ACF
Activated carbon fibre
A high-surface-area medium designed to adsorb residual chlorine and help reduce unwanted odours, abnormal colour and selected organic contaminants in everyday shower water.
The system
What actually happens between the hose and your skin.
Senca is a filtration architecture with a beauty stage at the end. Below is every medium we use, what it is designed to do, and — just as importantly — what we do not claim it does.
The sequence
Filter. Refine. Infuse. Choose your flow.
Water passes through the stages in order. Each one prepares the water for the next.
01
Filter
Water enters through layered particulate media that captures sediment, rust, colloidal material and smaller particles before anything reaches your skin.
02
Refine
Activated carbon fibre adsorbs residual chlorine and selected organic contaminants — the stage that changes how the water smells and feels.
03
Infuse
A Vitamin C cartridge sits in the final stage. This is the beauty and wellness layer of the shower — a softer, more considered finish to the water.
04
Choose your flow
Select the mode that suits the moment: a full shower stream for everyday washing, or a finer mist for a gentler, more enveloping rinse.
Filtration architecture
Layered, in a fixed order.
A cartridge is not a single filter. It is a stack, and the order it is stacked in is the design.
In
Shower water
Sediment · rust · residual chlorine · selected impurities · dissolved minerals
Senca media stack
Particulate → carbon fibre → Vitamin C
Out
Refined shower water
Delivered through a finely perforated spray plate, in shower or mist mode
01
Particulate layers
Designed to capture sediment, rust, colloidal material and smaller particulate pollutants carried by ordinary shower water.
02
Activated carbon fibre
A high-surface-area medium designed to adsorb residual chlorine and help reduce unwanted odours, abnormal colour and selected organic contaminants.
03
Hard-water design
The architecture is built for hard-water homes, helping reduce the mineral residue and build-up that clogs a spray plate over time. Senca is not a water softener.
04
Vitamin C stage
The final stage. A Vitamin C formulation that gives the shower its sensory, beauty-led character.
Technology
Every medium, described honestly.
Manufacturer specifications describe what these materials are engineered to do. Until we hold independent testing of our own, that is exactly how we will describe them — as design intent, not as a measured result.
Multi-stage
Particulate filtration
Layered media designed to capture sediment, rust, fine particles and colloidal material before water reaches the spray plate — the groundwork every other stage depends on.
Ritual
Vitamin C
A Vitamin C formulation — typically Vitamin C concentrate with glycerine and aromatic components — positioned as the sensory, beauty-led finish to the shower rather than a clinical treatment.
Scale
Hard-water design
Filtration designed with hard-water environments in mind, helping reduce the mineral residue and build-up that dulls a spray plate over time. Senca is not a water softener.
Flow
Spray technology
A finely perforated spray plate with two selectable modes: a regular shower spray for everyday use, and a finer mist-style spray for a softer, more enveloping rinse.
The cartridge
One stack, replaced as a set.
Everything the system consumes lives in one cartridge assembly, so replacing it is a single job rather than a parts list.

Spray technology
Two modes, one plate.
A finely perforated spray plate produces a refined, comfortable flow. Switching modes changes the character of the water without changing the fitting.
Mode one
Shower
A regular, full shower stream for everyday washing and rinsing.
Mode two
Mist
A finer, softer spray — the more enveloping, spa-style end of the range.
Installation
Four steps, no tools, under a minute.
Senca threads onto the standard shower hose fitting. If your bathroom uses a non-standard connection, talk to us before you order.
01
Unthread
Remove your existing shower head from the hose by hand. Nothing else in the bathroom is touched.
02
Seat the washer
Drop the supplied sealing washer into the connector — it is what keeps the joint dry.
03
Thread on
Screw the Senca head onto the standard hose fitting and hand-tighten. No tools, no tape, no plumber.
04
Run it through
Let the shower run for thirty seconds before first use so the media settles and the flow evens out.
Replacement
Roughly every three months.
Filtration media and the Vitamin C component are consumables — they do their job by being used up. Replacing them on schedule is what keeps flow consistent and the system performing as designed.
- Twist off the used cartridge stack by hand
- Seat the new components in the same order
- Rinse through for thirty seconds before use
- Recycle the packaging — it is designed for it
Still wondering
Technical questions, answered.
Senca uses multi-stage filtration designed for everyday shower water. Particulate layers are designed to capture sediment, rust, fine particles and colloidal material, while activated carbon fibre is designed to adsorb residual chlorine and selected organic contaminants.
No. Senca is not a water softener. The system is designed with hard-water homes in mind and helps reduce the mineral residue that builds up inside a shower head, but softening your household water is a different process entirely and we do not claim it.
That is exactly the environment it is designed for. Filtration helps reduce the mineral residue and build-up that clogs a spray plate and makes water feel harsh, which is why flow stays more consistent and the shower feels gentler. It does not change the water supply to your home.
It is the beauty and wellness element of the system, positioned at the final stage. Vitamin C formulations typically contain Vitamin C concentrate together with glycerine and aromatic components. We present it as part of the shower ritual and sensory experience — not as a medical or clinical treatment.
A regular shower spray for everyday washing, and a finer mist-style spray for a softer, more enveloping rinse. You switch between them on the head itself.
No. The head threads onto a standard shower hose by hand, with a sealing washer supplied in the box. No tools and no plumber required.
