__NOTOC__===Extremely affordable water filters===
A question: if we can fly to the moon, can we make a 1$ water filter for people to use in their homes? And, if the answer is yes, why haven’t we yet? This is one of my favourite things: the quest for extremely affordable point-of-use water filters.

====Why it is smart====
At the moment, the filter is being implemented by [http://www.enterpriseworks.org/ EnterpriseWorks/VITA], and [http://www.connectinternational.nl/english/smartmodules/smart-tec/water-treatment/siphonwaterfilter Connect International] in Cambodia, Tanzania, Mozambique, Madagascar, Kenya, India, and other countries. Good luck people!
