If your bath fills from a spout, a clip-on bath tap filter is the simplest way to get filtered bath water. HolyH₂O Bath Mate straps onto most standard bath taps, uses KDF-55 and catalytic carbon to reduce chlorine (by up to 99%) and chloramine, and takes about a minute to fit. If your bath fills from a handheld shower instead, filter the shower with Shower Mate.
About the 99% figure: it is the upper end of chlorine reduction for Bath Mate's KDF and catalytic carbon media. Real results depend on your local water and how fast the tap runs, so think of it as best case, not a promise for every home.
What Is a Bath Tap Filter?
A bath tap filter is a compact cartridge that attaches to the end of your bath spout, so every litre that fills the tub passes through filter media first. It reduces chlorine, chloramine, sediment and rust at the tap, which means the water you soak in has already been filtered before it reaches your skin.
That matters more in a bath than in a quick rinse. In a shower the water runs off you. In a bath, you sit in it for a while. Filtering at the spout is the cleanest way to change the whole tub in one go, with nothing to drop in the water and nothing to dissolve.
The water passes through the cartridge on its way into the tub, so the whole bath is filtered from the first litre.
KDF-55 plus catalytic carbon handles both disinfectants Aussie utilities use, whichever your city runs.
The KDF-55 in Bath Mate is built to keep working in warm bath water.
Say goodbye to that pool-like chlorine smell rising off the water as the bath runs.
Will It Fit My Bath Tap?
Bath Mate fits most standard bath taps. It attaches with an adjustable strap that tightens around the spout, so what matters is having a spout the strap can wrap around snugly. If your bath fills from a handheld shower or an over-bath shower, filter the shower instead.
| Your bath setup | Best HolyH₂O fit | Why |
|---|---|---|
| Standard bath spout (wall or deck mounted) | ✓ Bath Mate | The strap tightens around the spout for a snug, tool-free fit. |
| Bath mixer with a spout | ✓ Bath Mate | If the strap can wrap the spout, it fits like any standard tap. |
| Bath filled from a handheld shower | ✓ Shower Mate | Filter the shower and every fill from it is filtered too. |
| Shower over the bath | ✓ Bath Mate + Shower Mate or Shower Max | Same media in both, so baths and showers get the same filtered water. |
| Unusual or designer spout | ⚠ Ask us first | Email a photo to hi@holyh2o.com.au and we will check the fit. |
Bath Mate makes no permanent changes to your tap, so renters can fit it and take it to the next place.

Fitting Bath Mate takes about a minute: clip it over your tap and tighten the strap, run the water for about a minute to clear the fresh media, then fill your bath as usual. There is nothing to unscrew and no seal tape to fuss with.
Fit Bath Mate over your bath tap and tighten the adjustable strap until it sits snug on the spout.
Let the water flow for about a minute to flush the fresh media before your first bath.
Run your bath as normal and hop in. That is it, every fill from now on is filtered.

How a Bath Tap Filter Works
Bath Mate pushes your bath water through two media working as a team. KDF-55, a high-purity copper-zinc blend, uses a redox reaction to reduce chlorine and heavy metals and keeps working in warm water. Catalytic carbon then tackles chloramine and traps the odours tap water leaves behind.
| Media | What it does in Bath Mate | Targets |
|---|---|---|
| KDF-55 | Copper-zinc redox reaction, warm-water ready | Chlorine, heavy metals |
| Catalytic carbon | Enhanced activated carbon built for tougher disinfectants | Chloramine, chlorine, odours |
| Both media together | Catch particles before they settle in the tub | Sediment, rust |

Bath Tap Filter vs Shower Filter
Bath Mate and our shower filters share the same KDF and catalytic carbon media, so the difference is simply where they fit. Bath Mate straps onto the bath spout; Shower Mate sits between your shower arm and existing head; Shower Max replaces the head entirely. Filter both and the whole bathroom runs on the same filtered water.

Cartridge Changes and Care
Replace the Bath Mate cartridge every 3 to 6 months, depending on how often your household runs a bath. A family that baths nightly sits at the shorter end; an occasional weekend soak stretches toward six months.
More baths means a faster swap. Mark the date you fit it so you know when it is due.
A fresh cartridge arrives on schedule, so you never run on a spent filter.
Run each new cartridge for about a minute before filling the tub, same as day one.
Loosen the strap and take it with you. Nothing stays behind on the tap.
Takeaway: a bath tap filter is the easiest filter in the house to own. Strap it on, flush it once, swap the cartridge a few times a year, and every bath runs through KDF and catalytic carbon first.
Common Mistakes to Avoid
- Skipping the first flush. Run fresh media for about a minute before your first bath.
- Leaving the strap loose. Tighten it until the filter sits snug on the spout so all the water goes through the cartridge.
- Forgetting the cartridge. Past 3 to 6 months it has done its job. Subscribe and Save takes care of it.
- Expecting softer hard water. A bath filter reduces chlorine, chloramine, sediment and rust. It is not a water softener.
- Filtering the bath but not the shower. If you shower more than you bath, add Shower Mate or Shower Max so the whole bathroom matches.
Bath Tap Filter FAQ
What is a bath tap filter?
A bath tap filter is a small filter that attaches to your bath spout and cleans the water on its way into the tub. HolyH₂O Bath Mate uses KDF-55 and catalytic carbon to reduce chlorine (by up to 99%) and chloramine, plus sediment and rust, as the bath fills.
Will a bath tap filter fit my bath tap?
Bath Mate fits most standard bath taps. An adjustable strap tightens around the spout for a snug fit. If your bath fills from a handheld shower rather than a spout, filter the shower instead with Shower Mate. Not sure? Email a photo of your tap to hi@holyh2o.com.au and we will tell you.
Do I need a plumber or tools to fit a bath tap filter?
No. Bath Mate clips on with an adjustable strap, so there are no tools, no plumber and no permanent changes. That also makes it renter friendly, and you can take it with you when you move.
Does a bath tap filter work with chloramine?
Yes. Bath Mate pairs KDF-55 with catalytic carbon, an enhanced activated carbon built to tackle chloramine as well as chlorine, so it works whichever disinfectant your city uses.
How often should I replace the bath filter cartridge?
Every 3 to 6 months, depending on how often your household runs a bath. Subscribe and Save sends a fresh cartridge on schedule so you never have to remember.
Will a bath tap filter soften hard water?
No. A bath tap filter targets chlorine, chloramine, sediment and rust. It is not a water softener, so it will not remove the calcium and magnesium that make water hard.
Is a bath tap filter the same as a shower filter?
They use the same media but fit different places. Bath Mate straps onto your bath spout and filters the tub as it fills, while Shower Mate and Shower Max fit your shower arm. Many homes use both so the whole bathroom gets filtered water.
