UK tap water is treated with chlorine — the same chemical that dries your skin and strips your hair. This removes it at the showerhead. Stainless steel, installs in 2 minutes.. KDF-55 + activated carbon shower filter. Made from KDF-55, Activated Carbon, Calcium Sulfite, Stainless Steel Housing. Free from Plastic housing, Single-stage carbon-only filters, Vitamin C cartridges, Chrome-plated brass fittings, PVC hoses and gaskets. Chlorine and chloramine in shower water are absorbed through the skin and inhaled as steam. A 10-minute shower exposes you to as much chlorine as drinking 2 litres of the same water — via dermal and inhalation routes that bypass liver detoxification. 1 verified customer reviews, 5/5 average. £56.00 with free UK shipping.

How We Compare
Eso World vs. typical products.
| Eso World | Typical | |
|---|---|---|
| Housing | Stainless steel | Plastic |
| Filter stages | 3 (KDF-55 + carbon + calcium sulfite) | 1–2 (carbon only or vitamin C) |
| Hot water effective | Yes — KDF works at shower temperature | Carbon effectiveness drops in hot water |
| Chloramine removal | Yes — calcium sulfite stage | Most don’t address chloramine |
| Cartridge life | 6–12 months | 2–3 months |
Comparison summary: Housing: Eso World uses Stainless steel, typical alternatives use Plastic. Filter stages: Eso World uses 3 (KDF-55 + carbon + calcium sulfite), typical alternatives use 1–2 (carbon only or vitamin C). Hot water effective: Eso World uses Yes — KDF works at shower temperature, typical alternatives use Carbon effectiveness drops in hot water. Chloramine removal: Eso World uses Yes — calcium sulfite stage, typical alternatives use Most don’t address chloramine. Cartridge life: Eso World uses 6–12 months, typical alternatives use 2–3 months.
How to Use
Getting started.
1
Unscrew your shower head
Standard ½" thread. No tools needed for most showers.
2
Screw the filter onto the shower arm
Hand-tight is fine. The rubber washers (included) seal the connection.
3
Screw the shower head onto the filter
Your shower head goes on the other end. The filter sits between the arm and the head.
4
Run the shower for 30 seconds
Flush the cartridge before first use. Water may look slightly grey for the first few seconds — that’s carbon dust, it’s harmless.
What to Expect
The first 6–12 months weeks.
Day 1
Chlorine smell gone
The most immediate change. If you could smell chlorine in your shower before, it’s gone. The water feels different on your skin almost immediately.
1–2
Hair and skin start to change
Less dryness after showering. Hair feels softer, less brittle. Skin doesn’t feel tight. If you have colour-treated hair, it holds colour longer without chlorine stripping it.
4–8
Noticeable difference
People with eczema, psoriasis, or dry skin conditions often report improvement around this point. Less itching, less flaking. Not a cure, but removing chlorine helps.
6–12 months
Replace the cartridge
When the chlorine smell returns or flow rate drops noticeably, the cartridge is spent. Unscrew, swap, done.
Questions & Answers
8 questions answered.
Yes — if they use the right media. KDF-55 removes chlorine through electrochemical redox, which works at shower temperatures where activated carbon’s effectiveness drops. A 10-minute shower exposes you to as much chlorine as drinking 2 litres of the same water (Weisel & Chen, 1994) — via skin absorption and steam inhalation that bypass liver detoxification.
Three things matter: filter media (KDF-55 outperforms carbon alone in hot water), housing material (stainless steel doesn’t degrade in steam like plastic), and fitting compatibility (standard ½″ universal). Most shower filters sold in the UK use plastic housings with carbon-only cartridges — carbon’s chlorine adsorption drops significantly above 40°C.
Unscrew your shower head. Screw on the filter. Screw the shower head onto the filter. Standard ½″ universal fitting — 2 minutes, no tools, no plumber.
Every 6–12 months depending on water hardness and usage. If you notice reduced flow or the chlorine smell returning, it’s time.
Minimal. The three-stage filter is designed for shower flow rates. Most people don’t notice a difference.
KDF-55 is a copper-zinc alloy that removes chlorine and heavy metals through electrochemical oxidation-reduction. Unlike carbon, it maintains performance at hot water temperatures (40–50°C). Combined KDF + carbon outperforms either alone (Heeb et al., 2002).
No. No shower filter removes fluoride — that requires reverse osmosis or distillation. This filter targets chlorine, chloramine, and heavy metals — the compounds that dry skin, strip hair, and trigger eczema.
Most shower filters use ABS or polypropylene plastic housings. Hot steam degrades plastic over months, leaching trace plasticizers into the water stream hitting your skin. Stainless steel 304 is inert at shower temperatures.

Risk Analysis
Dermal absorption and inhalation of chloroform during a standard 10-minute shower produce blood plasma concentrations equivalent to drinking two litres of the same water. The combined dermal and respiratory exposure route bypasses first-pass liver metabolism entirely — a fraction of shower chlorine and chloroform byproducts enters the bloodstream directly.
Brown HS, Bishop DR, Rowan CA (1984)
American Journal of Public Health
Adult skin absorption of volatile chlorinated compounds increases substantially at shower temperatures (37–45°C) compared to cooler contact. Hot water dilates dermal vasculature and increases transdermal permeability. For volatile organic disinfection byproducts, the shower delivers significantly greater total dose than drinking the same water cold.
Heeb NV, Dolezal IS, Bhattacharjee S, Zünd T, Ander H (2002)
Water Research
KDF-55 media (copper-zinc alloy) removes free chlorine and chloramine from water through electrochemical redox reactions rather than physical adsorption. Unlike carbon, which saturates over time and loses effectiveness, KDF maintains performance at hot water temperatures where activated carbon’s adsorption capacity drops. Combined KDF + carbon filtration outperforms either medium alone in shower applications.
Villanueva CM, Cantor KP, Grimalt JO, Malats N, Silverman D, Tardon A, Garcia-Closas R, Serra C, Carrato A, Castaño-Vinyals G (2007)
American Journal of Epidemiology
Long-term exposure to chlorination byproducts (trihalomethanes) in drinking and bathing water was associated with increased bladder cancer risk. The exposure routes included ingestion, inhalation, and dermal absorption — with showering and bathing contributing a significant proportion of total THM exposure due to the vaporisation of volatile compounds at warm water temperatures.
Nuckols JR, Ashley DL, Lyu C, Gordon SM, Hinckley AF, Singer P (2005)
Environmental Health Perspectives
Blood concentrations of trihalomethanes (THMs) — chlorine disinfection byproducts — increased measurably after showering, bathing, and swimming. The increase was primarily attributed to inhalation of volatilised THMs in steam and dermal absorption through warm, dilated skin. Showering for 10 minutes produced higher blood THM levels than drinking 1 litre of the same water.
