Insight 
Contaminated water is the source of 80% of all illnesses in developing countries. And all it needs to prevent this is a filter. However: the problem is out of sight and out of mind. Thankfully, millions of people already use filters every day – photographic filters on apps like Instagram. 
Idea
"A Filter for a Filter" the worlds first digital photo filter, that filters water filters in developing countries. Execution: In a cooperation with Instagram, we launch one additional filter for the app carousel. With a cost of 2 euros, the revenues are used to finance real, life saving water filters. The filter provides a unique "filtered through water" look and can easily be shared like a badge of pride on social media channels.
