In another thread, two forumites mentioned they were making inexpensive bucket-based water filters. One source was mentioned here. This is the coolest idea, I would like to make one, too. Those of you who've made this kit: - How do I get started? - Is this a water filter, or water purification system? I'm assuming filter (meaning effective against bacteria and protozoan cysts, but not viruses). So does this require additional treatment? Wanna kill these ads? We can help!
