Chlorine and chloramine are commonly used by U.S. water utilities to disinfect public drinking water. They are not the same chemical, and that distinction matters when choosing a home water filter.
A filter that is excellent at reducing chlorine taste and odor may not be equally effective against chloramine. If your utility uses chloramine, you should specifically look for a system whose manufacturer or independent certification documentation identifies chloramine reduction.
This guide focuses on actual water-filter systems available for American homes, with attention to filtration technology, certification, installation, replacement requirements, and the situations in which each system makes sense.
Quick Answer: Best Water Filters for Chlorine and Chloramine
| Product | Best For | Type | Chlorine | Chloramine |
|---|---|---|---|---|
| Aquasana Rhino Chloramines | Best whole-house chloramine system | Whole-house | Yes | Yes |
| Aquasana Claryum 3-Stage Max Flow | Best under-sink option | Under-sink | Yes | Yes |
| Aquasana Claryum Direct Connect | Best easy-install option | Under-sink | Yes | Yes |
| Aquasana Clean Water Machine | Best countertop option | Countertop | Yes | Limited/specification dependent |
| Aquasana Rhino | Best whole-house chlorine filtration | Whole-house | Yes | Not the primary choice |
Important: chlorine and chloramine performance should not be inferred simply from the presence of carbon. Always check the specific model’s performance documentation and certification scope.
How We Selected These Water Filters
We prioritized systems that are useful for real U.S. drinking-water situations rather than simply choosing filters based on marketing claims.
- Ability to reduce chlorine, chloramine, or both
- Published performance information
- Relevant NSF/ANSI or other independent certification where available
- Appropriate filtration technology
- Replacement-filter availability
- Installation requirements
- Whole-house versus point-of-use suitability
- Practical limitations that homeowners should understand before buying
If you do not know whether your utility uses chlorine or chloramine, start with your local water-quality information. Our guide on how to choose a water purifier based on your U.S. water-quality report explains how to use that information.
1. Aquasana Rhino Chloramines — Best Whole-House Filter for Chloramine
Why We Selected It
We selected the Aquasana Rhino Chloramines because it is specifically designed for homes where chloramine is an important concern. That makes it more appropriate than choosing a conventional whole-house carbon system solely on the assumption that all carbon filters perform similarly against chloramine.
Aquasana publishes performance information for reduction of both chlorine and chloramine, making this one of the more directly relevant choices for households whose municipal water system uses chloramine.
Relevant Certification
Aquasana states that the Rhino Chloramines system is independently tested to applicable NSF/ANSI 42 requirements for specified performance claims. Aquasana’s published performance information identifies reduction of chlorine and chloramines under specified testing conditions.
The important point is to distinguish NSF/ANSI 42 certification/testing for a particular contaminant claim from a general statement that the entire system removes every substance covered by NSF/ANSI 42.
Important Limitations
- It is a whole-house filtration system, so installation is more involved than installing a pitcher or under-sink filter.
- It is primarily intended for treating incoming household water rather than being a simple drinking-water-only solution.
- Performance depends on water chemistry, flow rate, installation, and other operating conditions.
- It does not mean that the source of chlorine or chloramine has been eliminated from the municipal water supply.
- Homes with contaminants unrelated to chlorine or chloramine may need additional treatment.
- Professional installation may be appropriate depending on the home’s plumbing configuration.
Who Should Buy It
- Homeowners with municipal water treated with chloramine
- Households wanting filtration throughout the home
- People particularly concerned about chlorine or chloramine taste and odor
- Homes where treating shower, bath, laundry, and other household water is desirable
Who Shouldn’t Buy It
- Renters who cannot modify their main water line
- People who only want filtered water at one kitchen faucet
- Households looking primarily for PFAS, nitrate, arsenic, or other contaminant-specific treatment
- People unwilling to deal with whole-house installation and maintenance
Replacement Filter Considerations
The Rhino Chloramines system uses replaceable filtration media rather than a small cartridge comparable to a countertop pitcher. Aquasana publishes a service life of up to 1,000,000 gallons or up to 10 years under specified conditions for the system’s filtration media.
Actual service life can vary substantially depending on household water quality and usage. Before purchasing, check the current replacement-media configuration and availability for the exact Rhino Chloramines model you intend to install.

