Byrd_Huntr...I'm not a hiker/camper and the Sawyer is just for hurricane season...they make adapters and bladders for just about any use...they state the .1 micron takes care of the bacteria and protozoa, but not viruses (I plan to use Clorox post filter).. it just filters particulates and not dissolved ions .. they make a .02 micron that will filter viruses... the filter comes with a syringe to back flush the hollow filter media...they claim a million gallons...I cut the hole in the bucket and pre fit the kit, then replaced it in the bag inside the bucket, and applied a piece of clear tape over the hole and stored it with the rest of the hurricane supplies... I've used their filter bottles in the past and was thouroughly satisfied... Sawyer is relatively local to me at Safety Harbor,Fla. , and Adventure Safety is probably their internet outlet just down the road in Oldsmar, Fla...Adventure Safety was recommended to me when I called Sawyer...
