Chlorine is the most common contaminant people want to remove from their water — and ironically, it’s there on purpose. Municipal water utilities add chlorine (or chloramine, a chlorine-ammonia compound) to kill bacteria and viruses during treatment and distribution. It’s effective, cheap, and has prevented countless waterborne disease outbreaks since the early 1900s. But by the time that chlorinated water reaches your tap, the disinfection job is done, and what’s left is a chemical that makes your water taste like a swimming pool, dries out your skin and hair in the shower, and produces disinfection byproducts (DBPs) like trihalomethanes that the EPA regulates as potential carcinogens.
The good news: chlorine is one of the easiest contaminants to remove. Activated carbon — the same material in most water filters — adsorbs chlorine extremely effectively. Even a basic $20 pitcher filter removes 90-99% of free chlorine. The challenge isn’t removing chlorine; it’s choosing the right system for your specific situation. Do you want chlorine-free water at one tap or every tap? Do you also need to remove chloramine (which requires catalytic carbon, not standard activated carbon)? And do you want to address other contaminants while you’re at it?
One critical distinction before we start: chlorine and chloramine are different chemicals that require different filtration approaches. Standard activated carbon removes free chlorine quickly and effectively. Chloramine is more stable and requires either catalytic carbon (a specially treated form of activated carbon) or a longer contact time with standard carbon. About 30% of US water utilities now use chloramine instead of chlorine — check your annual water quality report (CCR) to find out which your utility uses. If you’re on chloramine, make sure your filter is specifically rated for chloramine removal, not just chlorine.
SpringWell CF1 Whole House Water Filter System<br />
Best Water Filters for Chlorine Removal — 7 Systems From Budget to Whole-House
1. SpringWell CF1 Whole House Water Filter — Best Overall for Chlorine
If you want chlorine removed from every drop of water in your home — not just the kitchen tap — the SpringWell CF1 is the system to buy. It installs at your main water line and treats all water entering your house: kitchen, bathrooms, showers, laundry, even outdoor hose bibs. The 4-stage filtration system uses catalytic coconut shell carbon (which handles both chlorine AND chloramine), KDF media (which removes heavy metals and inhibits bacterial growth), and a sediment pre-filter. SpringWell claims 99.6% chlorine removal and 99% chloramine removal — among the highest rates in the whole-house category.
The CF1 is rated for 1,000,000 gallons — approximately 10 years for a typical household of 2-4 people. The flow rate is 9 GPM for the CF1 model (designed for 1-3 bathroom homes), with larger CF4 and CF+ models available for bigger homes at 12-20 GPM. The system also removes VOCs, PFAS, pesticides, herbicides, and haloacetic acids (chlorine disinfection byproducts). It does NOT remove fluoride, TDS, or dissolved minerals — it’s a targeted chemical contaminant filter, not a total purification system.
The CF1 retails for $800-$950 from SpringWell’s direct website. Annual maintenance cost is minimal: the sediment pre-filter needs replacement every 6-9 months ($15-$25), and the main carbon/KDF media lasts the full 10-year rated life. That works out to roughly $80-$95 per year over the system’s lifetime — less than most under-sink filters cost annually. SpringWell offers a lifetime warranty on the tank and valve, plus a 6-month money-back guarantee. Professional installation runs $200-$500 depending on your plumbing configuration; handy homeowners can DIY in 2-4 hours.
The whole-house approach has a benefit that point-of-use filters can’t match: chlorine-free shower and bath water. Chlorine exposure through skin absorption and inhalation of steam during hot showers can be significant — some studies suggest you absorb more chlorine in a 10-minute shower than from drinking 8 glasses of chlorinated water. If you’ve noticed dry skin, brittle hair, or irritated eyes, whole-house dechlorination often provides noticeable improvement within weeks. The CF1’s catalytic carbon also handles chloramine, which standard shower filters and many whole-house systems can’t effectively remove.
2. Aquasana EQ-1000 Rhino Whole House Filter — Best for Long-Term Value
The Aquasana Rhino EQ-1000 is the most established whole-house water filter on the market, with over a decade of production history and hundreds of thousands of installations. Like the SpringWell, it treats all water entering your home. The filtration system uses a combination of activated carbon, catalytic carbon, and KDF-55 media in an upflow design that maximizes contact time and filter life. Aquasana claims up to 97% chlorine removal — slightly lower than SpringWell’s 99.6% claim, but still highly effective for practical purposes.
The EQ-1000 is rated for 1,000,000 gallons or 10 years, whichever comes first. Flow rate is 7 GPM — adequate for most 1-3 bathroom homes but lower than the SpringWell’s 9 GPM. The system also reduces VOCs, pesticides, herbicides, and industrial solvents. Aquasana offers the EQ-1000 in several configurations: standalone filter ($700-$800), with salt-free water conditioner ($1,200-$1,500), and with UV purifier ($1,500-$2,500). The standalone filter is what you need for chlorine removal; the add-ons address hard water and biological contaminants respectively.
