Water Filter Basics
One of the most important items that you can have in your emergency supplies is a water filter. There are a variety of ways to clean water and make it safe to drink: boiling, distillation, reverse osmosis, deionization, chemical purification and filtration. In this post, I want to explain the basics of micro porous filtration or more simply said “how a water filter works”. At the end of the post, I have included some excellent reference articles from Wikipedia that include more detailed information on the topic for those that are interested.
