A better access to drinking water?

A woman using a LifeStraw

My dear readers,

For my last post I spoke about food. I want to talk about something which is related to food, it's water and drinking water. 
At the moment, around 884 million people in the world, 37% of whom live in Sub-Saharan Africa, drink water from unreliable sources of drinking water. This increases the risk of having diseases such as cholera or typhoid. Each year approximately 3.4 million of people die because of this lack of safe water. 
Recently, a company invented a straw to filter water and drink it safely. This  object, called LifeStraw, has more or less the same shape as a straw. It removes all bacteria and parasites in filtering the water. No bacteria and parasites means that it is a efficient way to avoid diseases and death. 
This LifeStraw requires any electrical and battery power and because of its small size it may be carry everywhere. So to recap this objet is like a little revolution for countries lake drinking water. 
But (there is always a but!) it is produced by a company so I am quite sceptical about the accessibility of this (great) invention for population at a disadvantage. I am afraid that one more time money will take precedence over people. 
This invention is absolutely new so we have to wait a little bit and hope that my skepticism wasn't fair.
