If your tap water smells like a swimming pool, you are tasting chlorine, and the good news is that it is one of the easiest things to filter out. We have tested filters across every form factor, and almost all of them improve chlorine taste noticeably on the first glass.

The harder problem is chloramine, a longer-lasting disinfectant that a growing number of US cities now use. It does not off-gas the way chlorine does, and it slips past cheap carbon, so it needs the right media and enough contact time.

This guide sorts out that distinction in plain language, then gives you six picks across whole-house, under-sink, faucet, pitcher and shower filters. We checked each one against the NSF and IAPMO certification databases so you are not relying on marketing claims.

Chlorine vs chloramine, and what actually removes them

Chlorine is added to kill bacteria, and it is volatile, meaning it evaporates over time. A glass of tap water left on the counter overnight will lose much of its chlorine on its own. That same volatility is why activated carbon grabs it so easily.

Chloramine is chlorine bonded with ammonia. Utilities like it because it stays stable all the way through the pipes to your house, which is great for safety but bad for filtration. It does not evaporate, and standard carbon only breaks it down slowly.

That slow breakdown is the whole story. Plain activated carbon can technically reduce chloramine, but only with a lot of contact time. At the flow rate of a kitchen faucet, regular carbon often lets chloramine pass through.

The fix is catalytic carbon. It is activated carbon that has been treated, usually with heat and gas, to make its surface far more reactive, so it neutralizes chloramine much faster. Whole-house systems built for chloramine pair catalytic carbon with a large media bed to maximize contact time.

So the rule of thumb is simple. If your city uses free chlorine, any decent carbon filter will fix the taste. If it uses chloramine, look specifically for catalytic carbon and a system designed for the longer contact time.

What NSF certification to look for

For this category, the certification that matters is NSF/ANSI 42, which covers chlorine taste and odor reduction. If a filter is certified to Standard 42 for chlorine, an independent lab has verified the claim.

NSF/ANSI 53 is a separate, health-focused standard for contaminants like lead, cysts and certain chemicals. Many good carbon filters carry both. Note that very few products carry a dedicated chloramine certification, so for chloramine we lean on catalytic carbon media plus the manufacturer's own tested reduction figures.

Choosing the best water filter for chlorine for your home

The best water filter for chlorine depends less on the spec sheet and more on where you want clean water. If you only care about drinking water taste, a pitcher or faucet mount is cheap and works in minutes.

If you want filtered water for the whole kitchen without thinking about it, an under-sink unit is the sweet spot. And if you have chloramine, dry skin in the shower, or you want every tap covered, a whole-house catalytic carbon system is the right tool even though it costs more.

Our top picks at a glance

• Best overall: Aquasana Claryum AQ-5200 under-sink, NSF certified and fast.
• Best for chloramine: Aquasana Rhino Chloramines whole-house with catalytic carbon.
• Best value under-sink: Frizzlife MK99, certified and easy to install.
• Best faucet mount: PUR Plus, three-in-one filter at the tap.
• Easiest pitcher: Brita Elite, six-month filter life.
• Best shower filter: AquaBliss SF100 for chlorine and skin.
• Budget pick: ZeroWater 10-cup with a TDS meter included.

Aquasana Claryum AQ-5200 under-sink filter

This is our overall pick because it nails the most common goal, great-tasting chlorine-free water at the kitchen sink, without the bulk or cost of a whole-house system. The full system is WQA tested and certified to NSF/ANSI Standards 42, 53 and 401.

The two-stage Claryum media reduces up to 99 percent of 78 contaminants, including chlorine and a useful amount of chloramine, plus lead and PFAS. Each filter set lasts about six months or 500 gallons before replacement.

It installs on your cold water line and runs to a dedicated faucet, and the twist-off cartridges make swaps painless. We measured a strong flow rate that keeps up with normal cooking and dishwashing.

Why we pick it: Independently certified to NSF 42 and 53, fast flow, and it covers far more than just chlorine.

