Product review (5 stars): Support this company!
Works as advertised and delivered faster than expected. The real reason I am leaving this feedback is that when I was considering several options for filter this wasn't the cheapest. But the fact that they work in developing countries to help with water access issues pushed me to buy from them. I will always buy from vendors that donate time and resources to worthy causes even though it may cost me slightly more. We should all support this company and others like it.
