Preparing to survive if the world turns to crap.

You know, there may come a time when you have to drink water. Generally, that time is every day. At most, you have three days without water before you die, but that's just being generous about it. If there comes a time when you aren't as privileged as you are now, you may have to find and disinfect your own water. Now, it would be nice if you had a really expensive water filter to take around with you. Not all of us are made of money and sometimes prepping is about sacrificing one really good thing so you are prepared overall, which is a much better way to do it. Unless you are moneybags and you can afford a fully stocked survival retreat in the middle of the woods with everything you'll ever need. If that's the case, and you are female, you may marry me if you wish.
For the rest of us though, making water safe to drink is going to be an ongoing issue. Even if we do have one of those expensive water filters, eventually it'll break and we'll be looking for other ways.
First off, we should learn some basic water treatment, of which I conveniently did a post, linked below:
Everybody read that? Good! Now we can move on. From the above article, we know that to get the greatest chance of water that won't kill you or make you sick, you need to do two things:
Now, to filter it, you can use a multitude of things. I've used a stack of coffee filters. Seriously, they work well in filtering muddy water, as such:
1 - Get yourself some dirty water (the cleaner the source, the better), a mug, cup, container, whatever, and a stack of coffee filters. Arrange the coffee filters on top of the cup, and start to slowly pour the dirty water in:
2 - Ensure that the filter doesn't fall into the cup so the water can't short circuit the filter. I folded the sides over. If you have another way to do it, say with a single cup over the mug coffee filter holder device, even better!
3 - You should have some clean looking water. Clean looking, but don't drink it yet! Also, please ignore the dirty dishes in the sink. I realize I'm a slob.
After you are done, you can let the coffee filters dry out for another run later. You can do this a number of times. You can even try rinsing the filters backwards to dislodge some dirt, or when it dries try prying them apart and gently shaking the dried dirt out. This works with strips of cloth as well. For me, I can't think of a filter cheaper, lighter or more plentifully available than coffee filters.
You're not done yet though. You still need to disinfect the water. This is done by bringing the water to a rapid, rolling boil for at least one minute. Or, if you still have some disinfectant tabs, use those. My favorite are the Katadyn micropur chlorine dioxide tabs, but eventually you will run out and will go back to boiling.
See? Easy, simple and cheap. Now go out there and make your water safe.
