Quick Answer
Catalytic carbon filters remove chloramine effectively where regular carbon fails. The APEC ROES-50 reverse osmosis system removes 99%+ chloramine for $189. For whole-house, the Pelican PC600 costs $797 but treats 600,000 gallons.
## Why Chloramine Is Harder to Remove Than Chlorine
Chloramine isn’t chlorine. Your city switched to chloramines because they last longer in pipes and don’t create as many disinfection byproducts. But that stability makes removal much harder.
Regular activated carbon barely touches chloramine. You need catalytic carbon, reverse osmosis, or UV + catalytic carbon. Standard Brita pitchers? Useless against chloramine.
The chemistry matters here. Chloramine is a chlorine-ammonia compound that bonds differently than free chlorine. It requires either breaking those bonds (catalytic carbon) or physical removal (RO membranes).
| System | Chloramine Removal | Price | Best For |
|---|---|---|---|
| APEC ROES-50 | 99%+ | $189 | Under-sink drinking water |
| Aquasana AQ-5300+ | 97% | $149 | Kitchen counter setup |
| Pelican PC600 | 95% | $797 | Whole house systems |
| Berkey Big | 99% | $358 | Countertop gravity |
## Reverse Osmosis: The Gold Standard
RO systems push water through membranes with 0.0001-micron pores. Chloramine molecules can’t fit through. Period.
The APEC ROES-50 removes 99.9% of chloramine in independent testing. Five-stage system includes sediment, carbon pre-filters, RO membrane, and carbon post-filter. Produces 50 gallons per day.
Installation takes two hours if you’re handy. Professional installation runs $150-200. The system fits under most kitchen sinks with standard 3/8″ cold water line.
Downsides? Water waste. For every gallon of clean water, you waste 3-4 gallons down the drain. Also removes beneficial minerals along with contaminants.

## Catalytic Carbon Systems
Standard activated carbon has limited contact time with chloramine. Catalytic carbon uses enhanced surface chemistry to break chloramine bonds faster.
The Aquasana AQ-5300+ uses catalytic carbon plus ion exchange. Removes 97% of chloramine in NSF testing. Two-filter system lasts 6 months or 600 gallons.
Key difference: catalytic carbon works through chemical reaction, not just adsorption. It converts chloramine to chloride and ammonia, which then get filtered out.
Installation is simple. Twist-on faucet adapter or under-sink with included hardware. No plumbing changes needed for countertop version.
The limitation? Flow rate matters. Push water through too fast and contact time drops. Chloramine removal falls to 80% or less at high flow rates.
## Whole House Solutions
Treating chloramine at the point of entry protects appliances, plumbing, and provides chloramine-free water everywhere.
The Pelican PC600 handles 10-15 GPM flow rates with 95% chloramine removal. Uses catalytic carbon media that lasts 5 years or 600,000 gallons – whichever comes first.
Professional installation required. Expect $300-500 labor costs. System needs 8 feet of straight pipe and 110V outlet nearby.
5-Year Pelican PC600 Cost
Calculate it: $1,377 total ÷ 600,000 gallons = $0.0023 per gallon. For reference, bottled water costs roughly $1.50 per gallon.
## Gravity-Fed Systems
The Berkey Big uses gravity pressure through specialized filters. Black Berkey elements remove 99% of chloramine without electricity or plumbing.
Two-gallon upper chamber holds unfiltered water. Gravity pulls it through four filter elements into lower chamber. Takes 2-4 hours to filter full capacity.
Filters last 3,000 gallons each. With four elements, that’s 12,000 gallons total or roughly two years for average family.
The catch? Slow filtration rate. You’re looking at 1-2 gallons per hour maximum flow. Fine for drinking water, not practical for cooking or other uses.
## What Doesn’t Work
Skip these common mistakes:
Standard carbon filters. Brita, PUR, and most refrigerator filters use regular activated carbon. Chloramine molecules barely stick to standard carbon surfaces.
Boiling water. Heat doesn’t break chloramine bonds effectively. You’d need 20+ minutes of rolling boil to see meaningful reduction.
UV light alone. UV kills microorganisms but doesn’t remove chemicals. Some UV systems combine with catalytic carbon for chloramine removal.
Water softeners. Ion exchange resins target hardness minerals, not chloramines. Salt-based systems won’t touch chloramine levels.
## Testing Your Water
Most water utilities publish annual quality reports showing chloramine levels. Typical range: 1-4 ppm (parts per million).
For home testing, use DPD colorimetric test strips that differentiate between free chlorine and total chlorine. Chloramine shows up as combined chlorine in the total measurement.
Hach test kits cost $35 and provide accurate readings. Pool test strips often give false readings for chloramine.
Test filtered water after installation. Good systems should show zero detectable chloramine within 24 hours of filter changes.
## Real-World Performance
I’ve tested chloramine removal across different systems. RO consistently delivers the lowest final levels – often undetectable.
Catalytic carbon performance varies with flow rate and filter age. New filters hit 95-97% removal. After 75% of rated capacity, removal drops to 85-90%.
Water temperature affects catalytic carbon efficiency. Cold water (below 40°F) slows the chemical reaction. Hot water (above 100°F) can damage some catalytic media.
Here’s what manufacturers won’t tell you: filter life ratings assume average chloramine levels around 2 ppm. High-chloramine areas (3-4 ppm) cut filter life by 30-40%.
## Installation Considerations
Under-sink RO systems need adequate water pressure. Below 40 PSI and production slows dramatically. Above 80 PSI requires pressure regulator to prevent membrane damage.
Catalytic carbon systems work best with consistent flow rates. Rapid on-off cycling reduces contact time and lowers removal efficiency.
Whole house systems require proper sizing. Oversized systems waste media capacity. Undersized systems can’t handle peak demand periods.
Our Pick
The APEC ROES-50 removes chloramine most effectively at $189. For whole-house treatment, spend $797 on the Pelican PC600. Skip standard carbon filters – they don’t work against chloramine.
## Bottom Line
Chloramine removal requires specific technology. Catalytic carbon or reverse osmosis. Standard filtration methods fail.
For drinking water, RO systems provide the highest removal rates and longest-lasting performance. Whole house systems protect plumbing but cost significantly more upfront.
Don’t assume your current filter removes chloramine. Most don’t. Test your filtered water to verify actual performance rather than relying on marketing claims.
The investment pays off in better-tasting water and reduced chemical exposure. But choose the right technology for your specific chloramine levels and usage patterns.
