I have been travelling through Africa on business a lot and have seen what happens in terms of water supply. It is sometimes scary to see what this people have to drink to stay alive. Especially to those of us conscious about filtering water. This is a great job that was done. Although still pricy, considering that some people especially in Africa have to live on less than $ 1-00 per day. Let us just hope that those with more blessing will keep on helping to get these products out there. Great Job Done.
