How to Compare Water Filter Pitchers for Chloramines

You bought a pitcher, filled it, and the water still tastes faintly of the pool. You assumed any filter handled tap water, so the lingering chemical note is baffling, until you check your city’s water report and find one word that explains it: chloramine. Your filter was built to tackle chlorine, and the two are not the same problem. The pitcher is doing its job; it was just never designed for the job your water actually needs.

Choosing a water filter pitcher for chloramines is a different task from picking one for chlorine, and skipping that distinction is why so many pitchers disappoint. Many cities now treat water with chloramine, a tougher compound that ordinary carbon filters struggle to remove, so the pitcher that works for your neighbor may do nothing for you. Here is how to confirm what your city uses, the single certification claim that matters, and how to compare pitchers that genuinely handle chloramine.

Quick Take

• Chloramine is harder to filter than chlorine, so a standard pitcher rated only for chlorine taste and odor may barely reduce it.
• Look for a filter specifically certified to reduce chloramine under NSF/ANSI 42, or one built with catalytic carbon, not ordinary activated carbon.
• Confirm your city uses chloramine first, then compare pitchers on that chloramine claim, filter life, and how fast they pour.

Why Chloramine Is Harder to Filter Than Chlorine

Chloramine is chlorine combined with ammonia, and many utilities use it because it stays stable in the pipes far longer than free chlorine. That stability is exactly what makes it stubborn to remove. Ordinary activated carbon, the media in most basic pitchers, is good at pulling out chlorine and its taste, but it reduces chloramine slowly and needs much more contact time to do it. The fix is catalytic carbon, a treated form of carbon that reacts with chloramine rather than merely adsorbing it. If a pitcher’s filter is plain carbon rated only for chlorine, expect it to leave most chloramine behind.

First, Confirm Your City Uses Chloramine

Before shopping, find out what is actually in your water. Your utility publishes an annual water quality report, often called a Consumer Confidence Report, that states whether it disinfects with chlorine or chloramine, and you can usually find it on the utility’s website or by calling them. The EPA’s overview of chloramines in drinking water explains why systems use it. Knowing your disinfectant turns filter shopping from guesswork into a targeted search, since a chloramine city and a chlorine city need different filters.

The Certification That Actually Matters

This is where most people go wrong. Filters carry NSF/ANSI certifications, and NSF/ANSI 42 covers aesthetic reduction, taste and odor, including chlorine. The catch is that chlorine reduction and chloramine reduction are separate claims: a filter can be NSF 42 certified for chlorine and do little for chloramine. So do not stop at “NSF 42 certified.” Look for a filter specifically listed as reducing chloramine, and favor products that state they use catalytic carbon. That one line in the specs, chloramine reduction, is the difference between a pitcher that solves your problem and one that only looks like it should.

What to Compare Across Pitchers

Once you are looking at chloramine-capable pitchers, weigh them on these points:

• The chloramine claim. Is chloramine reduction explicitly certified or tested, and to what percentage, rather than merely implied by a general carbon filter?
• Filter media. Catalytic carbon, or a multi-stage system, handles chloramine far better than plain activated carbon.
• Filter life. Chloramine-capable filters often have a rated gallon capacity; a shorter life means more frequent, costlier replacements.
• Flow speed. Thorough filtration is slower, so a pitcher that removes more may pour more slowly, which matters for a busy household.
• Cost per gallon. Divide the replacement filter price by its rated gallons to compare the real running cost, rather than the sticker price alone.

How the Popular Pitchers Stack Up

Not every well-known pitcher targets chloramine. Clearly Filtered’s pitcher is built for it, advertising very high chloramine reduction and certification against several NSF standards, which makes it a strong choice for a chloramine city. Waterdrop offers pitcher models specifically marketed for chloramine reduction under NSF/ANSI 42, and Epic’s pure-line pitchers also claim chloramine reduction. ZeroWater’s multi-stage system reduces a broad range of contaminants and dissolved solids, though its filters pour slowly and exhaust quickly. By contrast, standard Brita and PUR carbon pitchers are generally rated for chlorine rather than chloramine, so verify the specific model’s claim before assuming it helps. Always confirm the current certification on the exact model you are considering.

When a Pitcher Isn’t Enough

If your water is heavily chloraminated or your household drinks a lot, a pitcher may not keep up. Catalytic carbon needs contact time, and a small pitcher filter offers less of it than a larger system. In that case, an under-sink or faucet-mounted catalytic carbon filter, or a reverse osmosis system, provides more thorough and consistent chloramine removal with less frequent refilling. Those cost more and may need installation, but for a chloramine-heavy supply they can be worth it. Start with a certified pitcher to see whether it satisfies your taste and needs, and step up only if it does not.

Frequently Asked Questions

Does a Brita filter remove chloramine?

Most standard Brita pitchers are certified to reduce chlorine taste and odor, not chloramine, so in a chloramine city they typically leave much of it behind. Chloramine needs catalytic carbon and more contact time than a basic carbon filter provides. Some manufacturers offer specific models or filters that claim chloramine reduction, so the safe approach is to check the exact model’s certification for a chloramine claim rather than assume the brand covers it. If it only lists chlorine reduction, it is not the right filter for chloraminated water.

How do I know if my water has chloramine or chlorine?

Check your utility’s annual water quality report, sometimes called a Consumer Confidence Report, which states the disinfectant used. It is usually posted on the water provider’s website, and you can call them to ask directly. Some home test kits also distinguish total from free chlorine, which hints at chloramine, but the utility’s report is the simplest reliable answer. Knowing your disinfectant is the essential first step, because a filter that is perfect for chlorine may do little for chloramine, and the label alone will not tell you what your tap actually contains.

What is catalytic carbon and why does it matter for chloramine?

Catalytic carbon is activated carbon that has been treated to be more chemically reactive, which lets it break down chloramine rather than just adsorbing it the way ordinary carbon does. Because chloramine is stable and slow to remove, this reactivity, plus enough contact time, is what makes effective reduction possible. When you compare filters, a stated use of catalytic carbon, or a specific certified chloramine-reduction claim, signals the filter can actually handle chloramine. Plain activated carbon without such a claim is the media most likely to underperform on chloraminated water.

Is a pitcher or an under-sink filter better for chloramine?

A certified pitcher can work for light use, but an under-sink or faucet catalytic carbon filter, or a reverse osmosis system, generally removes chloramine more thoroughly and consistently. Larger systems give the water more contact time with the media and need refilling far less often, which suits heavier chloramine or a household that drinks a lot of water. Pitchers win on price, portability, and no installation. A reasonable path is to try a certified chloramine pitcher first, then upgrade to an installed system only if the pitcher cannot keep up with your taste or volume.

Match the Filter to Your Water

The reason a pitcher can leave your water tasting off is rarely a defect; it is a mismatch between chlorine-rated carbon and chloramine-treated water. Confirm what your city uses, then shop for a filter that specifically claims chloramine reduction or uses catalytic carbon, and compare the real running cost by dividing filter price by rated gallons. For light use a certified pitcher may be plenty, and for heavy chloramine an under-sink or reverse osmosis system is the sturdier answer. Match the filter to your actual water, and the pool-water taste finally disappears. For more on improving your home’s essentials, browse Wayodd’s Home Improvement section.
