Images-29 Awhile back we covered the LifeStraw – a 25 cm long, 29 mm diameter, plastic pipe filter purchased costs around US 2.00 that could possibly be a great and low cost way to get clean water. With a lot of people out of drinkable water in the south, I though it might be good to post up a list of ways to make drinking water- not a bad thing to know how to do…If you have resources, link, etc.. post them up.
