Questions & answers
Eagle Reborn — frequently asked questions
How the anodised-aluminium shower filter works, what's inside the cartridge, how to install it, and more. Designed in Australia.
What does the Eagle Reborn shower filter do?
It's a premium anodised-aluminium inline shower filter, designed in Australia. Its four-stage media reduces chlorine and helps reduce chloramine, for cleaner, softer-feeling water that's gentler on skin and hair.
Does it reduce chlorine?
Yes. The KDF-55 and calcium sulfite stages reduce chlorine as water passes through.
Does it help with chloramine?
Yes. A Vitamin C (ascorbic) stage helps reduce chloramine — the disinfectant many Australian cities such as Sydney, Brisbane, Adelaide, Perth and Darwin use — finished with an activated-carbon polish.
What's inside the cartridge?
Four layered stages — 130 grams of media: KDF-55 (reduces chlorine), calcium sulfite (dechlorination), Vitamin C (helps reduce chloramine) and activated carbon (final polish). The media is layered in order, not mixed.
Will it reduce my water pressure?
No. The solid anodised-aluminium chamber holds full pressure — it doesn't bulge or restrict flow the way thin plastic filters can.
What is it made of?
The body is machined from anodised aluminium — engineered metal that won't crack, leak or go brittle like cheap plastic filters.
How long does a cartridge last?
About three months, depending on your water and how much you use it.
How do I replace the cartridge?
It swaps out in around 60 seconds, no tools needed. You can order replacements from the cartridges page.
Will it fit my shower?
Yes. It fits any standard G½ fitting and installs inline between your shower arm and shower head in about 60 seconds.
Is it designed in Australia?
Yes. Eagle Reborn is designed in Australia and built for Australian water.
Why aluminium instead of plastic?
Most shower filters are moulded from cheap plastic, which can crack, go brittle and choke water flow over time. The Eagle Reborn body is machined from anodised aluminium — engineered metal that holds full pressure, shrugs off heat cycles and knocks, and is built to stay on your wall instead of ending up in landfill.
Why does the cartridge use different media for chlorine and chloramine?
Because they are different disinfectants. KDF-55 and calcium sulfite reduce chlorine quickly as water passes through. Chloramine is more stable and harder to address, so a dedicated Vitamin C stage helps reduce it, followed by an activated-carbon final polish.
How does KDF-55 reduce chlorine?
KDF-55 is a high-purity copper-zinc medium that works by a redox (oxidation-reduction) reaction: as water flows through, it converts free chlorine into harmless chloride. It works quickly, even at shower flow and temperature.
Does Vitamin C actually help with chloramine?
Ascorbic acid (Vitamin C) is a recognised way to dechlorinate water — utilities use it, and it is included in industry dechlorination standards. It reacts quickly with chlorine; chloramine is more stable, so the Vitamin C stage helps reduce it, backed by an activated-carbon final polish.
Which Australian cities use chloramine?
Australian utilities use two disinfectants — free chlorine and chloramine. Which reaches your tap depends on your retailer and suburb, not just your city, and can vary by zone and season. Chloramine is common across much of Sydney, Adelaide and Brisbane; Melbourne and Hobart largely use free chlorine — though Melbourne's western growth suburbs (Greater Western Water) are chloraminated. Check your retailer's annual water quality report to confirm. The four-stage cartridge reduces chlorine and helps reduce chloramine, so it works either way.
Is it a water softener? Does it fix hard water?
No — it is a shower filter, not a water softener. It reduces chlorine and helps reduce chloramine for softer-feeling water, but it does not remove hardness minerals like calcium and magnesium. If your main issue is scale from hard water, that needs a different type of system.
Is the chlorine or chloramine in Australian tap water dangerous?
Australian tap water is treated to be safe to drink, and disinfectant levels sit well within national guidelines. Many people simply prefer to shower in water with less chlorine — for cleaner, softer-feeling water that is gentler on skin and hair.
