- They have the benefit of filtering out heavy hitters like:
- Barium – health risks in water
- Bromodichloromethane – health risks in drinking water
- Chloroform – side effects
- Chromium (total)
- Haloacetic acids – chlorination byproduct*
- Hexavalent chromium – health effects
- Total trihalomethanes – byproduct of chlorination*
*Chlorination is an effective method of disinfecting/treating drinking water. You can then use a water filter to reduce the effects of chlorination byproducts to get the safest, cleanest water possible.
