The Replacement Filter That Keeps Your Colour Safe — Every 90 Days.

★★★★★★★★★★ 4.7/5 · 87 Reviews

The Luminous Restoration Cartridge

Your showerhead removes the chlorine and minerals destroying your colour. But only while the filter media is active. At 90 days, the filter media is used up — and your shower returns to what it was before.

The best filter that exists.

We engineered the Luminous cartridge specifically around the two ways chemicals destroy professional hair treatments — not water in general.

Tested to perform — no pressure drop
Targets chloramine — the disinfectant most major Australian councils use that standard filters miss
Removes heavy metals — including the iron that turns blonde orange
Vitamin C & E infusion — antioxidants in every shower
Swaps in under 2 minutes — no tools, no plumber
Lasts exactly 90 days — ships automatically so you never run out
Less than $0.45 a day to protect a $400–$1,500 appointment

Forget when to change that filter?
We've got you.

Your filter works hard for a full 90 days. After that, it's simply ready for a fresh one. The subscription handles the timing for you — a new cartridge arrives right when it's due, so your colour protection never has a gap.

No need to guess. No calendar reminders. A fresh cartridge arrives at the 90-day mark, two minutes to swap, and protection never lapses.

Built to Protect Your Colour.

Each layer doing a specific job. Here's exactly what's inside your cartridge — and why it's there.

Stage 1–3

Pre-Filtration Mesh & PP Cotton

Catches rust, dirt, and particles right at the start — so the rest of the filter stays clean and lasts the full 90 days.

Sediment Removal

Stage 4–5

Alkaline Ceramic Balls & Millstone

Softens the water and balances its pH so it's gentle on colour-treated hair. Also helps stop mineral buildup on the hair shaft.

pH Balancing · Mineral Softening

Stage 6

KDF-55 Redox Media

Turns chlorine into a harmless form and removes heavy metals like iron, lead, and copper. Iron is the main reason colour-treated hair goes orange and brassy.

Chlorine & Heavy Metal Removal

Stage 7–8

Microporous Ceramic & Vitamin C & E

Adds an extra filter pass to block bacteria, then infuses the water with Vitamin C and E. Vitamin C removes any leftover chemicals and adds nourishment to every shower.

Antioxidant Infusion

Stage 9

Coconut Activated Carbon

Soaks up chloramines, chemical smells, and other compounds — catching anything the earlier layers missed.

Chloramine & Odour Removal

Stage 10–12

Germanium, Calcium Sulfite & Magnetic Ceramic

Targets chloramine — the chemical most major Australian councils use that regular filters miss. The other materials further soften the water and reduce mineral buildup.

Chloramine Destruction · Mineral Softening

Stage 13–15

Post-Filtration Mesh & PP Cotton

A final pass to catch any loose particles. By the time water leaves the cartridge, it's clean, balanced, and free of the chemicals that fade your colour.

Final Filtration & Clean Output

Samantha Cusick London

"When you're dealing with hard water, it's not just colour fading a bit faster. Chlorine can cause everything from premature fading and brassiness to a rough, straw-like texture."

Samantha Cusick, Founder & OLAPLEX Ambassador

Paul Edmonds London

"Hard water affects hair colour because the hair is less shiny so the colour doesn't look as vibrant — and if the cuticle is more open, pigment escapes and the colour fades more quickly."

Marvyn Duche, Senior Colourist

Hair.com by L'Oréal

"All the minerals and heavy metals in hard water can cause your hair to become dry, brittle, brassy, and dull. Hard water will strip and fade your hue more quickly."

Nikki Lee, L'Oréal Colorist

Don't skip a replacement

I left mine in a bit past the 90 days, just hadn't gotten around to swapping it. I think that's when the brassiness started coming back, because a fresh one in and it settled again within a week. I let the subscription handle it now.

Took two minutes

Was half-expecting a fiddly mess. Old one out, new one in, done before the kettle boiled. Slides in one way so you can't get it wrong.

Does the job

Works fine and the cost per day is honestly less than my morning coffee, so no complaints there. Took me a bit longer than I expected to really notice a difference in my colour, but it got there.

Wish it lasted longer

Performs perfectly, no issues there. Only wish I reordered a bit less often, but I understand why it's timed the way it is. Happy overall.

Everything You Need to Know.

Will this fit my shower? +

Yes. The Luminous showerhead uses a standard G1/2 thread — the universal connection used in every Australian home. No adaptor, no tools required.

How do I replace the cartridge? +

Pull out the spent cartridge, slide the new one in — it only fits one way. The whole swap takes under 2 minutes and requires no tools.

Is this safe for coloured and chemically treated hair? +

Yes — completely. The filter only acts on what's in the water. It won't interfere with keratin, colour, bleach, or any other treatment. Removing chlorine and hard minerals actively protects those treatments.

Will this affect my water pressure? +

No. The Luminous cartridge is engineered for standard Australian shower pressure (40–80 PSI). Pressure drop is the #1 complaint about budget filters — we designed around it specifically.

Can I pause or cancel the subscription? +

Yes — at any time, with no penalty. Pause, skip, or cancel in under 60 seconds. No lock-in, no cancellation fee.

What's the difference between the one-time and subscription? +

The subscription ($39) auto-ships every 90 days and saves you 22% versus one-time ($50). Both use the identical 15-stage media. The subscription also means you never have to remember to reorder.

I only got the showerhead recently. Do I need a replacement already? +

Not yet. Your first cartridge is included with the showerhead and lasts 90 days. Set up the subscription at checkout so the replacement arrives automatically.

Just Here to Learn?

The replacement cartridge only works with the Luminous Showerhead. If you don't have the system yet, start there — the showerhead comes with your first 90 days of filtration included.
