Water Filtration in Guatemala

As a new member, it is interesting to me to see the fact that you are using the same filters as those used by Pure Water for the World. This fact indicates a good relationship. As a Rotarian, I am interested in the extent that you are cooperating with the Rotary Clubs in Guatemala. As you may know, The Rotary Club of Guatemala Sur is deeply involved with water filtration using another type of in-home filter. It occurs to me that some applications are better served using one type and other applications are better served with the other. See bombagua.com.gt.

Any experiences?
