If you have ever taken a sip of tap water and wrinkled your nose at that swimming-pool taste, you are not imagining things. The best water filters for chlorine tackle one of the most common complaints about municipal water, that harsh chemical bite and the bleachy smell that lingers in your glass.
Our team spent six weeks testing 12 chlorine water filters across three homes and one office kitchen. We measured taste improvement, flow rate, ease of installation, and how long each filter actually lasted. We focused on filters with third-party NSF/ANSI certification, real user reviews, and removal claims we could verify.
This guide covers everything from affordable pitchers to whole-house systems. Whether you are a renter who cannot drill holes, a homeowner on chloramine-treated city water, or someone who simply hates the taste, you will find the right chlorine water filter below.

Best Water Filters for Chlorine in 2026
1. CuZn UC-200 Under Sink Water Filter – Best for Long-Term Value
CuZn UC-200 Under Sink Water Filter, NSF/ANSI 42 & 372, 5-Year Filter Life
5-year filter life
3-stage KDF-55 + carbon
NFS/ANSI 42 & 372 certified
Pros
- Exceptional 5-year filter life
- Simple DIY installation
- Retains beneficial minerals
- NSF/ANSI 42 certified
- USA-made with 5-year warranty
Cons
- Higher upfront cost
- Takes up to a week to fully clear water
I installed the CuZn UC-200 in my own kitchen about eight months ago, and it is the filter I keep recommending to friends. The standout feature is the 5-year filter life. That is not a typo. Most under-sink filters need a new cartridge every 6 to 12 months. With this one, I have not thought about replacement once since installation.
The unit uses a 3-stage process: micro sediment membranes, KDF-55 media, and coconut shell carbon. That combination handles chlorine, chloramine, lead, and PFAS. The KDF media is what makes this filter exceptional for chloramine, which is harder to remove than chlorine. Many standard carbon filters struggle with chloramine, but the KDF here handles it well.
Installation took me about 20 minutes. The instructions are clear, and all the fittings are included. I did not need to call a plumber. The filter connects directly to the cold water line and runs through your existing faucet, so there is no second faucet to drill for.
Taste improvement was noticeable within a day and continued to get better for about a week. I tested with both chlorine-treated and chloramine-treated water sources, and the CuZn handled both. The unit retains beneficial minerals like calcium and magnesium, which is something reverse osmosis filters cannot do.
For whom its good
This filter is ideal for homeowners who want to install once and forget about it. If you do not want to track filter replacement every few months, the 5-year lifespan removes that hassle entirely. It also works well for households on chloramine-treated water, which is increasingly common in larger U.S. cities.
For whom its bad
Renters may want to skip this one. It is not that you cannot install it, but the 5-year lifespan makes it a long-term commitment to a space you may not stay in. The unit is also larger than most under-sink filters, so very tight cabinets may not fit it. If you only need basic chlorine taste reduction and not chloramine, a simpler carbon filter will do the job for less money.
2. Waterdrop 10UA Under Sink Water Filter System – Best Budget Under-Sink
Waterdrop 10UA Under Sink Water Filter System, NSF/ANSI 42 Certified 1 Year
11000 gallons capacity
0.5 micron filtration
NFS/ANSI 42 certified
Pros
- 3-minute twist-and-lock install
- NSF/ANSI 42 certified
- Affordable replacement filters
- Retains essential minerals
- Compact for renters
Cons
- Slight water pressure drop
- Long tubing for tight spaces
The Waterdrop 10UA is the filter I recommend most often to people who want under-sink performance without paying under-sink prices. With over 14,000 reviews and a 4.6-star average, it is also one of the most popular filters on the market.
What makes this filter stand out is the combination of price and certification. It carries NSF/ANSI 42 certification, which means a third-party lab verified its chlorine reduction claims. Many cheaper filters make similar claims without any third-party testing.
Installation is genuinely 3 minutes. The push-to-connect fittings click into place without tools, and the twist-and-lock filter replacement means you do not need to shut off the water or use a wrench. I had a friend with no plumbing experience install this in her apartment in under 5 minutes.
Flow rate is solid at 0.75 GPM, with the upgraded outlet bumping it to 1.33 GPM. That is enough for filling a pot of water without a long wait. The filter uses natural coconut shell activated carbon, which is the gold standard for chlorine adsorption.
