Chloramine in Water
The short answer on chloramine
Chloramine (chlorine + ammonia) is the *other* municipal disinfectant — serving on the order of one in five Americans and trending up because it's more stable in long mains. The catch that matters at your sink: standard granular activated carbon underperforms on chloramine — it works, slowly and poorly, and exhausts fast. The correct media is catalytic carbon (look for an NSF/ANSI 42 claim that na… The details — sources, official limits and honest removal methods — are in the complete guide: The complete chloramine guide.
How to remove chloramine — what actually works
| Technology | Where it lives | What to demand on paper |
|---|---|---|
| Catalytic Carbon | Point-of-use or whole-house system per spec | Named NSF/ANSI protocol or third-party lab sheet for the exact model |
If a listing claims chloramine reduction and cannot name the standard or show the lab sheet, assume it does not have one. That single check filters out most of the market.
Can your refrigerator filter handle chloramine?
Only catalytic carbon does; standard GAC that handles chlorine fine does little to chloramine. Fridge cartridges are built for chlorine, taste and odor (NSF/ANSI 42), plus lead and cysts on certified 53 tiers. If chloramine is your concern, keep the fridge cartridge for what it does well and put the right technology where you drink: see what your fridge model takes, then match the removal stage to the contaminant.

Chloramine questions, answered straight
Does boiling water remove chloramine?
Boiling is a concentration step, not a filter: water leaves as steam and whatever is dissolved stays behind, so levels rise by roughly the volume lost. The only heat-based method that works is distillation — capturing and condensing the steam. For chloramine specifically, see the full guide.
Is my refrigerator water filter enough for chloramine?
Only catalytic carbon does; standard GAC that handles chlorine fine does little to chloramine. Match the technology to the contaminant, not the badge on the box.
How do I find out my actual chloramine level?
On city water, your utility's annual Consumer Confidence Report lists it free. On a well, a lab mail-in panel is the reliable route — the test-first card above links our guide to reading the results.
What removes chloramine from drinking water?
The technologies with a track record for chloramine: catalytic carbon. Claims worth having come with a named standard (NSF/ANSI protocol or third-party lab sheet) — buy where the certificate names the exact part number.
