José Fernando Mazariegos Anleu (21 March 1938 – 2 June 2018[1]) was a Guatemalan inventor, recognized in several countries in Latin America, Asia and Africa, for the creation of the drinking water filter called "Ecofilter", which was developed in 1990 as part of a project of the Central American Institute of Industrial Research and Technology.
His professional development was carried out at the Central American Institute for Research and Industrial Technology, an institution that allowed him to share his knowledge in favor of environmental development in the urban centers of the Central American region, where he conducted a series of seminars and projects for municipalities.
The objective of the Ecofilter was to obtain potable water at low cost, taking advantage of raw materials and local technology.
[5][6] The filter was developed in order to put it at the service of the population, and is already used in countries in Africa, Asia, the Caribbean and South America.
One of the most responsible for the extension of the use of these filters was Ron Rivera with his organization Potters For Peace.