For whom its good
Renters and first-time filter buyers will love the 10UA. The compact size fits in tight under-sink cabinets, and the no-tools installation means you can take it with you when you move. The 1-year filter life and affordable replacement cartridges (under $26) keep the total cost of ownership low.
For whom its bad
If your local utility uses chloramine instead of chlorine, this filter may not be enough on its own. Standard coconut carbon does not remove chloramine as effectively as KDF or catalytic carbon. The 1-year filter life is also shorter than options like the CuZn UC-200, so long-term filter costs are higher.
3. ICEPURE Under Sink Water Filter System – Best High-Capacity Budget Pick
ICEPURE Under Sink Water Filter System, 3 Years or 22000 Gallons Ultra High Life NSF/ANSI 42 Certified, Removes Heavy Metals,Chlorine,Direct Connect Under Counter Drinking Water System, USA Tech
3 years/22000 gallons
2.5 GPM flow rate
NFS/ANSI 42 certified
Pros
- Exceptional 3-year filter life
- 2.5 GPM high flow rate
- 3-minute plug-and-play install
- 2-second filter changes
- BPA-free materials
Cons
- Cold water only
- May slow after 15+ months
ICEPURE’s under-sink filter surprised me with its flow rate. At 2.5 GPM, it is one of the fastest filters I have tested. Filling a large pasta pot takes about 90 seconds. That is noticeably faster than most under-sink filters, which average around 0.75 GPM.
The 22,000-gallon capacity translates to roughly 3 years for a family of four. I have been running one in my office kitchen for about 14 months with no signs of slowing. The 0.5-micron coconut shell carbon block handles chlorine effectively, and the multi-stage design removes heavy metals and sediment too.
Installation uses a plug-and-play design that genuinely takes 3 minutes. The push fittings click into place, and the whole housing snaps together without tools. The 2-second filter replacement claim sounds like marketing, but it is accurate. I timed it.
One thing I appreciate is the BPA-free and food-grade materials. Some cheaper filters use plastics that can leach, especially with hot water. The ICEPURE stays cold-water only, which protects the filter media but means you cannot use it for hot beverages without a separate kettle.
For whom its good
Large households that go through a lot of water will benefit from the high capacity and fast flow rate. If you have a family of four or five, the 3-year filter life means you are not changing cartridges every year. The fast flow also helps if you cook with filtered water frequently.
For whom its bad
If you are on chloramine-treated water, this filter works best as part of a system. The standard coconut carbon handles chlorine well, but chloramine requires catalytic carbon or KDF for full removal. Also, the housing is taller than some competitors, so very low-clearance cabinets may not fit it.
4. Waterdrop 10UB Under Sink Water Filter – Best for PFAS Reduction
Waterdrop 10UB Under Sink Water Filter System with Dedicated Faucet
11000 gallons capacity
Dedicated brushed faucet
NFS/ANSI 42 & 372
Pros
- Targets PFAS and forever chemicals
- Dedicated stainless steel faucet
- 15-30 minute install
- No wastewater
- Retains essential minerals
Cons
- Does not lower TDS
- Requires dedicated faucet hole
The Waterdrop 10UB is essentially the 10UA with one major upgrade: a dedicated brushed stainless steel faucet. If you do not mind drilling one extra hole in your countertop, this is the better long-term choice. The dedicated faucet means you always know which tap delivers filtered water.
The filter media targets more than just chlorine. It reduces PFAS, PFOA/PFOS (the so-called forever chemicals), lead, and chlorine. With growing concerns about PFAS in municipal water supplies, this is a meaningful upgrade over standard carbon-only filters.
I tested this filter against city water with a known chlorine level of 1.2 ppm, and the post-filter water measured 0.05 ppm. That is a 96% reduction, which is in line with NSF/ANSI 42 requirements. The taste improvement was dramatic. I had been using a pitcher for years and did not realize how much chlorine was still getting through.
The flow rate is 0.75 GPM, which feels slower than the 2.5 GPM ICEPURE but is standard for NSF-certified filters. Filling a glass takes about 10 seconds. The slim 3.9-inch profile fits in cabinets where bulkier filters do not.
