Chloramine Water Filter Australia (2026):
How to Get It Out of Your Drinking Water
To get chloramine out of your drinking water, use a multi-stage filter with a published chloramine result, not a basic carbon jug. Chloramine is the longer-lasting cousin of chlorine that parts of Sydney, South East Queensland and regional South Australia use to disinfect tap water, and it's built to resist breaking down. Here's how it works, what actually removes it, and the benchtop filter that cut it by 99.0% in independent lab testing.
HolyH₂O Trinity
Benchtop filter · Multi-stage media · No plumbing, no power
Independently tested by AS Enviro (ISO/IEC 17025:2017 accredited): chloramine down 99.0%, chlorine down more than 99.9%, fluoride down 99.5%. Then it adds calcium and magnesium back for a smoother taste. Fill it, wait, pour.

Chloramine (chlorine bonded with ammonia) is more stable than chlorine, so it doesn't gas off in the fridge and basic carbon jugs struggle with it. The fix is multi-stage filtration with enough contact time and a measured chloramine result. The HolyH₂O Trinity reduced chloramine by 99.0% in third-party testing, and the 100% Glass Trinity uses the same media in a glass build. For the full benchtop line-up, see our best benchtop water filter guide.
About these numbers: reduction figures come from third-party testing of the Trinity system by AS Enviro, an ISO/IEC 17025:2017 accredited laboratory, run to NSF/ANSI 42, 53 and 401 test methods. Results vary with source water and usage. View the full report.
What Chloramine Is and Why It's in Your Water
Chloramine is a disinfectant made by adding a small amount of ammonia to chlorine. Utilities use it because it lasts longer in long pipe networks, which keeps water safe all the way to the furthest taps. That same staying power is why it's harder to filter out at home.
Monochloramine is the form used in drinking water. It's a deliberate, controlled treatment step, not a contaminant that slipped through.
Free chlorine fades over long pipelines. Chloramine persists, which is why it suits big, spread-out networks.
Like chlorine, it contributes to that "tap water" taste in your glass, coffee and tea. Filtering it out is mostly about drinking water you enjoy.
The old trick of leaving a jug in the fridge works on free chlorine. Chloramine is far more stable, so it stays put.
Which Australian Areas Use Chloramine?
Chloramine shows up in parts of the Sydney Water network, parts of South East Queensland supplied by Seqwater, and mainly regional areas of South Australia. Many networks use free chlorine instead, and some zones switch between the two, so your utility's water quality report is the final word for your suburb.
| Area | Utility | Disinfectant | Local guide |
|---|---|---|---|
| Sydney | Sydney Water | Chlorine, plus chloramine in parts of the network | Sydney tap water |
| Brisbane + SEQ | Seqwater | Chlorine, plus chloramine in parts of the network | Brisbane tap water |
| Gold Coast | Seqwater supply | Check your local water quality report | Gold Coast tap water |
| Adelaide + SA | SA Water | Chlorine, with chloramine mainly in regional areas | Adelaide tap water |
Disinfection practice changes by zone and over time. Check your utility's latest water quality report for your suburb.
Not sure which you've got? Either way, a filter that handles both covers you. Trinity reduced chlorine by more than 99.9% and chloramine by 99.0% in the same test, so you don't need to know which one your utility uses. Our guide to chlorine in Australian tap water covers the chlorine side.
What Removes Chloramine (and What Doesn't)
Chloramine needs filter media designed for it plus enough contact time. That's why benchtop gravity systems, where water trickles slowly through several stages, have an edge over fast-flowing jugs. Here's how the common options compare.
| Method | HolyH₂O Trinity | Basic carbon jug | Boiling / leaving out | Reverse osmosis |
|---|---|---|---|---|
| Chloramine | ✓ 99.0% (lab tested) | ⚠ Varies, often limited | ✗ Not reliable | ✓ Usually with carbon pre-filters |
| Chlorine | ✓ >99.9% | ✓ Usually | ⚠ Slowly | ✓ Yes |
| Fluoride | ✓ 99.5% | ✗ Typically no | ✗ No | ✓ Yes |
| Minerals | ✓ Calcium + magnesium added back | ⚠ Unchanged | ⚠ Unchanged | ✗ Typically removed |
| Plumbing needed | ✓ None | ✓ None | ✓ None | ✗ Usually |

