Copper-Zinc Redox Media
The media class used in certified shower filters to reduce free chlorine and inhibit bacteria growth inside the cartridge — so the filter stays cleaner between refills.

MEELA is the Norwegian-engineered shower filter built for Britain's hard, chlorinated water — it neutralises the calcium that dries your skin and dulls your hair, before the water touches you.



What hard water does — the research
"Water hardness, measured in mg/L of calcium carbonate. Oslo's water is around 35. London and the South East run as high as 338 — up to 10× harder — and around 60% of UK homes sit on hard water."
Hard-water calcium binds with soap into an invisible film that's left on your skin after rinsing.
Washing in hard water increases surfactant deposits and disturbs the skin barrier (Journal of Investigative Dermatology, 2018).
Mineral deposits build up on the hair cuticle — the flat, dull, hard-to-style feeling that disappears on holiday.
Chlorine keeps water safe in the pipes — your skin just doesn't need it in the shower.
The same calcium film that clings to your skin is what mineralises onto glass and grout between cleans.
MEELA reduces what water leaves on your skin and hair. It is not a treatment for any medical condition. Research also links hard-water areas to higher eczema prevalence (Journal of Allergy and Clinical Immunology, 2016).
Oslo vs London

A Norwegian standard
In Norway, most drinking water is sourced from protected lakes and disinfected primarily with UV light, with only minimal chlorine. The result is naturally soft, low-mineral water — the kind you drink straight from the tap without a second thought.
It's so quiet you don't notice it. Until you move somewhere else.
MEELA was built around one idea — that what touches your body every day should be as close as possible to the standard we left at home. The shower filter is that promise, applied to water.
The filter media
Chlorine · Bacteria control
Copper-Zinc Redox Media
The media class used in certified shower filters to reduce free chlorine and inhibit bacteria growth inside the cartridge — so the filter stays cleaner between refills.
Residual chlorine · Odour
Activated Carbon, Coconut Shell
Adsorbs residual chlorine and impurities — the workhorse of shower filtration. Coconut-shell carbon is denser and more porous than coal-based carbon, so it does more work per cartridge.
Polishing stage
Polishing Media
A polishing layer that targets dissolved impurities as water passes through — the last pass before the water reaches the hard-water stage.
Hard-water calcium
Template-Assisted Crystallisation
The hard-water stage. TAC doesn't remove calcium — it crystallises it into microscopic particles that rinse away instead of sticking to your skin, hair and shower glass. In independent tests, TAC technology prevents up to 99% of scale.¹

The Science
Hard water doesn't damage your skin because calcium is "bad" for you. It damages your skin because dissolved calcium ions bind to soap, oils, and skin proteins, leaving a microscopic film that dehydrates the barrier and clings to hair cuticles.
A whole-house softener removes the calcium by swapping it for sodium. Effective, but expensive, salt-heavy, and discharges brine into the water supply. Not how we'd choose to drink water.
TAC media solves the same problem differently. As water passes through it, calcium and magnesium ions nucleate onto microscopic templates and form stable, suspended micro-crystals. The calcium is still there — but it's been physically restructured into a form that can't deposit on surfaces.
You keep the mineral in your water. You lose the residue on your skin.

Installation
Twist counter-clockwise. Most heads come off by hand. A wrench helps if it's been on a while.
PTFE tape included in the box. One layer around the shower arm threads stops drips.
Hand-tight, then a quarter turn with the wrench. Fits standard UK ½-inch (G1/2 BSP) shower fittings. 10 L/min flow — matched to standard UK showerheads, so your pressure doesn't drop.
The 60-day promise
60-day money-back guarantee — even used. Four working media, each chosen for what UK tap water actually contains: KDF-55 for chlorine and bacteria control, coconut-shell activated carbon for residual chlorine, ion-exchange resin as a polishing layer, and TAC media to neutralise hard-water calcium. A fifth stage (Biochar, sourced from CaptureBank) rolls out in 2026 — subscribers get the upgrade free.
Common questions
A shower filter isn't a water softener. MEELA's TAC media crystallises dissolved calcium into microscopic particles that rinse away instead of sticking to skin, hair or shower glass. In independent tests, TAC technology prevents up to 99% of scale.¹ You'll still need to clean any existing visible scale once — but it won't keep rebuilding the way it did.
Most shower filters use one or two media, typically KDF and a sulphite, focused on chlorine. MEELA is designed specifically for UK water: KDF-55 plus coconut-shell activated carbon on chlorine, an ion-exchange resin as a polishing layer, and — the key one — TAC media to neutralise hard-water calcium. It's designed for what actually comes out of UK taps.
No. MEELA is engineered around a 10 L/min flow — matched to a standard UK showerhead — so the media doesn't restrict flow, even on a combi boiler.
The active media has a finite capacity. Around 90 days of typical UK shower use, it's time for a fresh cartridge. The subscription sends one automatically at £29. Pause, skip or cancel any time from your account.