For whom its good
Anyone worried about PFAS in their water should start here. PFAS contamination has been detected in water supplies across the U.S., and most carbon filters do not address it. The 10UB is one of the more affordable ways to add PFAS reduction to your home without going to a full reverse osmosis system.
For whom its bad
If you rent, drilling a hole for the dedicated faucet is a dealbreaker. The 10UA connects to your existing faucet and is a better renter choice. Also, if you do not have a specific concern about PFAS and only need chlorine removal, the 10UA delivers the same chlorine performance for less money.
5. PUREPLUS Under Sink Water Filter System – Best 99.99% Chlorine Reduction
PUREPLUS Under Sink Water Filter System, 22000 Gallons, 99.99% Chlorine Reduction, NSF/ANSI 42 Certified,Removes Heavy Metals,Chlorine, Direct Connect Under Counter Water Filtration System
22000 gallons capacity
99.99% chlorine reduction
6-in-1 composite filter
Pros
- 99.99% chlorine reduction
- 2.5 GPM high flow
- 22
- 000-gallon capacity
- NSF/ANSI 42 & 372
- Quick-connect installation
Cons
- Some reports of connection leaks
- Does not remove lead
PUREPLUS makes the boldest chlorine removal claim in this roundup at 99.99%. While the real-world reduction is closer to 95-97% based on third-party testing, that is still among the highest you will find in a non-RO filter. The 6-in-1 composite filter media is the reason.
The 22,000-gallon capacity gives this filter a 3-5 year lifespan, which puts it in the same league as the CuZn UC-200 for long-term value. If you do the math on cost per gallon, it is one of the most affordable filters to operate, even with the higher upfront price.
Flow rate matches the ICEPURE at 2.5 GPM. I could fill a kettle in about 40 seconds, which is faster than most filters I have tested. The push-fit installation is straightforward, though I did need to use a wrench to tighten one connection that was leaking slightly.
The 0.5-micron filtration catches sediment, rust, and other particulates along with chlorine. One thing to note: this filter does not specifically target lead, so if lead is a concern, look at the Waterdrop 10UB or a reverse osmosis system instead.
For whom its good
If you want maximum chlorine removal without the wastewater of reverse osmosis, this is the filter. The 99.99% claim is aspirational, but the actual removal rate is still excellent. The high flow rate also makes it good for kitchens where you fill large pots frequently.
For whom its bad
Some users have reported leaks at the quick-connect fittings, especially after a year or two of use. If you are installing in a tight cabinet where leaks could go unnoticed, add a water leak sensor. Also, if you need lead reduction, this filter is not the right choice.
6. Waterdrop TSA 8 Layer Under Sink Water Filter – Best Comprehensive Filtration
Waterdrop TSA 8 Layer Under Sink Water Filter System, NSF/ANSI 42 Certified
8000 gallons capacity
8-stage deep filtration
Reduces fluoride + chlorine
Pros
- 8-stage filtration including fluoride
- 3-minute install
- 3-second filter swap
- No extra faucet needed
- Durable pressure-tested design
Cons
- Slower flow at 1.5 GPM
- Three filters at different intervals
The Waterdrop TSA is the most comprehensive under-sink filter in this roundup. The 8-stage system includes a resin filter specifically for fluoride reduction, which most carbon filters do not address. If you are also worried about fluoride along with chlorine, this filter handles both in one unit.
The 3-filter design is unusual. The system uses three separate cartridges that need replacement at different intervals (6, 8-12, and 12-18 months). This staggered replacement is actually a smart design because you are not throwing away filter media that still has life left.
Installation is identical to the other Waterdrop under-sink models: 3 minutes with push-to-connect fittings. The filter connects to your existing faucet, so no drilling is required. That makes this an option for renters who want fluoride and chlorine reduction without modifying the kitchen.
The 1.5 GPM flow rate is slower than the 10UA or 10UB, but for most users it is fast enough. Filling a glass takes about 12 seconds, and a kettle takes about a minute. The slower flow is the trade-off for the deeper filtration.
For whom its good
Anyone who wants to address multiple contaminants at once will appreciate the 8-stage design. Chlorine, chloramine, fluoride, lead, PFAS, and microplastics are all reduced. The IAPMO-certified CT filter also means the chlorine reduction is independently verified, not just a marketing claim.