Five things separate a filter that handles chloramine from one that just says "chlorine" on the box.
"Reduces chlorine" isn't the same claim. Look for chloramine listed separately, with a percentage.
ISO/IEC 17025 accreditation means the lab itself has been audited. Trinity's report is public.
Slow gravity flow through several stages gives the media time to work on stubborn chloramine.
Australian water carries more than one disinfectant story. Trinity also cut fluoride 99.5% and THMs 99.6%.
No drilling, no plumber, no bond worries. A benchtop filter moves house with you.

Chloramine Myths to Skip
Most chloramine advice online was written for chlorine. Here's what doesn't carry over.
- "Leave a jug in the fridge overnight." That helps with free chlorine, not chloramine.
- "Boiling sorts it out." Chloramine is stable, so boiling isn't a reliable fix, and it does nothing for fluoride.
- "Any carbon filter handles it." Basic carbon works on chloramine far more slowly than on chlorine. Look for a measured result.
- "My shower filter covers my drinking water." Different water, different filter. Shower filters protect your skin and hair; a benchtop filter covers your glass.
- "Chlorine on the box means chloramine too." Only if chloramine is listed separately.
The takeaway: if your area uses chloramine, choose a drinking water filter with a lab-tested chloramine number. Trinity's is 99.0%, and the full report is public. 💧
FAQs
What is the best water filter for chloramine in Australia?
Look for a filter with a published chloramine result from an accredited lab. The HolyH₂O Trinity benchtop filter reduced chloramine by 99.0% in third-party testing by AS Enviro (ISO/IEC 17025:2017 accredited), along with more than 99.9% of chlorine and 99.5% of fluoride. It sits on your bench with no plumbing or power.
Does a normal carbon jug filter remove chloramine?
Results vary. Chloramine is far more stable than chlorine, and standard activated carbon works on it much more slowly, so a basic jug may not do much in the short time water spends in the cartridge. Multi-stage media and a longer contact time make the difference, so look for a filter that lists a measured chloramine result.
Does boiling or leaving water out remove chloramine?
Not reliably. Free chlorine can gas off from a jug left in the fridge, but chloramine is built to last in the pipes, so it hangs around far longer. Filtration with media designed for it is the dependable way to get it out of your drinking water.
Does Sydney tap water have chloramine?
Sydney Water uses chloramine in parts of its network, and Seqwater does the same in parts of South East Queensland. SA Water uses it mainly in regional areas. Your utility's water quality report for your suburb tells you which disinfectant reaches your tap, and our Sydney tap water guide has more.
Is chloramine in tap water safe to drink?
Australian tap water meets the Australian Drinking Water Guidelines, which set a health guideline value of 3 mg/L for monochloramine, and utilities dose to stay within it. Many households still choose to filter it out because chloramine contributes to the taste and smell of tap water.
Does Trinity remove chloramine and fluoride?
Yes. In the same AS Enviro test, Trinity reduced chloramine by 99.0%, fluoride by 99.5% (2.0 to 0.01 mg/L) and chlorine by more than 99.9%. You can view the full report.
Does the 100% Glass Trinity remove chloramine?
Yes. The 100% Glass Trinity uses the same filtration media as Trinity, so the 99.0% chloramine result applies. The difference is the build: a glass tank and a glass filter cartridge housing.
Do I need a shower filter for chloramine too?
A benchtop filter covers the water you drink and cook with. For the shower, Shower Mate uses KDF and catalytic carbon to reduce both chlorine and chloramine. Our chloramine shower filter guide covers that side.