The standalone EQ-1000 retails for $700-$800 — slightly less than the SpringWell CF1. Annual maintenance includes a 20-inch pre-filter replacement every 2-3 months ($15-$20 each) and a post-filter replacement every 12 months ($50-$70). Total annual maintenance runs approximately $120-$150 — higher than the SpringWell due to more frequent pre-filter changes. Aquasana offers a 10-year warranty on the tank and a 90-day satisfaction guarantee. Installation is similar to the SpringWell: professional recommended, DIY possible for experienced homeowners.
The Aquasana’s upflow design is a genuine engineering advantage. Water enters at the bottom of the tank and flows upward through the media, which creates a more even distribution and prevents channeling (where water finds the path of least resistance and bypasses some of the filter media). This design extends effective filter life and maintains more consistent performance over the 10-year rated period. The trade-off is the lower 7 GPM flow rate and higher annual maintenance cost compared to the SpringWell.
3. Frizzlife SK99-NEW Under-Sink Filter — Best Under-Sink for Chlorine
For chlorine removal at a single tap, the Frizzlife SK99-NEW delivers excellent performance at a fraction of the whole-house system cost. The 3-stage filtration system uses a 0.5-micron carbon block as its primary media — one of the tightest carbon block ratings available in a consumer filter. At 0.5 microns, the carbon block provides extensive surface area for chlorine adsorption, resulting in 99%+ chlorine removal according to its NSF/ANSI 42 and 53 certifications. The system also reduces lead, chloramine, fluoride, heavy metals, and VOCs.
The SK99-NEW’s direct-connect design is its biggest practical advantage for chlorine removal. It connects to your existing kitchen faucet’s cold water supply — no dedicated faucet, no countertop drilling, no separate dispenser. Every time you turn on the cold water, it’s filtered. This means your cooking water, coffee water, ice maker water (if connected), and drinking water all benefit from chlorine removal without any behavioral change. You don’t have to remember to use a separate faucet or fill a pitcher.
At $90-$100 on Amazon, the SK99-NEW costs roughly 10% of a whole-house system. Replacement filters cost $30-$35 and last 6-12 months (1,600 gallons), putting annual filter cost at $35-$70. Installation takes 10 minutes with no tools. The twist-and-lock filter replacement takes under 30 seconds. For renters, apartment dwellers, or anyone who primarily wants chlorine-free water at the kitchen tap, the SK99-NEW is the most practical and economical choice.
The limitation is scope: the SK99-NEW only filters cold water at one faucet. Your shower, bath, and other taps still deliver chlorinated water. If shower chlorine exposure is a concern, you’d need to add a separate shower filter ($20-$40) or invest in a whole-house system. The SK99-NEW also reduces flow rate slightly — from the standard 2.2 GPM to approximately 1.5-2.0 GPM — which is barely noticeable for filling glasses but slightly slower for filling large pots.
4. PUR PLUS Faucet Mount FM-3700B — Best Faucet-Mount for Chlorine
The PUR PLUS FM-3700B is the most comprehensively certified faucet-mount filter for chlorine removal. Its 3-stage Mineral Core filtration system uses activated carbon and ion exchange media to remove 99% of chlorine taste and odor — certified to NSF/ANSI 42. But the FM-3700B goes well beyond basic chlorine removal: it’s also NSF/WQA certified to reduce 70+ contaminants including lead (99%), mercury, pesticides, pharmaceuticals, and microplastics under NSF/ANSI 53 and 401 standards.
The faucet-mount design provides on-demand filtered water with a simple lever switch. Flip the lever to “filtered” for drinking and cooking water; flip it back to “unfiltered” for dishes and hand washing. This selective filtering extends filter life by only processing water you actually drink. Each filter (RF-9999) is rated for 100 gallons or approximately 2-3 months. The complete system with one filter retails for $25-$35 — the lowest entry cost on this list for certified chlorine removal.
Replacement filters cost $12-$18 each, putting annual filter cost at $48-$108 depending on usage. Installation takes 5 minutes: remove your faucet aerator, attach the PUR mount, done. No tools, no plumbing modifications, no under-sink access needed. The FM-3700B is compatible with most standard faucets but does NOT fit pull-out, handheld, or sensor faucets — check compatibility before purchasing.
The 100-gallon filter life is the main drawback. For a family of four, you’ll replace filters every 6-8 weeks. The per-gallon cost is higher than under-sink or whole-house systems. But for simplicity, affordability, and breadth of certified contaminant removal, the PUR PLUS is hard to beat as a first step toward chlorine-free drinking water. It’s the filter I recommend to anyone who says “I just want my water to stop tasting like a pool” and doesn’t want to deal with installation complexity.
