What Seacoast says about chloramine
Seacoast's report explains that chloramines are a federally approved alternative to free chlorine, that they minimize disinfection byproduct formation and that they can taste better than free chlorine. Its 2025 byproduct numbers are low: haloacetic acids 6.5 ppb and trihalomethanes 7.9 ppb, against limits of 60 and 80. It also says chloramines must be removed from water used for kidney dialysis and in fish tanks and aquariums.
A steady, fairly high residual
Some utilities report wide swings in disinfectant levels. Seacoast's 2025 monthly chloramine results stayed between 3.6 and 3.8 ppm. For a homeowner, that means two things: the level you notice is consistent, and a filter must be sized for it all year rather than for occasional peaks.
Why plain carbon may struggle
Free chlorine reacts quickly with activated carbon. Chloramine is more stable and needs more contact time; catalytic carbon is commonly used. A faucet, pitcher or shower filter that handles chlorine well may reduce chloramine only partly. More in chloramine in city water: choosing a filter.
The same contact-time issue affects RO pre-filters and refrigerator filters.
What to look for
- A specific chloramine reduction claim listed under NSF/ANSI 42.
- The exact model on the certifier's listing.
- Rated service flow that matches your home's peak use.
- A media replacement schedule based on chloramine.
Living Water describes its Puronics Clarius iGen and Goodspring city water systems as removing chloramine and chlorine.
Ask how you will know when media is spent. Some systems use a set schedule; others rely on testing.
Aquariums, ponds and dialysis
Waterfront homes often keep aquariums or fish ponds. Ask a pet store or aquarium professional how to treat water for them. For dialysis, talk to your physician or dialysis provider. A household filter is not a substitute for their guidance.
Whole-home or kitchen, and a tap test
A whole-home system takes chloramine out of showers and laundry; under-sink RO handles drinking water in any home, including condos. Jorge measures chloramine at your tap during the free test. Call, text or WhatsApp (305) 793-5974.
He checks hot and cold taps, since water heaters change what you measure, and explains what the readings mean for the filter choice.
