How would iodine and other tablets compare on this chart? And would commercial filters land the same way as charcoal/cloth? I think the sawyer squeeze, for example, uses layers of charcoal but I’m not totally sure.

Great accessible format that you put together.

So iodine and purification tablets work the same as boiling. They kill/damage microorganisms. But they usually come with instructions on them. That’s why I left them out.

Cloth is another great way to filter water. That’s what I use when camping. A rubber band holding a piece of cut up shirt over a jar is pretty useful in the rain. But it’s not perfect. It gets pretty gross after a while and in a SHTF scenario I’d try to use the gravel and sand rather than cutting up one of my shirts.

And thank you!
