Best Water Filter for Chloramine
Chloramine tastes and smells like chlorine but resists the filters that remove chlorine.
Short answer
Use Catalytic carbon. Required for chloramine. Standard carbon barely touches it. Budget roughly $300–1,500 upfront and $100–250 a year in replacements (plumber recommended).
Regulatory context: EPA maximum residual disinfectant level 4.0 mg/L.
What actually removes chloramine
Many utilities switched from chlorine to chloramine because it lasts longer in the pipes — and that same persistence is why ordinary activated carbon barely touches it. You need catalytic carbon, a specific higher grade of media. If you bought a carbon filter for a chlorine smell and it did not help, chloramine is the usual explanation. Chloramine also will not dissipate by letting water sit out, unlike chlorine.
Works
- Catalytic carbonRequired for chloramine. Standard carbon barely touches it.
- Reverse osmosis (NSF 58)The broadest removal available at home: arsenic, nitrate, fluoride, PFAS, TDS.
Will not fix this
- Basic activated carbon (NSF 42)
- Ion-exchange water softener
- UV disinfection (NSF 55)

| SpringWell CF1 Whole-House CarbonWhole house | Catalytic carbon media, which is the grade required to reduce chloramine.Catch:Whole-house carbon protects showers and appliances but is not a substitute for a point-of-use lead or PFAS filter at the tap. | $900–1,400 | $0–100 | Check price |
| APEC ROES-50 EssenceUnder-sink | Built with WQA-certified components to NSF/ANSI 58.Catch:Needs an under-sink drain connection and a spare hole for the dedicated faucet. Strips minerals — some people dislike the flat taste. | $180–240 | $50–80 | Check price |

Check your own water before you buy
Filter shopping goes wrong in one predictable way: buying for a contaminant you don't have while missing the one you do. Your utility is required to publish detected contaminant levels every year, and those numbers tell you which row of the table above applies to you.
Frequently asked questions
What kind of water filter removes chloramine?
Catalytic carbon is the most reliable option: Required for chloramine. Standard carbon barely touches it. Typical cost is $300–1,500 upfront and $100–250 per year.
Does a basic activated carbon (nsf 42) remove chloramine?
No. Basic activated carbon (NSF 42) does not reduce chloramine to any meaningful degree, despite being the most commonly recommended filter type. Many utilities switched from chlorine to chloramine because it lasts longer in the pipes — and that same persistence is why ordinary activated carbon barely touches it. You need catalytic carbon, a specific higher grade of media. If you bought a carbon filter for a chlorine smell and it did not help, chloramine is the usual explanation. Chloramine also will not dissipate by letting water sit out, unlike chlorine.
Does boiling water remove chloramine?
Boiling addresses this contaminant, but it is a stopgap rather than a permanent solution. Many utilities switched from chlorine to chloramine because it lasts longer in the pipes — and that same persistence is why ordinary activated carbon barely touches it. You need catalytic carbon, a specific higher grade of media. If you bought a carbon filter for a chlorine smell and it did not help, chloramine is the usual explanation. Chloramine also will not dissipate by letting water sit out, unlike chlorine.
What is the EPA limit for chloramine?
EPA maximum residual disinfectant level 4.0 mg/L.
