TED Talks – Make filthy water drinkable by Michael Pritchard

Updated: Jan 23, 2019

Too much of the world lacks access to clean drinking water. Engineer Michael Pritchard did something about it — inventing the portable Lifesaver filter, which can make the most revolting water drinkable in seconds. It can filter up to 6000 liters of water completely free of all viruses, bacteria, and heavy metals.

This makes it very well suited for saving lives in poor countries and providing clean water for disaster stricken areas. Plus it is a nice portable way to get some fresh clean water when camping, hiking, or for outdoor sports like long distance running and biking.

“For $20 billion everyone can have access to safe drinking water. So the 3.5 billion people that suffer every year… and the 2 million kids that die every year will live.” -Michael Pritchard

    There are many filtration methods in the market but I would prefer the reverse osmosis is the better choice, it has pore hole size up to 0.0001 microns, is the most economical method of removing 90% to 99% of all the contaminants, which produces the cleanest water for drinking.
