Each Lifestraw purchased is a Lifestraw that is distributed to schools in Africa!!
Not only are you getting a great product, but you are literally saving lives across the world.
I have purchased two of these for myself but I haven't tested or used them yet. They have a three year shelf life so I will use them by then, but until then I keep them for emergencies. Here is a video from Lifestraw.com about the product.
