Ekofil filters are composed of a ceramic filtering unit (made of clay, saw dust and colloidal silver) that hangs inside a container equipped with a top and a spigot for the filtered water. The network of microtubes produced after the burning of the say dust provides the means to retain microorganisms and parasites higher than 0.1 microns.
The filtering unit has a water filtering capacity volume of 9 liters. The container which holds the filtering unit can be made of red clay or plastic of different colors (white, blue, green). Clay containers can hold 20 liters while plastic containers can stores 25 liters of filtered water. The filtering unit has a filtering rate of 1,5 – 3,0 L/hour. For optimal performance, the Ekofil filtering unit should be kept full at all times.

No known risks are related to the use of this product. No dangerous chemicals are used in its manufacturing.Interview with representative
No complementary technical systems are required.
It is however possible to purchase additional options such as an automatic system for the control of filling, a metal structure to support the filter, or filters in series for high consumption facilities (schools, care centers, etc).
