Acqua Filette, with only 0.2 mg/l of Nitrates and a complete absence of Arsenic, is one of the purest mineral waters in the world.
 Thanks to the uncontaminated terroir where the source is located, in Guarcino at an altitude of 900 meters above sea level, through basalt rocks and volcanic sediments on the slopes of the mountains of the Appennino Ernico, this water is extremely pure. The spring is surrounded by a beautiful and uncontaminated wooded area where the air is full of ozone.
 Being bottled and distributed from 1894, in the 20th century Acqua Filette became famous as therapeutic, healthy and curative water, with particular diuretic, digestive and anti-uric action. Acqua Filette Srl, is certified according to UNI EN ISO 9001: 2015, an international guarantee of reliability in the bottling and distribution process.
