Scientists create a cheap paper water filter that removes lead, arsenic and bacteria while being portable and disposable.

Dong currently sells a six-pack of Mesopaper on Amazon for $6.99. Each nine-inch diameter sheet can filter about 22 liters, or about six gallons, of water before needing to be replaced, which translates to about 36 gallons of clean water for just $7. This comes out to just under 20 cents per gallon of clean water, which is about as cheap as it gets apart from maybe a whole-house water filtration system.
