Ecofiltro is a product that was invented by Fernando Mazariegos in 1981. It is an artisanal water filter made of clay, sawdust, and colloidal silver where clay builds small channels in the inner walls of the water filter, the sawdust, turned into activated charcoal removes any smell or taste in water, and the colloidal silver works as a disinfectant for the water, on the surface of the clay filtering unit.
