So last night I went to the fridge to get a glass of water. I recently got married and one of the gifts that we got was a brita water filter jug and grabbed it from the fridge to fill my glass. I then started wondering if it is wise to prep extra filters to have on hand for a method of water filtration in a SHTF scenario. Anyone have any ideas or concerns about this method? Just thought I'd throw it out there to see if anyone else has thought about this or done this already...
