The numbers from both reports
| Jupiter (2025) | Seacoast (2025) | |
|---|---|---|
| Chloramines | 2.99 ppm highest running average | 3.7 ppm |
| Individual results | 0.6 to 4.4 ppm | 3.6 to 3.8 ppm |
| Limit | 4 ppm | 4 ppm |
Seacoast notes chloramines are a federally approved alternative to free chlorine that minimize byproduct formation and must be removed for kidney dialysis and aquariums.
Why plain carbon may struggle
Free chlorine reacts quickly with activated carbon. Chloramine is more stable, so it needs more contact time, and catalytic carbon is often used. A faucet or pitcher filter that handles chlorine well may only partly reduce chloramine. More in chloramine in city water: choosing a filter.
The same issue affects RO pre-filters, refrigerator filters and shower filters: short contact time means less chloramine reduction.
What to look for
- A specific chloramine reduction claim, listed under NSF/ANSI 42.
- The exact model on the certifier's listing.
- Rated flow that matches your peak use for whole-home systems.
- A media replacement schedule based on chloramine, not just chlorine.
Living Water describes its Puronics Clarius iGen and Goodspring city water systems as removing chloramine and chlorine.
Ask whether the system's media replacement schedule is based on chloramine levels like those in Juno Beach, and how you will know when it is time to replace.
Aquariums and dialysis
Both utilities note chloramine must be removed for fish tanks and kidney dialysis. Ask a pet store or aquarium professional about tank water, and your physician or dialysis provider about dialysis water. A home filter is not a substitute for their guidance.
Some households keep a small dechlorinating product for aquarium water changes even with a filter, because guidance for fish is specific.
Whole-home or kitchen
In a house, a whole-home system removes chloramine from showers and laundry. In an oceanfront condo, under-sink RO plus shower filters is the usual route.
Many households do both: a whole-home system for showers and laundry, and kitchen RO for drinking and cooking water.
Measure it at your tap
Jupiter's individual results range widely, from 0.6 to 4.4 ppm. Jorge measures chloramine at your tap during the free test. Call, text or WhatsApp (305) 793-5974.
He also checks hot and cold taps, since water heaters change how chloramine behaves, and explains what the numbers mean for the filter choice.
