When it comes to making water safe for human consumption there are many different options. First, everyone should have some sort of filtering method to keep in their emergency kits such as Survivor Filters straw or Pro pump model which I have personally used and tested myself or some purifying tabs like Aquatabs. There are also many other options like making a basic filter out of everyday items such as a bandana, tee shirt, or even a coffee filter to eliminate any large debris and then boiling the water as well to kill any harmful bacteria. There are also many natural ways to create your own filters using rocks, sand, charcoal, and grass in conjunction with a 2 liter bottle Which you can also use to store water) or anything to hold these materials to make a slow drip style filter, you always should boil this water after filtering. You can also us bleach to help keep water during long term storage, which there is a ratio chart listed below for that. There are many ways to purify water but make sure you and your family have what you need to survive and that is 1 gallon per person per day, for a minimum of 3 days.
Pictured above and to the left are a few improvised methods to purify water. The two pictured above use natural materials which are gravel, sand, and charcoal to filter water and either a 2 liter bottle or something similar or some cloth to hold the materials. The solar still you will just need a clear sheet of plastic, a pan, a hose, and some rocks. This method can be used with salt water as well.
Check out my video on how to filter dirty water to make it clean using only a strip of a tee shirt. This water should still be boiled in my opinion and this method does take some time, so don't be in a hurry if you try this method!