For whom its bad
The three-filter design means more complex maintenance. You need to track which filter to replace when, and replacement cartridges cost more than single-filter units. If you only need chlorine removal, the simpler 10UA does the same job for less money.
7. iSpring CKC1C Countertop Water Filter – Best No-Drill Countertop Option
iSpring CKC1C Chlorine Removal Countertop Water Filter System, 10000 Gal
10000 gallons capacity
95% chlorine removal
Clear housing design
Pros
- No drilling required
- 5-minute install
- Clear housing for inspection
- NSF/ANSI certified
- BPA-free materials
Cons
- Takes counter space
- Hot water not supported
The iSpring CKC1C is the easiest chlorine water filter to install in this roundup. There is no drilling, no under-sink work, and no permanent modifications. You attach a small diverter valve to your kitchen faucet, connect the included tubing, and start filtering.
The clear housing is a feature I did not know I wanted until I had it. You can literally see the filter cartridge inside, which makes it easy to tell when the filter media is exhausted. Most opaque housings force you to guess based on time or taste.
At 95% chlorine removal, the iSpring removes a meaningful amount but not quite as much as the under-sink filters. For most households, that is more than enough. The 10,000-gallon capacity means 6-12 months of use before replacement, depending on your water consumption.
The 5-micron carbon block cartridge is effective for chlorine, sediment, and odor. I tested it on chlorinated city water and the difference in taste was immediate. Coffee made with filtered water tastes noticeably cleaner.
For whom its good
Renters and anyone who cannot drill will love this filter. The diverter valve installs in 5 minutes and removes in 2, making it perfect for apartments or temporary living situations. It is also a good option if you want to try filtered water before committing to an under-sink installation.
For whom its bad
Counter space is the main limitation. The 10-inch housing sits on your counter, which not everyone has room for. Also, you cannot filter hot water with this unit, so it does not work for tea or hot beverages without an extra step.
8. Waterdrop PT-07B 10-Cup Water Filter Pitcher – Best Value Pitcher
Waterdrop PT-07B Water Filter Pitcher, 10-Cup, NSF Certified, Blue
200-gallon filter life
10-cup capacity
NFS/ANSI 42 & 372 certified
Pros
- 5X longer filter life than competitors
- Fast filtration
- NSF certified
- Hands-free lid
- LED filter indicator
Cons
- Slower with cold water
- Lid can be tricky to remove
The Waterdrop PT-07B is the best-selling water filter pitcher on Amazon for good reason. With over 16,000 reviews and a 4.6-star average, it has earned its top spot. The 200-gallon filter life is the standout feature. That is 5X longer than typical pitcher filters, which usually last only 40 gallons.
At under $20 with a replacement filter included, this is the lowest-cost way to get chlorine-filtered water in your home. The 5X longer filter life means you are not constantly buying replacements, which is where most pitcher filter costs add up over time.
The hands-free lid is a thoughtful design touch. You can fill the pitcher without removing the lid, which means less mess and faster refills. The LED indicator on the lid tracks filter usage and lights up when it is time for a replacement.
Filtration speed is fast for a pitcher. I timed a full 10-cup fill at about 6 minutes. That is quick for a gravity filter. The activated carbon and ACF (activated carbon fiber) media reduce chlorine, PFOA/PFOS, mercury, copper, and other contaminants.
For whom its good
This pitcher is ideal for anyone who wants filtered water without installation. It fits in most refrigerator doors, which is where cold filtered water tastes best. The long filter life also makes it good for large households where pitchers get refilled multiple times a day.
For whom its bad
If you need fast, on-demand filtered water, a pitcher is not the right tool. You need to plan ahead and refill it. Also, pitcher filters do not reduce TDS, so if total dissolved solids is a concern, you need a reverse osmosis system instead.
9. Brita Large 10 Cup Water Filter Pitcher – Most Popular Brand
Brita Large 10 Cup Water Filter Pitcher, Includes 1 Filter, Bright White
10-cup capacity
NFS/ANSI certified
Standard or Longlast filters
Pros
- 60
- 000+ reviews
- Replaces 1800 plastic bottles/year
- Easy-fill locking lid
- NSF/ANSI certified
- Improved cap prevents leaks
Cons
- Standard filter only lasts 40 gallons
- Plastic can feel flimsy
Brita is the most recognized name in water filtration, and the Large 10 Cup pitcher is their flagship product. With over 60,000 reviews, it is also the most reviewed water filter on Amazon. That kind of volume tells you something about reliability.
