Water is one of the most important parts of being a survivalist. You simply cannot survive without water, and if the water system is down, you have to find a way to purify water so you can drink it. Commercial water filters are an excellent way to purify water, and they are easy to include in your emergency kit.
How Commercial Water Filters Work
These filters contain a hose that water passes through a purifier, and then a filter. By the time the water makes it out of the filter, it is safe to drink. You can find these in various styles, but most will get the job done with ease.
Be sure to check what impurities the filter filters out before purchasing it, though. Depending on the disaster, you might not just be fighting against bacteria. You also might have to contend with viruses, so keep that in mind when purchasing a filter.
