Which do you have?
Many Florida utilities disinfect with chloramine, and some still use chlorine. Your utility's annual water quality report (the Consumer Confidence Report) says which it uses, or you can call the number on your water bill. If the water smells less like a swimming pool than you'd expect but carbon pitcher filters don't seem to help, chloramine is a likely reason.
Why it matters for a filter
- Standard carbon removes chlorine quickly but chloramine slowly.
- Catalytic carbon is made to break down chloramine, and the tank has to be big enough for the water to spend time in it.
- Small pitcher and fridge filters are usually rated for chlorine taste, not chloramine; check the product's certification.
Other places it shows up
If you keep fish, ask your pet store about dechlorinating water for chloramine; it needs a different conditioner from chlorine. Your utility's annual water quality report says which disinfectant it uses.
Short answers
How do I know if my water has chloramine?

Does boiling remove chloramine?
Not quickly. Chloramine is more stable than chlorine, which is why utilities use it, and it takes a long boil to drive off.
