Silver Filter
The Silver Filter Company Ltd.
The Silver Filter is a type of ceramic water purifier enhanced with colloidal silver.
Silver Filters are silver enhanced ceramic ‘pot’ water filters for household drinking water treatment. This filter was first developed in 1981 by Dr. Fernando Mazariegos of the Central American Industrial Research Institute (ICAITI) in Guatemala and is now promoted by Potters for Peace (PFP), a USA based nonprofit organization. These filters are low-tech and low-cost water filters that eliminate approximately 99.88% of water-born disease agents at the flow rate of 1-3 L/h.
This product is mainly implemented by Potters for Peace but is distributed worldwide by organizations such as the International Federation of the Red Cross and Red Crescent, Doctors Without Borders, UNICEF, Plan International, Project Concern International, Oxfam and USAID.
Primary competitors of these silver-enhanced ceramic filters include Ekofil filter, Ceramic filter UTP, Arcifiltro, Ecofiltro, or ceramic candle filters such as Stefani filtro flex.