2. Aquasana Claryum 3-Stage Max Flow — Best Under-Sink Filter
Why We Selected It
We selected the Aquasana Claryum 3-Stage Max Flow for households that do not need whole-house filtration but want a more capable drinking-water system installed under the kitchen sink.
Its multi-stage filtration approach makes it a particularly useful choice when chlorine or chloramine reduction is only one part of the homeowner’s water-quality goals.
Relevant Certification
Aquasana states that the Claryum 3-Stage Max Flow is WQA tested and certified to applicable NSF/ANSI 42, 53, and 401 requirements for specified contaminant-reduction claims.
Aquasana’s published performance information includes chlorine and chloramine reduction under specified testing conditions. The certification should therefore be interpreted according to the individual claims covered by the certification rather than as certification for every possible contaminant.
Important Limitations
- This is a point-of-use system rather than a whole-house filter.
- It treats water at the connected faucet rather than shower and bath water.
- Cartridges must be replaced periodically.
- Installation requires access beneath the sink and connection to the water supply.
- Performance depends on incoming water conditions and proper cartridge replacement.
Who Should Buy It
- Homeowners who mainly want better drinking and cooking water
- People who want chlorine/chloramine reduction without installing whole-house equipment
- Households that also want filtration for additional specified contaminants
- Homeowners who want faster dispensing than many basic under-sink systems
Who Shouldn’t Buy It
- People who want filtered shower and bath water
- Renters without permission to install an under-sink system
- Households requiring treatment for contaminants outside the system’s certified claims
- People who do not want recurring cartridge replacements
Replacement Filter Considerations
The Claryum 3-Stage Max Flow uses a multi-cartridge replacement set. Aquasana specifies a replacement interval based on approximately 800 gallons or six months, depending on which limit is reached first.
Actual replacement frequency can vary with household consumption and incoming-water quality. Replacement cartridges should be purchased for the exact model family because cartridges are not universally interchangeable across Aquasana systems.

3. Aquasana Claryum Direct Connect — Best Easy-Installation Under-Sink Option
Why We Selected It
We selected the Aquasana Claryum Direct Connect for homeowners who want under-sink filtration without adding a separate dedicated drinking-water faucet.
It connects to the existing cold-water supply and therefore provides a simpler installation approach than systems that require a separate faucet and larger multi-stage assembly.
Relevant Certification
Aquasana states that the Claryum Direct Connect is IAPMO certified to applicable NSF/ANSI 42, 53, and 401 requirements for specified claims.
This certification is particularly useful because it provides independent verification for defined performance claims rather than relying solely on manufacturer marketing.
Important Limitations
- It is a point-of-use system.
- It does not provide filtered water to the entire home.
- Because it connects to the existing faucet supply, the filter is not appropriate when you specifically want separate filtered and unfiltered cold-water delivery at the faucet.
- Replacement cartridges are required.
- It is not a substitute for treatment designed specifically for contaminants outside its certified claims.
Who Should Buy It
- Homeowners wanting a relatively simple under-sink installation
- People who primarily want better water at the kitchen faucet
- Households that dislike countertop pitchers
- People who do not want to install a dedicated filtered-water faucet
Who Shouldn’t Buy It
- People wanting whole-house chlorine/chloramine reduction
- People who need reverse osmosis
- Households with contaminant concerns requiring specialized treatment
- People who do not want filtration applied to the connected cold-water line
Replacement Filter Considerations
The Direct Connect uses a replaceable cartridge designed specifically for the system. Replacement intervals depend on the exact model and household usage, so buyers should confirm the current cartridge specification before purchasing.
Do not assume that a replacement cartridge from another Claryum model will fit simply because the brand and filtration technology are similar.

