I would probably want a Gravi-stil as relying on filter mediums has a built-in expiration date (or # of gallons).


Sure, but even with my regular water usage, the LifeStraw Max filters would last me over a year, and it works via water pressure. There isn't really any disaster scenario where I'm remaining in my home and need to purify water via burning wood.
