There are several things that we need daily to survive, and water is one of the most important ones. Odds are that there will be times and situations in your life where you don't have access to clean drinking water, like during a horrific storm, or if you get stranded somewhere, so why not try and stay prepared. Now, we aren't talking about stockpiling jugs of water or doing anything overly crazy, but instead just making a $10 investment towards ensuring you are never without it.

Right now you can pick up the LifeStraw Personal Water Filter for $9.99 at Amazon, which is a savings of $5 from its regular price.

The LifeStraw is capable of removing a minimum 99.9999% of waterborne bacteria, which surpasses the EPA standards for water filters. With it, you can filter 1000 liters of contaminated water without using iodine, chlorine, or other chemicals. It comes in a sealed bag so you can keep it around and use it when you need it most. It may seem like a silly purchase today, but when you need to use it you'll be very happy that you bought one.