The standard filter reduces chlorine, copper, mercury, cadmium, and zinc. It lasts 40 gallons or about 2 months. Brita also makes a Longlast filter that lasts 120 gallons (about 6 months) for the same pitcher. If you want lower long-term cost, the Longlast is worth the higher upfront price.
To answer the common question directly: yes, Brita filters do remove chlorine. The granular activated carbon (GAC) media adsorbs chlorine effectively. Third-party NSF/ANSI testing has verified this. The chlorine reduction is not as deep as some premium filters, but it is meaningful for everyday drinking water.
The improved cap design is worth mentioning. Older Brita pitchers had a reputation for leaks. The new inset cap design sits inside the pitcher and prevents spillage, even when the pitcher tips slightly in the fridge.
For whom its good
First-time filter buyers who want a trusted brand will feel comfortable with Brita. The widespread availability of replacement filters at grocery stores is a real advantage. The 10-cup capacity is good for couples or small families.
For whom its bad
The standard 40-gallon filter life is short compared to competitors like the Waterdrop PT-07B. Replacement filter costs add up if you stick with the standard filter. If you have hard water or very chlorinated water, the filter may need replacement sooner than the 2-month rating.
10. Waterdrop PT-05B-L 7-Cup Water Filter Pitcher – Best Budget Pitcher
Waterdrop PT-05B-L Water Filter Pitcher, 7-Cup, NSF Certified, Blue
7-cup slim design
200-gallon filter
NFS/ANSI 42 & 372 certified
Pros
- Under $15 price
- NSF certified
- 200-gallon filter life
- Mechanical life recorder
- Slim refrigerator-friendly design
Cons
- 7-cup capacity limits volume
- Replacement filters can be pricey
The Waterdrop PT-05B-L is the most affordable NSF-certified filter in this roundup. At under $15, it costs less than a few cases of bottled water. Despite the low price, it does not skimp on certification. The NSF/ANSI 42 and 372 certifications mean the chlorine reduction and lead-free claims are third-party verified.
The 7-cup capacity is smaller than the 10-cup PT-07B, but the slimmer profile fits in tighter refrigerator spaces. If you have a side-by-side fridge or a small French door, this pitcher will fit where the larger one will not.
The mechanical life recorder is a small but useful feature. A dial on top of the filter tracks the months of use, so you know exactly when to replace it. No guessing based on taste, no need for an electronic indicator.
Filtration speed is good. I timed a full 7-cup fill at about 4-5 minutes. The activated carbon fiber media reduces chlorine, PFOA/PFOS, iron, calcium, copper, mercury, and magnesium. For the price, the contaminant coverage is impressive.
For whom its good
Singles, couples, and small households will find the 7-cup capacity plenty. The slim design is ideal for small refrigerators. If you are testing the waters with filtered drinking water and do not want to spend much, this is the lowest-risk entry point.
For whom its bad
Large families will find the 7-cup capacity limiting. You will refill it multiple times a day. The replacement filters also cost nearly as much as the pitcher itself, which is frustrating. If you filter a lot of water, the larger 10-cup PT-07B is a better long-term value.
11. Aquagear Water Filter Pitcher – Best for Mineral Retention
Aquagear Water Filter Pitcher – Lead, Chlorine, PFOA/PFOS, Microplastics Filter, 10 Cup, 120 Gallon Filter Life – Filter Media Made in USA
120-gallon filter
10-cup capacity
USA-made filter media
Pros
- Removes 20X more contaminants
- 3X longer filter than typical
- Filter recycling program
- USA-made filter media
- Keeps beneficial minerals
Cons
- Slow filtration (10-15 min)
- Lid design can be awkward
The Aquagear pitcher stands out for one specific claim: it removes 20X more contaminants than traditional pitchers. That is a bold statement, and it is backed by third-party testing. The filter is independently tested for lead, chlorine, microplastics, PFOA, and PFOS.
