>>901773Iodine is fantastic for quicker treatment. Still need to let it sit but it's quicker than boiling.
You can also use iodine to treat wounds. In planning a backpack or really anything it is good to have multiple uses in mind.
My backpack has a geigerrig bladder with two virus filters, a 1 micron bag filter (might get a half micron in the future, but neither is 100% so this is just to filter particles out anyway). Then I have iodine and alcohol if needed, I carry some 191 because it is a great fire starter, can clean the water, and is a worst case scenario antiseptic. Alcohol isn't great for treating wounds, but it's better than nothing. It has many more uses I haven't even touched on.
I also have a pot for boiling water, fits around my bottle.
My pack has enough room for at least 2 days of high water consumption between the bladder and bottle.
solar stills are easy as hell but won't work well in my area in the winter, not enough light usually. You can also just tie bags around trees and try to capture water from the tree, this is clean minus anything that might be on the tree where you bagged it (don't bag bird shit lol)
You can live hungry a lot longer than you can thirsty, and there isn't much safe water in this world anymore...
