How to Remove Chlorine & Chloramine Taste From Tap Water
Many homeowners notice a distinct chemical taste or odor in their tap water, especially when municipal water is treated with disinfectants like chlorine or chloramine. While these disinfectants are effective at making water safe to drink by killing harmful microbes, they often come with some unpleasant side effects. Beyond the taste, chlorine and chloramine can dry out your skin and hair, and they pose risks to fish and dialysis patients. If you’re struggling with this issue, it’s important to understand the cause, health considerations, and effective treatment options to enjoy clean, fresh-tasting water throughout your home.
What Causes Chlorine and Chloramine in Tap Water?
Municipal water systems commonly use chlorine or chloramine to disinfect drinking water. While chlorine is simply a form of elemental chlorine added to water, chloramine is a compound created by combining chlorine with ammonia. Both act as powerful disinfectants but have different chemical properties and treatment needs.
Because these compounds are added to keep water safe, they inevitably remain in the water supply, giving it a chemical taste and odor. In addition to taste and smell, these disinfectants can cause dry skin and hair for some people. The disinfection process also creates byproducts, including trihalomethanes (TTHM) and haloacetic acids (HAA5), which some homeowners may want to reduce for health reasons.
Signs and Impact of Chlorine and Chloramine in Water
If your water smells or tastes like a swimming pool or chemical cleaner, that’s a strong sign of chlorine or chloramine presence. Other signs include:
- Dry, itchy skin or brittle hair after bathing
- Irritation of sensitive skin or eyes
- Harm to sensitive aquatic pets such as fish, since both chemicals are toxic to them
- Concerns for dialysis patients, as chloramine can interfere with treatment
It’s important to note that simple airing out or off-gassing of water can significantly reduce chlorine levels, but this doesn’t work effectively for chloramine. Chloramine is more stable and requires specialized treatment to remove.
How to Treat Chlorine and Chloramine in Your Home
Removing chlorine and chloramine from your water supply requires different approaches:
- **For Chlorine:** Standard activated carbon filters are highly effective at removing free chlorine. These filters absorb chlorine molecules, improving taste and odor quickly.
- **For Chloramine:** Because chloramine is more chemically stable, it needs a higher-grade catalytic carbon filter. Catalytic carbon not only absorbs chloramine but also facilitates its chemical breakdown. It requires a longer contact time with water to work effectively.
A whole-house catalytic carbon filter is an excellent solution because it treats every tap in your home, protecting your water from chemical taste and odor while preventing dry skin and hair issues. The best whole-house catalytic carbon systems automatically backwash to maintain filter efficiency without needing cartridge replacements, making them low-maintenance and reliable.
For drinking water specifically, an additional polishing step such as a reverse osmosis (RO) system or a carbon block filter can be used after the whole-house filter. These remove any remaining trace chemicals and other contaminants, ensuring crisp, clean water at your kitchen sink or water dispenser.
How to Choose and Size a Catalytic Carbon Filter
Choosing the right catalytic carbon filter depends on your water usage and chlorine or chloramine levels. To get the best results:
1. **Test Your Water:** Have your water professionally tested to measure chlorine and chloramine concentrations. This testing guides the right filter model and capacity.
2. **Contact Time:** The filter’s design should allow sufficient contact time between water and catalytic carbon to effectively break down chloramine. Systems designed to maximize contact time work best.
3. **Flow Rate and Capacity:** Consider your household water flow rate and daily water consumption. Filters are rated to handle specific volumes, so selecting the correct size ensures effective treatment and longevity.
4. **Maintenance:** Look for whole-house catalytic carbon filters with automatic backwash features. These systems clean themselves regularly, reducing maintenance efforts and maintaining peak performance.
5. **Additional Polishing:** If chlorine or chloramine taste persists after whole-house treatment, consider installing a point-of-use reverse osmosis or carbon block filter under the sink for drinking and cooking water.

FAQ: Chlorine and Chloramine Removal
Why can’t I just let my water “air out” to remove chloramine?
Chlorine can be reduced by off-gassing as it evaporates from standing water, but chloramine is much more stable and does not readily off-gas. Effective removal of chloramine requires catalytic carbon filtration that chemically breaks it down.
Will a standard carbon filter remove both chlorine and chloramine?
Standard activated carbon filters are very effective at removing free chlorine but have limited effectiveness against chloramine. Chloramine requires special catalytic carbon and longer contact time to be removed properly.
Is a whole-house catalytic carbon filter necessary, or can I just filter water at the tap?
A whole-house catalytic carbon filter treats all water entering your home, ensuring every tap delivers water free of chlorine and chloramine, protecting your skin, hair, plumbing, and appliances. Under-sink or point-of-use filters can polish drinking water but do not address water quality throughout the house.
How do I find out if my water contains chlorine or chloramine?
You can request a water test to determine chlorine and chloramine levels. Many municipalities also provide water quality reports. For personalized advice, free expert help is available at https://watersoftenerplus.com/pages/water-assistant.