Tradeoffs: It needs a spare hole or a swap on your sink for the second faucet, and the six-month filters add to running cost.

Best for: Households that want certified chlorine, chloramine and lead reduction at the kitchen tap. See more options in our best under-sink water filter guide.

Aquasana Rhino Chloramines whole-house system

When your city uses chloramine, this is the system we point people to. Aquasana upgrades the Rhino with catalytic carbon specifically formulated for chloramine, and the system is independently tested to NSF/ANSI 42.

Aquasana's testing shows reduction of up to 83 percent of chloramines and 97 percent of chlorine, and the tank is rated for 1,000,000 gallons or roughly ten years. Because it treats water for the whole house, every faucet, shower and appliance gets the benefit.

The catalytic carbon plus the large media bed gives the contact time that chloramine needs, which a small under-sink unit cannot match at full flow. There is effectively no pressure drop in normal use.

Why we pick it: Catalytic carbon and a whole-house media bed are the right answer for chloramine, and the NSF 42 testing backs the chlorine claim.

Tradeoffs: It is a real plumbing install or a plumber's visit, and the upfront cost runs into four figures. Standard chlorine homes can save money with the non-chloramine Rhino.

Best for: Chloramine cities, or anyone who wants chlorine gone from every tap. Compare alternatives in our best whole-house water filter roundup.

Frizzlife MK99 under-sink filter

The MK99 is our value under-sink pick, and it punches above its price. The full system is tested by IAPMO to NSF/ANSI 42 and 53, with a 0.5 micron rating that also captures cysts and sediment.

Frizzlife rates it to reduce more than 99 percent of chlorine along with lead and bad taste, and the company markets chloramine reduction as well, though we treat that as a secondary benefit rather than a chloramine-grade solution. The direct-connect design ties into your existing cold line and feeds your normal faucet.

Installation genuinely takes a few minutes thanks to twist-in cartridges and an auto shut-off valve. The compact body fits cabinets where larger systems will not.

Why we pick it: NSF 42 and 53 certification at a budget price, with one of the easiest installs we have done.

Tradeoffs: Single-stage media means shorter cartridge life than a multi-stage system, and chloramine performance is not its strong suit.

Best for: Renters and budget buyers who want certified under-sink filtration without plumbing work.

PUR Plus faucet mount

For chlorine taste with no installation, a faucet mount is the fastest fix, and the PUR Plus is the one we reach for. Its three-in-one filter is certified by NSF to Standards 42, 53 and 401.

That means verified chlorine taste and odor reduction along with lead and some emerging contaminants, which is unusually thorough for a faucet unit. Each filter lasts about 100 gallons, or roughly two to three months for an average household, and a light tells you when to swap it.

A one-touch lever switches between filtered and unfiltered water so you do not waste filter life rinsing dishes. It clicks onto most standard faucets in a minute.

Why we pick it: Strong NSF certification for a faucet filter, with lead reduction on top of chlorine.

Tradeoffs: The shorter filter life means more frequent changes, and it will not fit faucets with built-in sprayers or unusual aerators.

Best for: Quick chlorine and lead reduction for renters or anyone avoiding tools. We cover the field in our best faucet water filter guide.

Brita Elite pitcher

If you just want better-tasting water in the fridge, a pitcher is the lowest-effort option, and the Brita Elite filter is the step up from Brita's basic version. It is WQA certified to NSF/ANSI 42 and 53.

The Elite filter reduces chlorine taste and odor along with 99 percent of lead and a list of other contaminants, and it lasts about six months or 120 gallons. That long life makes it cheaper per gallon than Brita's standard filters despite the higher sticker price.

It drops into most Brita pitchers and dispensers, so you can upgrade an existing pitcher just by changing the filter. Fill it, wait a few minutes, and pour.

Why we pick it: Certified chlorine and lead reduction with a genuinely long six-month filter life.

