The shower filter for hair that turned to straw.
VATNARA Shower Filter
Pre-Contact Filtration: the chlorine comes out of every drop before it touches hair or skin. Nothing that goes on afterward can do what taking it out first does.
A drop test in every box — see it work yourself
$129
Hair like straw no matter what you put on it? The cause runs during the shower — this sits in front of it.
Takes the chlorine out of the water before it touches your hair. Adds nothing.
The brush goes through again — no velcro, no straw by noon.
Drop test in the box: tap water turns yellow, filtered stays clear. See it tonight.
Screws on by hand in five minutes. Standard ½-inch NPT thread, off again when you move.
60 days to decide — money back, and you keep the filter.

Does it actually work — how would I know?+
You check it yourself. The box has two glasses and a reagent: three drops in tap water turn yellow, three drops in filtered water stay clear. Same evening, no lab needed. And below you'll find the lab report for this exact model.
Will it fit my shower?+
US shower arms use a standard ½-inch NPT thread. If your shower head unscrews by hand, the filter goes between the arm and the head. Six shower types are in the fit guide — ceiling rainfall is the one to check.
What happens in month four — and if I cancel?+
A fresh cartridge arrives every four months for $29. Five days before, you get an email: skip it, move it, or cancel — one click, no call, no minimum term. Cancel after the first one and you still keep the filter.
How long does it take to install?+
About five minutes, no tools, no plumber. Unscrew the head, twist the filter on, head back on top. It comes off again when you move out.
What's in the box?+
The filter with the first cartridge, the drop test (two glasses, reagent), the switch card for the first two weeks, thread seal tape.

In their words
The thing that sent you looking.
Same water, different complaints. Tap yours — the why comes right after.
Why it feels like straw no matter what goes on it.
The filter sits in front of the showerhead and takes the chlorine out before it touches anything.
Before
Week 6
It looked like I'd given up.
That photo my sister took from behind — I hated it. Straw. Like I didn't take care of myself, when I was trying so hard. Six weeks with the filter and the ends actually move again. I keep touching them.
Why it keeps happening
It's the water. Not you.
Masks, conditioner, oils, the forty-dollar bottle — all of it goes on after the water. And the next morning, eight more minutes of water run over the same hair.
Tap water carries chlorine so it is safe. Chlorine is a disinfectant, which also makes it a solvent: it lifts the thin layer of oil that lets strands slide past each other. Without that layer, hair catches. That is the “velcro”, the “straw”, the greasy-and-dry-at-once.
Inside: four stages, chlorine out before it touches your hair ⟨stages pending⟩
You've already run the test.
People have run this test on themselves for years without calling it one. Hair that turns soft on vacation. Hair that changed after a move. People who carry gallon jugs of distilled water into the shower. Take the water out of the equation and the problem changes. This filter sits in front of the showerhead and takes the chlorine out before it touches anything.
Tried a filter before and nothing happened?
This one you check yourself. Tonight.
Two glasses. Three drops. Yellow means chlorine — clear means it's gone.

What you are actually buying
The first morning the brush goes through.
Not the filter. The morning after it. A brush that goes through without catching, ends that don't feel like straw by noon — the thing everything else in the cabinet was bought for.

What changes
Your first four months.
What people notice, and when — with the photos they sent.
Day 1
The drop test, the same evening.
“Two glasses, three drops each. The tap one went yellow before I'd put the bottle down. The filtered one just… stayed water.”
Ana G.Sacramento, CA

Week 1
Nothing dramatic yet — and that's normal.
“Honestly? Week one I kept checking and couldn't tell. The card in the box said that would happen. The drop test was the only thing that had changed.”
Ana G.Sacramento, CA
Week 2
The comb goes through wet hair.
“I used to wrestle a comb through my hair after every shower. Second week I noticed I'd stopped bracing for it. That was the moment.”
Marisol T.Fresno, CA
BeforeWeek 2
Week 3
The skin stops feeling tight.
“Every shower ended with the same race to the lotion. Somewhere in week three I walked out, got dressed, and only later noticed I'd skipped it. My face just felt like my face.”
Leila H.Phoenix, AZ
BeforeWeek 3
Week 6
The curls come back.
“My curls had turned into a fuzzy halo and I blamed my age. Six weeks in they clump again. Same products, same me — different water.”

Month 4
The cartridge tells you it's done.
“Pulled the old one out when the flow dropped — brown at the top, honestly a little gross. The new one was already in the cupboard. Two minutes.”

Looking back
The one they tell their friends to buy.
“I spent months reading about filters. My friend said: just get the one with the test in the box and stop reading. She was right.”

