During the water treatment process, chlorine and ammonia are combined to create potent compounds called chloramines. Chloramines are commonly added to tap water for bacteria control due to their longer-lasting effect compared to chlorine alone. Many towns and cities across Australia now use chloramine filtration for homes as part of their disinfection process.
However, chloramines can come with side effects. They can also reduce the lifespan of water filters if the system is not designed to handle them.
Read on to learn how chloramine filtration works and which options are best for your setup.
Why Are Chloramines a Concern?
Chloramines often go unnoticed until they start causing evident health and quality concerns. Some people notice an odd taste or odour in their drinking water. Others experience skin irritation or stomach discomfort.
These chemical compounds can also affect your plumbing system. Over time, these may wear down copper pipes, rubber seals and heating elements, which could lead to leaks or equipment failure. In aquariums, hydroponics or similar setups, even small amounts of chloramines can be harmful to fish and plants.
When Is Chloramine Filtration Essential?
In certain systems, even small traces of chloramines can cause major problems – requiring advanced filtration to keep water safe and usable. Standard filters might not work reliably in the following situations:
- If your home gets water treated with chloramines
- If someone in your household has skin or sensitivity concerns
- If you keep fish or grow plants using aquaponics or hydroponics
- If you work with food and drink, where taste and purity matter
- If you use ultra-pure water for medical purposes like dialysis
In these cases, it's worth using a filter designed to remove chloramines. If you're unsure what's in your water, check with your local provider.
Best Filtration Methods for Chloramines
There are a few ways to filter out chloramines – some are more effective than others. The best option depends on your system’s needs and application.
Catalytic Carbon Filters
Catalytic carbon is often the go-to choice for removing chloramines. It’s not the same as regular carbon, since it’s been specially treated to break down the chloramine into harmless components. These filters work well when installed at the main water line or under the sink.
- Pros: Quick filtration, good for higher flow rates, lasts a long time
- Cons: Works best when the system is sized correctly and water has enough contact time
At Aquastream, we offer a range of carbon cartridges, including catalytic options suitable for both homes and commercial settings.
Granular Activated Carbon (GAC)
GAC filters are made of loose carbon granules and need more time to filter out chloramines. For best results, they should be replaced on schedule and matched to your flow rate.
- Pros: Widely available and affordable
- Cons: Less effective without large capacity systems

Reverse Osmosis (RO)
Reverse osmosis systems are effective at filtering out a broad range of contaminants, including the ammonia component of chloramines. However, they usually rely on a pre-filter (typically catalytic carbon) to break the chloramine bond first.
- Pros: Produces highly purified water
- Cons: Slower output, requires pre-treatment to remove chloramines
RO systems are ideal for specialised applications like aquariums, hydroponics or food processing.
System Compatibility
Your chloramine filtration system should be compatible with your plumbing. Under-sink filters work well for some homes, while others may need a whole-house setup at the main water line.
The flow rate of your system, space availability and ease of maintenance should all be part of the decision. If your water use is high or you require filtered water throughout the property, a larger setup with greater contact time is recommended.
