- daniel_reetz 4y agoPaper coffee filters do not effectively remove lead. Distillation and reverse osmosis remove lead.
- mint2 4y agoThat is incredibly wrong and dangerous advice. There were studies that showed coffee grounds could be used to filter substantial but not all lead, is that what you misremembered?
- Alex3917 4y agoI was remembering this: https://www.wired.com/2000/02/coffee-is-your-friend/ https://www.wired.com/2000/02/coffee-is-your-friend/ "A group of international scientists found that coffee filters can remove from 78 to 90 percent of dissolved heavy metals such as lead and copper from tap water." It looks like the quote is incorrect though, and it is actually the the ground coffee and not the paper filter that's removing the lead. Regardless, brewing ground cacao in the same way would likely also filter out some of the lead by the same mechanism, even if not as much. (Since the source of lead is embedded throughout the ground beans, rather than coming from the water which enters at the top of the column.)
