surface over 100 times bigger than that of quartz sand.

Angularity of the granules and tapering pores contribute to retention of dirt, silt and organic matter suspended in the water by means of flocculation, steric effect and adhesion. The textured surface and porosity provide larger surface to effectively retain the suspended impurities.