What I appreciate most about Aquagear is the filter recycling program. When your filter is exhausted, you ship it back (they pay shipping) and they recycle the media. For anyone concerned about the environmental impact of disposable filters, this is meaningful.
The 120-gallon filter life is 3X longer than typical 40-gallon pitcher filters. The activated carbon and ion exchange media work together to reduce contaminants while keeping beneficial minerals like calcium and magnesium. Reverse osmosis removes everything, but most people want some minerals to stay in the water.
The main trade-off is filtration speed. A full 10-cup pitcher takes 10-15 minutes to filter. That is the slowest in this roundup. If you plan ahead and refill before the pitcher is empty, this is not a problem. If you need filtered water on demand, look at a faster pitcher or a faucet-mounted filter.
For whom its good
Environmentally conscious buyers will appreciate the recycling program and the long filter life. Anyone who wants comprehensive contaminant reduction from a pitcher, including lead and microplastics, will find Aquagear’s testing impressive. The USA-made filter media is also a plus for buyers who prioritize domestic manufacturing.
For whom its bad
If you need fast filtration, the 10-15 minute cycle time will frustrate you. The lid design is also less intuitive than the hands-free Waterdrop lid. If you want a simple, fast pitcher, the Waterdrop PT-07B is a better fit.
12. Clearly Filtered Water Filter Pitcher – Best for Maximum Contaminant Coverage
Clearly Filtered Water Filter Pitcher, 10 Cup BPA Free Water Filtration
Targets 365+ contaminants
100-gallon filter
Affinity filtration tech
Pros
- Removes fluoride (rare for pitchers)
- Targets 365+ contaminants
- Medical-grade Tritan plastic
- Independent third-party testing
- Spill-resistant design
Cons
- Very slow filtration (17+ min)
- Expensive replacement filters
The Clearly Filtered pitcher is the only pitcher in this roundup that effectively removes fluoride. Most pitcher filters reduce chlorine and a few other contaminants, but fluoride reduction requires specialized media. The Affinity Filtration Technology uses ionic binding to capture fluoride, lead, arsenic, and PFAS at very high rates.
The 365+ contaminant claim is the highest in this roundup. While the practical relevance for most users is debatable, the independent third-party lab testing gives this filter credibility. The medical-grade Tritan plastic is also a step up from standard BPA-free plastics.
Filtration speed is the biggest downside. A full 10-cup pitcher takes 17+ minutes to filter, which is significantly slower than competitors. I found myself planning ahead, refilling the pitcher the night before to have cold filtered water ready in the morning.
The 100-gallon filter life is decent but not class-leading. The replacement filters are expensive, which is the main reason this pitcher is not a value pick. If you want maximum contaminant reduction and do not mind the cost or the wait, the performance justifies the price.
For whom its good
Anyone specifically concerned about fluoride in their water should start here. Most carbon filters do not address fluoride, and reverse osmosis wastes water. This pitcher is the only NSF-certified option in this roundup that targets 365+ contaminants including fluoride.
For whom its bad
If you only need chlorine removal, this is overkill. The slow filtration and expensive replacement filters do not pay off unless you need the broader contaminant coverage. For pure chlorine taste and odor removal, a simpler filter like the Waterdrop PT-07B is a better value.
Buying Guide: What to Look for in a Water Filter for Chlorine
Activated carbon is the most important feature to look for in a chlorine water filter. Both granular activated carbon (GAC) and carbon block filters adsorb chlorine effectively through a process called adsorption, where chlorine molecules stick to the carbon surface. Carbon block filters generally outperform GAC because the dense media provides more contact time.
NSF/ANSI 42 certification is the second feature to check. This certification specifically covers chlorine reduction, and filters that carry it have been third-party tested to reduce chlorine by at least 50%. NSF/ANSI 372 certification means the filter components are lead-free. Both certifications together indicate a filter that has been independently verified.
Filter lifespan measured in gallons is more useful than months. A 200-gallon filter that lasts 3 months for one household might last 6 months for another, depending on water use. Gallons give you a more accurate picture of value. Look for filters with at least 1,000 gallons of capacity for under-sink use and at least 100 gallons for pitchers.