4. Aquasana Clean Water Machine — Best Countertop Option
Why We Selected It
We selected the Aquasana Clean Water Machine for people who want a countertop solution without modifying their under-sink plumbing.
This makes it particularly interesting for renters, temporary housing, offices, and homeowners who want a filtration system that can be installed with considerably less plumbing work than a whole-house or conventional under-sink system.
Relevant Certification
Aquasana states that the Clean Water Machine is WQA tested and certified to applicable NSF/ANSI 42, 53, and 401 requirements for specified claims.
The certification covers defined contaminant-reduction claims. Buyers should not interpret the certification as meaning that the system removes every contaminant that may occur in U.S. drinking water.
Important Limitations
- It is a countertop point-of-use system.
- It does not treat shower, bath, laundry, or other household water.
- Counter space is required.
- Filter cartridges require periodic replacement.
- It is not a substitute for whole-house filtration when the goal is treatment throughout the plumbing system.
Who Should Buy It
- Renters
- People who cannot modify plumbing
- Apartment residents
- People wanting filtered drinking water without under-sink installation
- Households that value portability and simple setup
Who Shouldn’t Buy It
- Homeowners wanting whole-house chlorine or chloramine treatment
- People who dislike having equipment on the kitchen counter
- Households requiring high-volume filtered water throughout the home
- People whose primary concern requires a specialized treatment technology such as RO or ion exchange
Replacement Filter Considerations
The system uses replaceable filtration components, so ongoing ownership cost should be considered alongside the initial purchase price.
Replacement frequency depends on the cartridge specification, household consumption, and incoming water quality. Buyers should verify the current replacement cartridge and recommended service interval before purchasing.

5. Aquasana Rhino — Best Whole-House Chlorine Filtration
Why We Selected It
We selected the Aquasana Rhino for homeowners whose primary concern is conventional chlorine in municipal water and who want filtration at the point where water enters the home.
It is a better fit than an under-sink system when the homeowner wants to reduce chlorine exposure or taste throughout the household rather than only at the kitchen faucet.
Relevant Certification
Aquasana states that the Rhino is independently tested to applicable NSF/ANSI 42 requirements for chlorine-reduction performance. Published Aquasana information identifies reduction of chlorine under specified testing conditions.
This is an important distinction when comparing it with chloramine-specific systems: chlorine performance should not automatically be interpreted as equivalent chloramine performance.
Important Limitations
- It is primarily a whole-house chlorine filtration system.
- It is not the first choice when chloramine is the main disinfectant concern.
- Installation requires connection to the home’s main water line.
- It does not provide comprehensive treatment for every possible drinking-water contaminant.
- Maintenance and replacement-media costs should be included in the ownership calculation.
Who Should Buy It
- Homeowners with municipal water treated primarily with chlorine
- People wanting whole-house chlorine reduction
- Households concerned about chlorine taste and odor at multiple fixtures
- Homeowners who prefer a whole-house system over point-of-use filtration
Who Shouldn’t Buy It
- Homes where chloramine is the primary disinfectant and chloramine reduction is important
- Renters who cannot alter the main water line
- People who only want inexpensive drinking-water filtration
- Households needing specialized treatment for PFAS, nitrates, arsenic, or other contaminants
Replacement Filter Considerations
The Rhino uses long-life whole-house filtration media rather than small drinking-water cartridges. Aquasana publishes a long service-life rating for the system under specified conditions.
Actual service life depends on water quality and household consumption. Before buying, verify the exact Rhino configuration and replacement-media availability for your installation.

