Most of us have water all around us but it is undrinkable, good survivalists should be able to make use of that water but for city dwellers, someone who is sick or injured or someone that is too busy and desperate to have to deal with the elaborate processes of sterilizing drinking water, or even good survivalists that have to move from their home for some reason, everyone should have a water filter like this one.
It costs over $200.00 dollars but it can be passed down to your children, in a hurricane you can eliminate drinking water from your many concerns by putting one of these in your pocket, in the city you can utilize water that you would normally never touch, if you have old stored water that you no longer trust then put it through something like this.
Everyone should find water filters that fit their needs, including one for being mobile, there are many competing models and manufacturers.

One thing alot of folks forget though is that you can sterilize water by boiling it.
I would have no problem drinking lake water if it was boiled and filtered. If it didn’t kill the fish, you’re probably good. I would be cautious about doing it for more than a couple weeks, though, because of possible contaminants.
