What the USD uses
The district calls chloramine its standard combined disinfectant. It adds chlorine as sodium hypochlorite, according to its free chlorine FAQ, together with ammonia. The 2025 report's disinfectant table lists the result as chlorine, which reflects the total chlorine residual measured.
The free chlorine flush
Periodically the USD switches to free chlorine and flushes hydrants to remove biofilm from pipes. The district says this is typically done once or twice a year over two to four weeks; the 2025 flush ran July 1 to July 22. Expect a stronger chlorine taste or smell. The district suggests that people sensitive to the taste keep an open container of water in the refrigerator for a few hours to let chlorine dissipate. Dialysis patients, aquarium owners and restaurants with aquatic systems should check with their providers.
Why plain carbon may struggle
- Chloramine reacts slowly with ordinary carbon.
- It needs more contact time than small cartridges give.
- At around 3 ppm, small filters can be exhausted early.
That is why a pitcher that worked well in a city using free chlorine can seem to stop working after a move to Riviera Beach. It may still remove chlorine taste during a flush, then let chloramine through the rest of the year. The fix is not a bigger pitcher; it is media and contact time designed for chloramine.
What to look for
- Catalytic carbon or media designed for chloramine.
- A chloramine reduction claim on the exact model's NSF/ANSI 42 listing.
- Sizing to your peak flow.
Living Water describes its Puronics Clarius iGen and Goodspring whole-home systems as removing chloramine and chlorine.
Whole-home or kitchen
Whole-home covers showers and laundry; under-sink RO covers drinking water. See the chloramine filter guide.
Many households start with kitchen RO and add a whole-home system later if the shower smell still bothers them. Others do the reverse. Either order works, as long as each piece is chosen for chloramine.