5. Brita Elite Filter (in any Brita Pitcher) — Best Pitcher for Chlorine
The Brita Elite filter is the most cost-effective way to remove chlorine from drinking water, period. At $7-$9 per filter with a 120-gallon (6-month) life, annual filter cost is just $14-$18 — the lowest on this list by a wide margin. The Elite filter uses Brita’s Advanced Carbon Core Technology to remove 99% of chlorine taste and odor (NSF/ANSI 42 certified), plus it’s certified to NSF/ANSI 53 for lead (99%) and NSF/ANSI 401 for emerging contaminants including pharmaceuticals and pesticides. It also reduces PFOA and PFOS — a certification that puts the $8 Elite filter in the same conversation as filters costing ten times more.
The Elite filter fits most Brita pitchers and dispensers (NOT Brita Stream models). If you already own a Brita pitcher, you can upgrade to Elite filters immediately — no new hardware needed. If you’re buying new, the Brita 10-Cup Everyday pitcher with Elite filter costs $28-$38. The 10-cup capacity holds enough for a family’s daily drinking needs, and the 6-month filter life means you’re changing filters just twice a year.
For pure chlorine removal, the Brita Elite is the simplest, cheapest, most accessible option available. You fill the pitcher, wait 10-15 minutes for filtration, and pour. No installation, no plumbing, no electricity. The trade-off is convenience: you need to plan ahead (fill the pitcher before you need water), the pitcher takes refrigerator space, and the 10-cup capacity requires refilling for larger households. But at $14-$18 per year in filter costs, the Brita Elite removes the cost barrier entirely.
One important note: the Brita Standard filter (white) is significantly less effective than the Elite (blue). The Standard filter is NSF 42 certified for chlorine taste and odor only — it doesn’t carry NSF 53 or 401 certifications. If you’re buying Brita specifically for chlorine removal, make sure you’re using Elite filters. The performance difference is substantial.
6. Woder WD-G4-2512-DC Under-Sink Filter — Best for High-Capacity Single-Tap
The Woder WD-G4-2512-DC (formerly 10K-Gen3-DC) is built for people who want to install a filter and forget about it for as long as possible. With a rated capacity of 10,000 gallons, this single-cartridge under-sink filter can last 3+ years for a typical household before needing replacement. That’s the longest filter life of any under-sink system on this list — and it means fewer filter changes, less waste, and lower long-term hassle.
The Woder uses a proprietary granular activated carbon media that removes chlorine, lead, chromium-6, mercury, heavy metals, and VOCs while retaining beneficial minerals like calcium and magnesium. The direct-connect design attaches to your existing kitchen faucet’s cold water supply — no dedicated faucet required. Flow rate is approximately 2-3 GPM at standard household pressure, which is higher than most under-sink filters and means virtually no noticeable flow reduction at your tap.
The system retails for $80-$90 on Amazon. With a 10,000-gallon capacity and 3+ year life, the annual filter cost works out to approximately $25-$30 — competitive with the Brita Elite pitcher and far less than most under-sink systems. The filter is WQA certified for lead-free materials (NSF/ANSI 372), and Woder’s contaminant removal claims are tested by independent laboratories, though the system doesn’t carry full NSF 42 or 53 certification. Installation takes 10-15 minutes with the included direct-connect fittings.
The Woder’s chlorine removal performance is good but not perfect. Independent testing by TechGearLab found that the Woder removed chlorine effectively from moderately chlorinated water but struggled with very high chlorine levels. For typical municipal water (1-4 ppm chlorine), the Woder performs well. For heavily chlorinated water or chloramine treatment, a system with catalytic carbon (like the Frizzlife SK99 or SpringWell CF1) is more reliable. The Woder is best suited for users who prioritize low maintenance and long filter life over maximum chlorine removal performance.
7. Aquasana AQ-5200 Under-Sink Filter — Best Certified Under-Sink System
The Aquasana AQ-5200 carries the most comprehensive NSF certification portfolio of any under-sink filter on this list: NSF/ANSI 42 (chlorine taste and odor), NSF/ANSI 53 (health contaminants including lead), and NSF/ANSI 401 (emerging contaminants including pharmaceuticals). That triple certification means every contaminant removal claim has been independently verified under controlled laboratory conditions — not just tested by the manufacturer.
The 2-stage Claryum filtration system combines activated carbon, catalytic carbon, ion exchange, and sub-micron mechanical filtration to reduce 77 contaminants. For chlorine specifically, the AQ-5200 removes 99%+ of free chlorine and is one of the few under-sink systems that also effectively reduces chloramine — thanks to the catalytic carbon component. If your water utility uses chloramine instead of chlorine, the AQ-5200 is a stronger choice than systems using only standard activated carbon.