Watch it work
Five minutes. No plumber. No tools.
Twist your shower head off, twist VATNARA on, twist the head back. Watch both jobs before you buy.
1
Unscrew your existing shower head
Turn it anticlockwise by hand — most are hand-tight, no wrench needed. Keep the rubber washer that sits inside.
~1 min
2
Twist VATNARA onto the arm
Clockwise, finger-tight plus a quarter turn — don't over-tighten. Standard ½-inch thread, the same on almost every US shower ⟨SPEC⟩.
~1 min
3
Twist your shower head back on top
Onto the filter's outlet end. Run the water for 30 seconds to flush — the first burst can look a little cloudy while the media settles ⟨SPEC⟩.
~2 min
1
Twist the body open
The filter stays on the arm. Hold the top, turn the bottom half anticlockwise — it comes off by hand ⟨SPEC⟩.
~10 sec
2
Old cartridge out, new one in
It drops out. The new one goes in the same way up — there is only one way it fits.
~5 sec
3
Twist closed and flush
Turn the bottom half back on until it stops. Run the water for 30 seconds before you step in.
~30 sec
Shower arm sitting close to the wall? ⟨Adapter — question to B⟩ — check the fit guide below.
Will it fit?
One thread fits almost every US shower.
US shower arms use a standard ½-inch NPT thread. If your shower head unscrews, the filter goes between the arm and the head ⟨SPEC: NPT von B bestätigen⟩. Tap yours.
Classic
Fits. Unscrew the head, twist the filter on, head back on top.
Arm sits close to the wall? ⟨Adapter — Frage an B⟩. Not sure? Send a photo to support@vatnara.com — we confirm before you buy. Wrong guess? Sixty days, one email, money back — and the filter stays.
Buy this if
Your hair feels like straw no matter what goes on it.
Your skin feels tight after every shower.
It changed after a move — or it's better every time you travel.
You'd rather fix the water once than buy chelating shampoo every other week.
Don't buy this if
You want a whole-house system. This is for one shower.
You're looking for fluoride removal. This filter isn't built for it.
Your hair is suddenly falling out. That is a question for a doctor first.
How it compares.
Honest rows only. Where a typical filter does it too, it says so.

No more velcro
After conditioning my hair used to feel like velcro — no slip at all, impossible to brush. I'd started to feel like I looked like I didn't take care of myself. That's the part I don't miss.
Maya R. · Salt Lake City, UT · 7 weeks in

Two years of gallon jugs
I was the person carrying distilled water into the shower. Every wash. I wanted something that came close without the hauling, and I rent, so no softener. It screwed on by hand. The jugs are gone.
Jess M. · Austin, TX · 9 weeks in

Moved to Denver, hair turned to straw
Same shampoo, same routine, new apartment — and my hair started feeling like straw. At home over Christmas it was soft again, which is when it clicked that it was the water. The drop test the first night: tap yellow, filtered clear.
Lena K. · Denver, CO · 6 weeks in

My clarifying shampoo habit cost more
I was buying a $20 chelating shampoo every other week because the buildup kept coming back. I did the math on a year of that. Still use my conditioner — it just isn't fighting the water anymore.
Priya S. · Phoenix, AZ · 8 weeks in

Pressure drops a bit as the cartridge fills
Honest review: the flow is a little lower than my old shower head and drops more before the cartridge is due. They say that on the page, so no surprise. Worth it for me.
Dana R. · Las Vegas, NV · 14 weeks in

My last filter was “spa beads”
My last filter had mystery beads and did nothing I could notice. This one came with a test I could run myself, which is honestly why I kept it past the first week.

Questions
Does the water pressure change?+
A little — and it drops further as the cartridge fills. The lab measured 8.0 litres a minute new and 5.2 at 7,500 litres ⟨SGS⟩. That drop is the signal to swap the cartridge.
Does it remove fluoride?+
No. It isn't built for fluoride, and we would rather say that here than in a return request.
How does the cartridge plan work?+
You pay $129 today for the filter, the first cartridge and the drop test. Every four months we send one cartridge for $29. Five days before each shipment you get an email — skip it, move it, change the interval to three or six months, or cancel. One click, no call, no minimum term.
What if I cancel after the first cartridge?+
Then you keep the filter, you paid $129 instead of $149, and you buy cartridges at $35 whenever you want. We would rather you cancel than feel trapped — that is the one thing people hate about filter subscriptions, and we read every one of those reviews.
What if it does nothing for me?+
Sixty days. Write us one line and the money comes back. You don't send the filter back — a used filter can't be resold anyway.
Not answered here? Email us or call ⟨phone⟩. Monday to Friday, 9am – 5pm ET.
