“Tried everything. Olaplex, K18, serums. Turns out it was the water. Three weeks in and my stylist noticed before I even told her.”

Sarah M.

★★★★★ Verified

14 May 2026

You have tried everything. Expensive shampoos, hair masks, supplements, even a dermatologist. And still, your hair feels dry and your skin feels tight after every shower.

That is not your fault. It is your water. Tap water contains chlorine, heavy metals, and limescale that strip your hair and skin every single day, undoing everything your products are trying to do.

Cleansii uses concentrated KDF-55 filtration to remove what damages your hair and skin at the source. No gimmicks, no greenwashing, no empty promises.

Try it for 30 days. If you don't feel a difference, send it back for a full refund. No questions, no hassle.

  • Softer, shinier hair from the first week
  • Smoother, hydrated skin that holds moisture
  • Less hair breakage and shedding
  • Your existing products finally work the way they should
  • Reduced scalp irritation and dryness
  • A simpler, cheaper routine over time
  • Confidence without overthinking angles and lighting

What to expect: Week 1, your water feels softer. Week 2 to 3, your hair feels different. Week 4 and beyond, visible results in shine and volume. Results may vary depending on your water area.

Each Cleansii filter cartridge lasts approximately 3 months of daily use. Our 15-stage filtration system combines KDF-55, Calcium Sulfite, and activated carbon in concentrated doses to effectively remove chlorine, heavy metals, and limescale.

Why Cleansii is different: Not all 15-stage filters are created equal. Many budget filters list 15 stages but use each material in such small amounts that none of them work effectively. Cleansii uses higher concentrations of the materials that actually matter for your hair and skin.

No hidden subscriptions. When you need a replacement, you order one. No auto-renewals, no surprise charges, no 5 emails to cancel something you never signed up for. Just reorder when you are ready.

Everything you need. Nothing you don't. Installs in 3 minutes, no tools, no plumber, no landlord permission needed.

  • 1 Cleansii filtered showerhead
  • 1 filter cartridge (already installed inside)
  • Universal adapter set (fits 99% of all standard showerheads)
  • Plumber's tape
  • Step-by-step installation guide

Fits your shower or your money back. If it doesn't connect to your setup, return it within 30 days for a full refund.

Before and after skin texture
S
Sophie, London

My skin texture was rough and bumpy for years. 3 weeks with Cleansii and it finally feels smooth again.

Before and after eczema on hands
L
Laura, Edinburgh

My eczema on my hands would flare up after every shower. Since filtering my water, the redness has calmed down so much.

Before and after hair thinning
E
Emma, Manchester

I was losing so much hair around my hairline. After 2 months, the shedding slowed down and I can see new growth.

Before and after skin redness
M
Madison, Austin

The redness and little breakouts on my cheeks wouldn't go away. Turns out it was the water. My skin is so much calmer now.

Before and after hair vitality
T
Tina, Liverpool

Even at my age, my hair feels thicker and has more body since switching to filtered water. Less flat at the roots.

Before and after dry scalp
Z
Zoe, Sydney

My scalp was always flaky and itchy. Tried every dandruff shampoo. Filtering the water was the only thing that fixed it.

Before and after frizzy hair
S
Sarah, Birmingham

The frizz was out of control. No serum or oil helped. After filtering my water, my hair is smooth and manageable.

Before and after dry curly hair
R
Rachel, Leeds

My curls were dry, brittle and lifeless. Now they have shine and bounce again. My stylist asked what I changed.

“I’ve spent hundreds on Olaplex, Kérastase, hair masks. Nothing lasted more than one wash. Installed this in my rental flat in 2 minutes. After two weeks my hairdresser asked what I changed. It was the water the whole time.”

“My skin used to feel so tight and dry after every shower. I thought it was just my skin type. Tried this after my friend recommended it. The tightness was gone from the first shower. My moisturiser actually works now.”

“I bought a cheap Amazon filter first. Total waste. This one actually works. I can feel the difference in the water. My colour-treated hair lasts so much longer between appointments now. Already sent the link to three friends.”

“I was sceptical because of Jolie’s whole situation. Did my research on Reddit and Trustpilot before buying. Cleansii had real reviews from real people. Installed it in my apartment. No tools, no landlord call. Just works.”

“My dermatologist couldn’t figure out why my eczema flared up after moving. Turns out: hard water. This filter reduced my flare-ups significantly. I use less cream now than I did before. Only 4 stars because delivery took 5 days.”

