RO filters should. It looks like charcoal as well, assuming you replace your filter on schedule. https://www.health.state.mn.us/communities/environment/hazard

  FYI: charcoal filters can introduce arsenic and also appear to increase the bacteria in the filtered water.

    The arsenic is no longer true: "since Oct. 15, 2009, no company is allowed to manufacture, distribute, ship or sell any products that leach arsenic in concentrations greater than 5 parts per billion (ppb)" [1] And bacteria growth is solved by following the manufacturer's directions. For example, Brita filters in use need to be kept in the fridge and changed every 2 or 3 months.

      I assume this is true for 1) filters that are NSF certified and 2) wish to not display a prop 65 warning. A majority of the water filters purchased on Amazon are not NSF certified and ship with a prop 65 warning. In fact, it's difficult to purchase water filter components that do not have a prop 65 warning.

  Glad to hear charcoal works. Picked up a Berkey filter years ago because a family member was insistent.

    Charcoal filters have a relatively short lifespan.
