Filette, one of the purest low-mineral waters in the world, gushes out clear from the spring of Guarcino at 900 meters above sea level, in the green and uncontaminated setting of the mountains of the Lazio Apennines. The absence of arsenic, the almost total absence of nitrates, the low sodium content and the perfectly balanced fixed residue make Filette a precious water for health and particularly suitable for daily use.
