How the #nofilter hashtag helped
people with no water filters.


#nofilter is one of the biggest hashtags on Instagram. And 1 billion people in the world don’t have access to clean water because they have no filters.


To bring attention to the global water crisis and help those in need, we filtered all #nofilter posts on instagram and converted them into clean water.

Original post

One billion people in the world have NO water FILTERS, thus no access to clean water. But we can change that starting today on #worldwaterday. Repost this, or create your own #nofilter post. For every #nofilter post on Instagram (past and present), one gallon of clean water will be made accessible by @wavesforwater teams around the world.