Why Cheap Filters Don’t Work

“I tried a shower filter before and it did nothing.” We hear this a lot. Here’s why ours is different.

science

KDF-55 Filtration Media

Cheap filters stuff 15 random materials in tiny amounts, too little of each to do anything. We use a concentrated dose of KDF-55, the gold standard for removing chlorine and heavy metals in hot water.

layers

15-Stage Deep Filtration

Each stage serves a purpose: KDF-55 for metals, Calcium Sulfite for chlorine/chloramines, Coconut Activated Carbon for chemicals, PP Cotton for sediment, and Stainless Steel Mesh for pressure.

Renter-Friendly in 3 Minutes

No plumber. No tools. No landlord permission. Twist on by hand, twist off when you move. Fits 99% of standard showerheads. UK, US, and Australian fittings included. Your deposit stays safe.

What To Expect

Real results take a little time. Here’s what our customers typically experience:

W1

Week 1: Your Water Feels Different

The water feels noticeably softer. The chlorine smell disappears. Your skin doesn’t feel as tight after showering. This is the filter working immediately.

W2

Week 2-3: Your Hair Starts Changing

Hair feels softer, less brittle. You notice less hair in the drain. Your conditioner seems to work better because there’s no chlorine undoing it.

W4

Week 4+: Visible, Lasting Difference

More volume, more shine, less frizz. Skin stays hydrated longer. Your morning routine gets simpler. And someone will ask what you changed. Guaranteed.

Results vary depending on your local water quality. Harder water areas may notice results faster.

You Got Questions, We Got Answers

Everything you need to know before you buy.

Yes. Cleansii fits 99% of standard shower connections (½ inch universal thread) in the UK, US, and Australia. No tools, no plumber, no landlord or strata permission needed. Twist off your old showerhead, twist on Cleansii. Takes under 3 minutes. When you move, twist it off and take it with you. Your deposit stays safe.
Most cheap filters use tiny amounts of many different materials, too little of each to actually do anything. We use concentrated KDF-55 media combined with Calcium Sulfite and Coconut Activated Carbon in a true 15-stage system. Each stage has enough filtration material to actually work, not just fill a spec sheet. That’s why the cheap Amazon filter felt like nothing, and this one feels different from the very first shower.
Absolutely not. This is a one-time purchase. When your filter needs replacing (every 2-3 months depending on water hardness), you can buy replacement filters whenever you want. No auto-renewals, no surprise charges, no hoops to jump through. We’ll send you a friendly reminder email 7 days before, that’s it. You’ll never be charged without your explicit permission.
Yes. Chlorine is one of the biggest reasons colour fades faster than it should. It strips the colour molecules from your hair with every shower. By removing 98.7% of chlorine from your water, your colour treatments hold significantly longer. Many customers report going from 8-week to 12-week touch-ups. That saves you hundreds per year in salon visits alone.
Each filter lasts approximately 2-3 months depending on your water hardness and shower frequency. You’ll notice the water starting to feel different when it’s time to change. Replacement takes about 30 seconds. Just twist the old cartridge out and the new one in. No tools needed.
If you live in an area with hard or chlorinated water (most cities in the UK, US, and Australia), yes. Chlorine strips your hair’s natural oils and destroys your skin’s moisture barrier. That tight, dry feeling after every shower is your water, not your skin type. Once you remove that from your daily shower, your existing products can actually do their job. Most customers notice softer water in week 1, hair changes in weeks 2-3, and visible improvements by week 4.
We offer a 30-Day Money-Back Guarantee on all showerheads. Use it for a full month, even after installation. If you are not satisfied, contact us at hello@cleansii.com with your order number. We process your full refund within 5 to 7 business days to your original payment method. No questions asked, no hoops. Return shipping is your responsibility for standard returns. If your product arrived damaged or defective, we cover return shipping and send a free replacement. Original packaging is preferred but not required. Please note: used replacement filter cartridges cannot be returned for hygiene reasons. Unused filters can be returned within 30 days.
Yes. We ship to the US, UK, EU (including the Netherlands, Germany, France, Belgium, Austria, Ireland, Spain, Italy, and more), Australia, Singapore, and many other countries worldwide. Delivery takes 7-12 business days depending on your location. We work with regional distribution hubs across Europe, North America, Asia-Pacific, and Southeast Asia so we can offer free shipping on every order without inflating the product price. No surprise customs charges, no hidden fees. We handle everything so you just wait for your doorbell.
No. Our high-density stainless steel mesh and optimised internal design actually maintain or even improve water pressure. Many customers report their shower feels stronger after installation because the mesh creates a more focused stream.
Three signs: 1) The chlorine smell disappears immediately. 2) The water feels physically softer on your skin from the very first shower. 3) After 2-4 weeks, your hair and skin start responding differently to your existing products. And if you open the used filter after 3 months, you’ll see exactly what was going into your hair. It’s brown and full of sediment.
