What Seacoast reports
Seacoast's 2025 Annual Water Quality Report lists chloramines at 3.7 ppm, with results from 3.6 to 3.8 ppm against a maximum of 4. The report notes chloramines minimize disinfection byproduct formation, give the water a better taste than free chlorine, and must be removed from water used for kidney dialysis and in fish tanks or aquariums. Byproducts were low: TTHM 7.9 ppb and HAA5 6.5 ppb.
A narrow, steady range like that means your filter will face roughly the same load all year.
Why chloramine is harder to filter
Standard carbon removes free chlorine quickly. Chloramine reacts more slowly, so it needs a catalytic carbon or similar media and enough contact time. Small pitchers and faucet filters may reduce chlorine but not chloramine to the same degree.
Certification to look for
- NSF/ANSI 42 includes chloramine reduction as an aesthetic claim; check that chloramine, not just chlorine, is on the listing.
- Match the exact model number on the certifier's listing.
- Check the rated capacity against your household's water use.
Whole-home vs. drinking water only
- Whole-home: treats showers and laundry too. Living Water describes its Puronics city water systems as removing chloramine and chlorine.
- Under-sink RO: carbon prefilters handle chloramine for drinking water only.

Aquariums and dialysis
Follow Seacoast's advice: aquarium keepers should use a conditioner labeled for chloramine, and dialysis patients should follow their physician or dialysis specialist. A home filter does not replace those instructions.
How chloramine behaves in your home
Because chloramine is stable, it stays in the water through your pipes, water heater and fixtures. You may smell it more in a hot shower, where it vaporizes. Seacoast's data shows very little variation across its system, so homes at the edge of Lake Park and homes closer to the plant should see similar levels. A tap test confirms what your house gets.
If you ever notice a stronger chlorine smell for a period, check Seacoast's notices; utilities sometimes adjust disinfection for maintenance.
Signs your filter needs service. The first sign is usually the return of the pool-like smell at the kitchen tap or in the shower. A simple total chlorine test before and after the system shows whether the media is still working. Ask your installer how often to test.
