Solar Disinfection, or SODIS for short, is a super simple way to clear water of pathogens. For some reason it doesn't some up often when looking at water purifcation methods. You usually find the standard; boiling, chemical tablets, carbon/ceramic filtration advice, but rarely do you see the SODIS method. Actually it is similar to using artificial UV disinfection. In this case however, the UV rays are coming from the sun!

If you are just starting out with your water storage and preparedness, you'll notice that there's lots of information and products concerning water purification and filtration.

Although both processes remove contaminates from the water, they are not the same and should not be used interchangeably, although they often are.

So in this article I just wanted to cover some of the basics of what the differences are between the two, and when you are most likely to use one or both of these methods to clean your water.
