Can Hexavalent Chromium be filtered from water?

Faucet and countertop filters using activated carbon are not capable of removing or reducing Hexavalent Chromium. Water purification (reverse osmosis), not just simple filtration, will remove Hexavalent Chromium from drinking water.

How is Hexavalent Chromium removed from drinking water?

Reverse Osmosis will remove Hexavalent Chromium from drinking water.

Is chromium harmful in drinking water?

It is not harmful unless levels are very high. Chromium 0 and VI are more harmful and there are health risks with exposure. People who drink water with chromium over the maximum acceptable concentration (MAC) for many years can have health problems like: allergic dermatitis.
