Activated charcoal (or activated carbon) is far more effective for filtering water or air than powdered charcoal. It's what is used in systems that filter tap water, aquarium tanks, etc. I use it as part of the fume extraction system for my laser cutter/engraver. I have not had to buy any activated charcoal yet, but I understand that you can buy 50 lb. for just over $100 if you shop around. Smaller quantities can be pretty expensive but you can buy the stuff off of eBay.

^I wanted to remind everyone that I think you could actually just buy a good water filter instead of buying activated charcoal and having to make the water filter for yourself. But make sure that it will filter out chemicals.

I greatly apologize for not mentioning that earlier. If you've been reading my posts, you'll notice that I don't point out anything that I think you should buy. This is because I have a fear that I'll tell you guys, "Buy this!" and then I'll later learn that you shouldn't have bought it. I understand that all of you work hard for your money, and that's why I have a fear of giving you advice on what you should buy. I have a fear that you'll pay $100 on something, and it'll turn out that you shouldn't have bought that. I'll try my best to give advice on what you should buy, but please do your own research and find out yourself on what you should do with your money.

I would like to go ahead and explain to all of you the different edible plants that you can get in the wild, prepare, and eat since it's convenient to. But if all of you don't mind, I'll show these first two videos and I'll post the other videos when I have more time.
