I'm using the ceramic white filters with PF-4 fluoride filters

Cut and paste:

PF-4 reduction elements, are designed to adsorb the following four unwanted elements most commonly found in drinking water.

- MTBE (Methyl-tertiary-butyl-ether)
- Fluoride
- Lead
- Arsenic

PF-4 filters are also designed to adsorb:

- DBCP (Dibromo-chloro-propane)
- THMs (trihalomethanes)
- Herbicides & Pesticides
- Heavy Metal ions

Note: The PF-4 shell is made from safe, non-leaching Polypropylene #5, that is BPA-Free and is used for food items such as ketchup bottles and yogurt containers.
