Filtralite Pure HC 0,8-1,6 is a high-quality filter media, manufactured from expanded clay material, used for filtration in drinking water treatment and in swimming pool filters. Combined with Filtralite Pure NC 1,5-2,5, they offer the Filtralite Pure Mono-Multi solution.
Filtralite filter media, with its highly porous structure, enables improved filter efficiency by longer filter runs between backwashes, which means reduced energy and water consumption and higher water production, consequently giving reduced operating costs.