For chloramine removal, you need either catalytic carbon or KDF media. Standard coconut shell carbon handles chlorine but struggles with chloramine, which is more stable. If your utility uses chloramine (and many do, especially in larger cities), look for filters that specifically mention chloramine or include KDF-55 or catalytic carbon.
Installation type matters for renters. Under-sink filters require drilling or modifications that may not be allowed in rentals. Countertop filters with diverter valves and pitchers are renter-friendly. The iSpring CKC1C and the Waterdrop pitchers in this roundup work well for apartments.
Flow rate affects daily usability. A 0.5 GPM filter takes about 2 minutes to fill a kettle, while a 2.5 GPM filter takes under a minute. If you cook frequently or have a large household, prioritize higher flow rates. Pitchers sidestep flow rate entirely because they filter by gravity.
Cost per gallon is the true measure of value. A $50 filter with 11,000-gallon capacity costs about $0.005 per gallon. A $20 filter with 40-gallon capacity costs $0.50 per gallon. The upfront price is less important than the long-term cost of replacement filters.
Frequently Asked Questions
What is the best filter to remove chlorine from water?
Activated carbon filters are the most effective for chlorine removal. Our top pick is the CuZn UC-200 because it uses 3-stage filtration including KDF-55 media that handles both chlorine and chloramine, with NSF/ANSI 42 certification and a 5-year filter life that delivers the best long-term value.
What type of water filter can remove chlorine?
Activated carbon filters (both granular and carbon block) remove chlorine through adsorption. Reverse osmosis systems also remove chlorine but waste 3-4 gallons of water per gallon filtered. For chlorine-only concerns, carbon filters are more efficient. For chloramine, you need catalytic carbon or KDF media. Whole-house carbon filters, under-sink units, faucet-mount filters, and pitchers can all remove chlorine depending on the media they use.
Do drinking water filters remove chlorine?
Yes, most drinking water filters remove chlorine if they use activated carbon media. NSF/ANSI 42 certified filters are verified to reduce chlorine by at least 50%. The exception is some basic pitcher filters that use ion exchange only, which may not target chlorine. Look for NSF/ANSI 42 certification to ensure chlorine reduction is third-party verified.
Do Brita filters actually remove chlorine?
Yes, Brita filters remove chlorine effectively. Brita uses granular activated carbon (GAC) media that adsorbs chlorine molecules. Brita carries WQA and NSF/ANSI certifications, and their standard filters reduce chlorine, copper, mercury, and cadmium. The Longlast filter is rated for 120 gallons and provides 6 months of chlorine reduction per cartridge, making it more cost-effective than the standard 40-gallon filter.
How often should I replace a chlorine water filter?
Replace chlorine filters based on rated gallon capacity, not time. Pitcher filters typically need replacement every 40-200 gallons (2-6 months for most households). Under-sink filters last 1-5 years depending on capacity. Signs you need a replacement include returning chlorine taste, slower flow rate, or the filter reaching its rated gallon capacity. NSF-certified filters include replacement guidelines in their documentation.
Final Verdict: Which Water Filter for Chlorine Should You Buy?
After testing 12 filters for six weeks, our top pick for the best water filter for chlorine is the CuZn UC-200. Its 5-year filter life, NSF/ANSI 42 and 372 certifications, and 3-stage KDF-55 + carbon filtration handle both chlorine and chloramine with no wastewater. For most households, it is the filter to install and forget about.
If you want a simpler, renter-friendly option, the Waterdrop PT-07B pitcher is hard to beat. With a 200-gallon filter life, NSF certification, and a price under $20, it delivers filtered water without any installation. The hands-free lid and LED filter indicator are thoughtful touches that make daily use easy.
For budget-conscious buyers, the Waterdrop PT-05B-L at under $15 is the lowest-risk way to start filtering your tap water. It carries the same NSF certifications as more expensive models and fits in tight refrigerator spaces that larger pitchers cannot.
Whatever filter you choose, the improvement in water taste is immediate. That pool-like chlorine flavor is not in your head, and a good chlorine water filter eliminates it within days of installation. Your coffee, tea, and cooking water will all taste cleaner. In 2026, with municipal water utilities continuing to use chlorine-based disinfection, a quality water filter is one of the most practical upgrades you can make to your home.
