Comments of chapter undefined of Survivors of the collapse

Haha. I'd stick with tap water or seek information from a professional. The methods I include throughout the story are based on experts I've researched online but I'd only do this in a survival situation. Especially since the water will still contain bacteria if you don't use purification tablets and most commercial filters you can buy simply can't trap viruses because of how small they are in comparison to bacteria which are much bigger in size.