The system retails for $130-$160 depending on faucet finish. Each filter set is rated for 500 gallons or 6 months, costing $50-$65 per set. Annual filter cost runs $100-$130 — the highest for under-sink systems on this list, but you’re paying for the broadest certified contaminant removal. Installation takes about 20 minutes with a dedicated faucet (included in brushed nickel, chrome, or oil-rubbed bronze). The compact dual-cartridge design fits easily under most sinks.
The AQ-5200 is the right choice if certification matters to you — and it should. NSF certification means the filter has been tested by an independent, accredited laboratory under standardized conditions. Manufacturer claims without NSF backing are essentially marketing. The AQ-5200’s triple certification (42 + 53 + 401) covers aesthetic contaminants, health contaminants, AND emerging contaminants — the most complete verification available in this price range. The trade-off is higher ongoing filter costs and a dedicated faucet requirement.
Quick Comparison: All 7 Chlorine Removal Systems
Chlorine vs. Chloramine: Why It Matters for Your Filter Choice
About 30% of US water utilities have switched from chlorine to chloramine (a combination of chlorine and ammonia) for disinfection. Chloramine is more stable than chlorine — it lasts longer in the distribution system, which means better disinfection at the far ends of the pipe network. But that stability also makes it harder to remove with standard filtration.
Standard activated carbon removes free chlorine through a chemical reaction (adsorption) that happens quickly — even brief contact with carbon is effective. Chloramine requires either catalytic carbon (a specially processed form of activated carbon with enhanced surface chemistry) or significantly longer contact time with standard carbon. Most pitcher filters and basic faucet mounts use standard activated carbon and are NOT effective against chloramine.
On this list, the systems effective against chloramine are: SpringWell CF1 (catalytic carbon), Aquasana EQ-1000 (catalytic carbon + KDF), Frizzlife SK99-NEW (limited effectiveness), and Aquasana AQ-5200 (catalytic carbon component). The PUR PLUS, Brita Elite, and Woder are designed for free chlorine removal and should not be relied upon for chloramine. Check your water utility’s annual Consumer Confidence Report to determine which disinfectant your water contains.
Frequently Asked Questions
Does boiling water remove chlorine?
Yes, but slowly. Boiling water for 15-20 minutes will evaporate most free chlorine. However, boiling is NOT effective against chloramine — the ammonia bond makes chloramine much more stable and resistant to evaporation. Boiling also concentrates other contaminants (like lead and nitrates) as water volume decreases. A carbon filter is far more practical and effective for daily chlorine removal than boiling.
Does letting water sit out remove chlorine?
Free chlorine will dissipate from water left in an open container — but it takes 24-48 hours for significant reduction, and the rate depends on temperature, surface area, and initial chlorine concentration. Chloramine does NOT dissipate by sitting out. This method is sometimes used for aquarium water (fish are sensitive to chlorine) but is impractical for daily drinking water. A filter provides immediate, reliable chlorine removal.
Is chlorine in tap water dangerous?
At the levels used in municipal water treatment (typically 0.5-4.0 ppm), chlorine is not considered acutely dangerous by the EPA or WHO. However, chlorine reacts with organic matter in water to form disinfection byproducts (DBPs) like trihalomethanes (THMs) and haloacetic acids (HAAs), which the EPA regulates due to potential long-term health effects including increased cancer risk with prolonged exposure. Removing chlorine at the tap eliminates both the taste issue and the DBP concern.
Do I need a whole-house filter or just a drinking water filter?
If your primary concern is drinking water taste, a point-of-use filter (under-sink, faucet-mount, or pitcher) is sufficient and far more affordable. If you’re concerned about chlorine exposure through skin absorption in showers, want chlorine-free water for cooking on all burners, or have skin/hair sensitivity to chlorinated water, a whole-house system is worth the investment. Many homeowners start with a drinking water filter and upgrade to whole-house later as budget allows.
How do I know if my water has chlorine or chloramine?
Check your water utility’s annual Consumer Confidence Report (CCR), available at EPA’s CCR search tool. The report lists the disinfectant used and its concentration. You can also test at home with a $10-$15 chlorine/chloramine test kit from Amazon or a pool supply store. If your water smells like a swimming pool, it almost certainly contains chlorine or chloramine — the question is which one, because the filter technology differs.
The Bottom Line
Chlorine removal is the most straightforward filtration task — virtually any activated carbon filter handles it effectively. The real question is scope and budget. The SpringWell CF1 provides whole-house dechlorination that transforms your shower, bath, and kitchen water for roughly $85/year over its 10-year life. The Brita Elite pitcher removes chlorine from drinking water for $14-$18/year with zero installation. And the Frizzlife SK99-NEW or Aquasana AQ-5200 provide certified under-sink chlorine removal at the kitchen tap for $35-$130/year. Start with what fits your budget and upgrade as needed — any chlorine removal is better than none.
