Can You Purify Water Just by Boiling It?

Should it then be activated by soaking in lemon juice afterwards, then dried in the sun, or is the biochar naturally activated to attract chemicals to itself, as some have claimed?

...

I think that, regardless of what people say, just to remain on the side of caution using the activation process on it could not hurt it, and may or may not help, but it would be the more cautious course of action.

I just read that natural hardwood charcoal, which can be bought at the hardware store for a reasonable price, is naturally porous and would be able to capture chemicals/impurities so it looks like no other treatment is needed.

I don't want to use precious resources if I don't have to.

I watched one guy tamp/smash the store bought charcoal to smaller pieces, then ground them up further using a mortar and pestle to use for filtering water. I think this is the way I will be doing it.