Chlorine vs Chloramine: Why the Difference Matters
Chlorine and chloramine are both used for drinking-water disinfection, but they behave differently in filtration systems.
| Characteristic | Chlorine | Chloramine |
|---|---|---|
| Used for municipal disinfection | Yes | Yes |
| Same as the other chemical? | No | No |
| Carbon filtration effectiveness | Generally easier to reduce | Requires appropriate media/contact time |
| Should you verify the filter’s specific claim? | Yes | Especially important |
This is why a filter advertised simply as a “carbon filter” should not automatically be assumed to provide strong chloramine reduction.
Whole-House vs Under-Sink Filtration
| Feature | Whole-House | Under-Sink |
|---|---|---|
| Drinking water | Yes | Yes |
| Shower water | Yes | No |
| Bath water | Yes | No |
| Installation | More involved | Moderate |
| Filter replacement | Less frequent for some systems | More frequent |
| Best for renters | No | Sometimes |
| Best for drinking water only | Usually unnecessary | Yes |
If you are deciding specifically between the two approaches, see Under-Sink Water Filter vs Reverse Osmosis System and consider whether you actually need RO rather than carbon filtration.
Do You Need Reverse Osmosis for Chlorine or Chloramine?
Not necessarily.
If chlorine or chloramine taste and odor are your primary concerns, an appropriately designed carbon-based filtration system may be a more practical solution than reverse osmosis.
Reverse osmosis becomes more attractive when your water-quality report identifies additional dissolved contaminants that require or benefit from RO treatment.
For a broader comparison, see Reverse Osmosis vs Carbon Filtration for U.S. Tap Water.
How to Choose the Right Filter
Step 1: Find Out Which Disinfectant Your Utility Uses
Check your utility’s annual Consumer Confidence Report or contact the water provider.
Knowing whether the system uses chlorine, chloramine, or changes disinfectants during different treatment periods can significantly affect your filter choice.
Step 2: Decide Whether You Need Whole-House Filtration
If you only care about drinking and cooking water, an under-sink or countertop filter can be sufficient.
If you want chlorine or chloramine reduction at showers, baths, and other fixtures, consider a whole-house system.
Step 3: Check the Actual Performance Claim
Do not stop at phrases such as “advanced carbon filtration.” Look for a documented chlorine or chloramine reduction claim for the exact model.
Step 4: Check Certification
NSF/ANSI 42 is particularly relevant to aesthetic effects such as chlorine taste and odor. However, certification is always tied to defined claims and testing conditions.
For a deeper explanation, see NSF 42 vs NSF 53: Which Water Filter Certification Do You Need?
Step 5: Calculate Long-Term Filter Costs
The purchase price is only part of the cost. Consider replacement cartridges or media, installation, and any prefilters required by the system.
See How Much Does It Cost to Replace Water Filter Cartridges in the USA? for a broader cost framework.
Common Buying Mistakes
- Assuming all carbon filters remove chloramine equally
- Choosing a whole-house system when only drinking-water filtration is needed
- Choosing an under-sink filter when whole-house treatment is the actual goal
- Looking only at the initial purchase price
- Ignoring replacement-filter availability
- Assuming NSF certification means the filter removes every contaminant
- Ignoring the home’s water pressure and plumbing configuration
- Failing to check the exact model’s performance documentation
Practical Buying Checklist

- ☐ Check replacement-filter availability
- ☐ Estimate annual replacement costs
- ☐ Confirm installation requirements
- ☐ Consider whether additional contaminants require another treatment technology
Frequently Asked Questions
Does a water filter remove chlorine?
Many carbon-based water filters can substantially reduce chlorine, but performance varies by filter design, contact time, flow rate, and water chemistry. Look for a documented performance claim for the specific model.
Does a carbon filter remove chloramine?
Some carbon systems can reduce chloramine, but chloramine is generally more difficult to remove than free chlorine. Do not assume a standard carbon filter has strong chloramine performance unless the manufacturer or certification documentation specifically supports it.
Is NSF 42 important for chlorine?
Yes. NSF/ANSI 42 is commonly associated with aesthetic contaminant reduction, including chlorine taste and odor. However, you should still verify the exact claim and certification scope for the specific filter.
Should I use a whole-house filter or under-sink filter?
Choose whole-house filtration if you want treatment at multiple fixtures. Choose under-sink filtration if your primary goal is better drinking and cooking water at the kitchen sink.
Does reverse osmosis remove chlorine?
RO systems generally use carbon prefiltration because chlorine can damage certain RO membranes. Therefore, an RO system normally requires appropriate pretreatment rather than relying on the RO membrane alone to handle chlorine.
Does a water softener remove chlorine?
No. A conventional water softener is designed primarily to address hardness minerals such as calcium and magnesium. It should not be purchased as a substitute for chlorine or chloramine filtration.

Final Verdict
The best chlorine or chloramine filter depends first on what your water utility actually uses and second on where you want the water treated.
Aquasana Rhino Chloramines is the strongest choice in this group when whole-house chloramine reduction is the priority.
Aquasana Claryum 3-Stage Max Flow is a strong choice when you want a more capable under-sink drinking-water system.
Aquasana Claryum Direct Connect makes sense when simple under-sink installation is the priority.
Aquasana Clean Water Machine is attractive for renters and people who need countertop filtration.
Aquasana Rhino is the better fit when conventional chlorine reduction throughout the home is the main objective and chloramine is not the primary concern.
The most important lesson is simple: do not choose a filter just because it says “carbon” or “chlorine reduction.” Match the system to your water report, verify the specific performance claim, check certification scope, and calculate the long-term replacement cost.
