life straw is better than nothing problem is the 1000 l is only in non sediment water and there is no way to clean it. carrying berkey filters is a better long term solution but more costly about $100 for two black filters which you can clean…. i have drank dirty water that has been filtered by them with no ill effects. they also have a sports bottle sized filter which i moved to work in a ss water container instead of plastic sports container. you can take filter out ans “wash ” it.