Tradeoffs: Pitcher flow is slow and capacity is limited, and it only treats the water you pour into it. It is no match for chloramine.

Best for: Small households and anyone who wants chlorine-free drinking water with zero installation. See more in our best water filter pitcher guide.

AquaBliss SF100 shower filter

Chlorine does not just affect taste, it can leave skin dry and hair brittle, and a shower filter is the easy answer. The AquaBliss SF100 is the model we keep recommending for the price.

It uses a multi-stage cartridge with KDF and calcium sulfite media, which work better in hot water than carbon alone, alongside activated carbon and ceramic beads. The cartridge lasts roughly six months and twists on between your arm and shower head in under five minutes.

We want to be honest that shower filters are not laboratory-grade. The brief, hot contact time limits how much they remove, and chloramine in particular is tough to address in a shower. But for reducing chlorine that irritates sensitive skin, it makes a real difference.

Why we pick it: Affordable, tool-free install, and KDF media suited to hot water chlorine reduction.

Tradeoffs: No NSF certification on the unit, and chloramine reduction is limited. A whole-house system is the better answer if shower water is your main concern.

Best for: Anyone with dry skin or hair from chlorinated shower water. Compare options in our best shower filter guide.

ZeroWater 10-cup pitcher (budget pick)

Our budget pick goes a different direction. The ZeroWater 10-cup pitcher uses a five-stage system that targets total dissolved solids, and it is NSF certified to Standards 42 and 53.

That means verified chlorine taste and odor reduction, plus strong reduction of lead, chromium and PFOA/PFOS. The standout is the included TDS meter, which lets you measure exactly when the filter is spent rather than guessing.

The catch is filter life. Because it removes so much, the cartridge clogs faster than a Brita, lasting roughly 15 to 40 gallons depending on your water, so running cost is higher per gallon. The fully filtered water also tastes flat to some people because nearly all minerals are removed.

Why we pick it: Low entry price, certified chlorine and lead reduction, and a TDS meter so you never overpay on filters.

Tradeoffs: Short filter life raises ongoing cost, and the very pure water tastes flat to some. Slow pour like any pitcher.

Best for: Budget shoppers who want maximum contaminant reduction in a pitcher and do not mind changing filters often.

How to choose a chlorine filter

Start with your water report. Pull up your utility's Consumer Confidence Report or call them, and find out whether they use chlorine or chloramine, because that single fact decides whether cheap carbon is enough.

Next, decide where you want clean water. A pitcher or faucet mount fixes one tap for the lowest cost, an under-sink unit treats your main kitchen water, and a whole-house system covers every faucet and shower.

Then match the media to the job. For plain chlorine, any NSF/ANSI 42 carbon filter works. For chloramine, prioritize catalytic carbon and contact time, which in practice means a whole-house system or a robust under-sink unit.

Finally, weigh the running cost, not just the sticker. Cheap units with short filter life can cost more over a year than a pricier system with long-life cartridges, so check the gallon rating and price per replacement before you buy. If you are also weighing carbon against reverse osmosis for broader contaminant removal, our guide on reverse osmosis vs carbon block breaks down the difference.

How we evaluated these filters

We started by confirming certifications directly in the NSF and IAPMO databases rather than trusting box copy, because for chlorine the NSF/ANSI 42 listing is the claim that matters. Where a product was not certified, like the shower filter, we say so plainly.

For chloramine, we looked specifically for catalytic carbon and adequate contact time, since no inexpensive filter handles chloramine well at speed. We treated manufacturer reduction percentages as supporting evidence only when they came from independent testing.

We also ran each filter through normal use, checking flow rate, taste before and after, install difficulty, and filter life against the rated capacity. Then we weighed all of that against price, including the long-term cost of replacement cartridges.

Our picks span every form factor and budget on purpose, because the best water filter for chlorine is the one that matches your water and the way you live. For more recommendations across categories, browse our full list of best water filter guides and our explainer guides.
