Does a Shower Filter Remove Chloramine?
Know which disinfectant is in your water, and what the published ClearFlow result actually covers.
Free chlorine and chloramine are both used to disinfect drinking water, but they are chemically different. A result measured for one should not automatically be applied to the other.
ClearFlow’s up to 98% laboratory result refers specifically to free chlorine. It should not be read as a chloramine-reduction figure, because performance against chloramine can differ.
Chlorine and chloramine: what's the difference?
Both are used by water utilities to disinfect drinking water and help keep it safe as it travels through the network.
- Free chlorine is a chlorine-based disinfectant and is widely used.
- Chloramine is formed by combining chlorine with ammonia. It is more persistent in the pipe network, which can make it useful in long distribution systems.
| Free chlorine | Chloramine | |
|---|---|---|
| What it is | Chlorine-based disinfectant | Chlorine combined with ammonia |
| Persistence | Less persistent | Longer-lasting in the network |
| ClearFlow published result | Up to 98% reduction under specified conditions | Not covered by the 98% figure |
Is chloramine used in Australia?
Yes. SA Water states that chloramine has been used in some South Australian supplies since the 1980s and is also used in Sydney, Brisbane, Bendigo and much of Western Australia. Water treatment varies by supply zone, so the best way to know your disinfectant type is to check your own water utility.
Why it matters for shower filters
Filtration claims are specific to what was measured under stated conditions. A free-chlorine result cannot simply be assumed to represent chloramine performance.
What this means for ClearFlow
ClearFlow has been independently laboratory tested for free chlorine reduction, achieving up to 98% under specified conditions. The 98% figure is not applied to chloramine.
Regardless of the disinfectant type, the visible sediment stage is designed to capture particulate matter such as dirt and grit.
How to find out what's in your water
- Check your water utility's website for a water-quality profile or disinfectant information.
- Read your utility's annual drinking-water quality report.
- Contact the utility and ask whether your supply zone uses free chlorine or chloramine.
Frequently asked questions
Does FiltraZen ClearFlow remove chloramine?
The published laboratory result is for free chlorine reduction. The up to 98% figure should not be applied to chloramine, and chloramine performance may differ.
Can I tell by smell whether my water has chloramine?
Not reliably. Check with your water utility or use its local water-quality lookup.
Is chloramine safe?
SA Water states that SA Health and the World Health Organization recognise chloramine as a safe and effective disinfectant for drinking water when used appropriately.
More from the ClearFlow Knowledge Series
Testing & performance disclaimer. ClearFlow has been evaluated through laboratory testing under controlled conditions. Reported performance figures may vary with water quality, chlorine concentration, temperature, pressure, flow rate, cartridge age and other factors. The up to 98% free-chlorine reduction figure represents a maximum laboratory result under the specified test conditions and is not a guarantee of the same reduction in every household or water supply.
ClearFlow is designed to reduce free chlorine and capture sediment and particulate matter. It is not a water softener and is not designed to remove hardness minerals such as calcium and magnesium. Chloramine performance may differ from free-chlorine performance.
