PureRain™ — 6" Filtered Rainfall Shower Head for Hard Water
🚿 6″ rainfall coverage at full 2.5 GPM — a proper shower, filtered
💧 4-stage in-head filtration helps reduce chlorine, heavy metals & sediment
📦 Full Year Kit = head + 4 cartridges — under £5/month, no subscription ever
The proof is already hanging in your bathroom.
Those white-crusted nozzles on your current shower head? That’s what your water deposits on everything it touches — your hair and skin included. Around 60% of England showers in hard water, and every wash leaves an invisible film of chlorine and mineral deposits that no shampoo removes, because the next shower puts it straight back.
Hair that won’t behave
Dull, dry, frizzy no matter what you buy — and colour that turns brassy weeks early. The mineral film lifts the hair’s cuticle, so light stops bouncing off it.
The product graveyard
Clarifying shampoos, masks, oils, the £40 conditioner — a shelf of fixes that treat the symptom for a day. £30–60 a month, and the cause is still coming out of the shower head.
A shower head past its best
Crusted nozzles, a jet that sprays sideways, another descale with vinegar every month. You were going to replace it anyway — the only question is with what.
One swap, two upgrades: a proper rainfall shower — and filtered water
PureRain isn’t a gadget you bolt onto your shower — it is the shower. A polished-chrome 6″ rainfall face with wide, full-body coverage and soft silicone nozzles that shrug off limescale with a wipe of your thumb.
The filtration lives inside the head itself: nothing added to the column, no boxy attachment, no extra 10 cm. Just one clean object on the wall arm — doing quietly what £160-a-year subscription brands charge you monthly for.
The shower head you were going to buy anyway — with the upgrade your water actually needs.
4 filtration stages, hidden inside the head
Every drop crosses four layers between the pipe and your skin. The core stage, KDF-55, is a copper-zinc alloy from industrial water treatment — independently lab-tested to help reduce chlorine by up to 98%. And because hot showers are where cheap carbon filters give up, stage two is calcium sulfite: it keeps working at shower temperature.
KDF-55 — the chlorine stage
Copper-zinc alloy converts free chlorine on contact through an oxidation-reduction reaction. It’s the difference between a serious filter and a shower gadget.
Calcium sulfite — the hot-water stage
Handles chlorine and chloramines even in hot water, where carbon alone fades. This is the stage most cheap filtered heads skip — and why they stop working by week three.
Carbon + sediment mesh — the polish
Coconut-shell activated carbon helps reduce odours and trace impurities; a stainless mesh catches rust and grit from old pipework before it reaches your skin.
Judge it as a shower first. It wins there too.
The #1 fear with filtered shower heads is a weak, strangled jet — and with the cheap ones, it’s justified. PureRain’s cartridge is dimensioned for the full 2.5 GPM flow: four thin stages in series instead of one dense plug, so water moves through fast while still making contact with every layer.
The 6″ face gives wide rainfall coverage, and the anti-limescale silicone nozzles keep the spray pattern straight for years — no more jets firing sideways.
Full filtration. Full pressure. Pick both.
The full year, sorted — £54.95. No subscription.
The beauty brands got one thing right: filtering your shower works. Then they attached a subscription to it. Run the first-year numbers:
That’s under £5 a month — less than one clarifying shampoo — with every cartridge already in the cupboard. No account, no auto-renew, nothing to cancel. A water filter isn’t a lipstick; it shouldn’t bill you monthly.
Fitted in 2 minutes. And you always know when to change the cartridge.
Unscrew your old head, hand-tighten PureRain onto the wall arm. PTFE tape and spare washers are in the box; the standard ½″ thread fits virtually every UK bathroom. Renting? Nothing touches the plumbing — it unscrews in seconds and moves flats with you.
Other brands leave you guessing when the filter is spent. We keep it simple: one cartridge every 3 months (~3,000 gallons), and a reminder card in the box to stick on the calendar. Unscrew the face ring, drop the new one in, done.
The Full Year Kit has all four cartridges waiting — the whole year, one delivery.
What it does — and what it honestly doesn’t
The filtered-shower-head market is full of claims that don’t survive contact with chemistry. Here’s where we stand, in writing:
✅ What it does
- Helps reduce chlorine via KDF-55 + calcium sulfite — lab-tested, up to 98%
- Helps reduce heavy metals, rust and sediment from old pipework
- Helps reduce mineral build-up on hair and skin — many users notice softer-feeling hair in 2–4 weeks
- Delivers a genuinely better shower — 6″ rainfall coverage at full 2.5 GPM
- Installs in ~2 minutes, fully reversible — renter-safe
❌ What it doesn’t
- It does not soften water — calcium and magnesium stay dissolved; no shower head removes them, whatever the listing says. Only a £1,500 ion-exchange softener does that
- It’s not a medical device — it won’t treat eczema or any skin condition; it just makes the water kinder
- Results build over weeks of showers — it’s not an overnight transformation
- Cartridges aren’t forever — plan on a swap roughly every 3 months (hence the Full Year Kit)
If a shower head promises to “remove limescale” or “soften water”, it’s marketing, not chemistry. We’d rather tell you that here than have you find out in a review. 100 days to feel the difference — or a full refund.

Frequently Asked Questions
Will it fit my shower arm?
Yes, almost certainly — the standard ½″ thread (G1/2, BSP, NPT) fits virtually every UK wall arm. PureRain replaces your existing fixed shower head; it hand-tightens on in about 2 minutes with the included PTFE tape. If yours somehow doesn’t fit, send it back within 100 days for a full refund.
Will it reduce my water pressure?
This is the fear that keeps people on unfiltered water — and with cheap dense-block filters it’s real. PureRain’s cartridge is dimensioned for the full 2.5 GPM flow: four thin stages in series inside a high-flow head, so there’s no noticeable drop for typical UK showers. If you disagree once it’s fitted, the 100-day guarantee covers exactly that.
Does it soften water / remove limescale?
Honest answer: no shower head does — calcium and magnesium stay dissolved in the water. What PureRain does is help reduce chlorine, heavy metals, sediment and the mineral build-up that deposits on hair and skin. That deposit — not the dissolved minerals — is what makes hair dull and skin tight.
How long does a cartridge last, and how do I know when to change it?
Around 3 months of daily showers (~3,000 gallons) for a typical household — a bit less in very hard water or big families. No guessing games: the rule is simply every 3 months, and there’s a reminder card in the box. The Full Year Kit ships with 4 cartridges — the whole year, under £5/month, no subscription.
When will I notice a difference?
Most people notice water that feels “silkier” within days, and softer-feeling hair and less tight skin over 2–4 weeks of showers — the build-up already on your hair has to grow out or wash out. It’s a curve, not a switch. Give it a month; you have 100 days.
What’s the difference between PureRain and PureShower?
PureRain is a complete 6″ rainfall shower head with the filter built in — for fixed, wall-mounted showers, replacing your existing head. PureShower is a compact inline filter that fits between the hose and a handheld shower head. Same filtration philosophy, different bathrooms: fixed head → PureRain; handheld → PureShower.
