In the contemporary era, when there are more concerns about water safety than it seems like ever before, purification is a central concern. It very well should be. The reasons for having water filters in the home are not simply about health, but they also have great benefits to the water's taste. This is important because it can be difficult to get the required amount of drinking water on any given day, and taste certainly helps. Outside the home, however, drinking tap water can be as questionable as it might be to drink the water while traveling abroad.
It's a good idea, then, to consider how travelers do it. Fortunately, finding pure water is not something new, and over the generations, people have found remarkably innovative ways to make it safe to drink or for cooking. Boiling has always been a popular favorite, because it's easy and also fairly sure. Outside of that, one of the oldest methods is to add iodine tablets , which can greatly reduce, if not eliminate, dangerous micro-organisms. These and other methods have been utilized and tested for generations, and every subsequent generation puts them to the test once again. They do work. While there's nothing like water drawn from one's own tap at home, these methods can help make other places seem a lot like home as well.
