★★★★★ “Now the brush goes through in one pass.” — Rae T., 3 weeks inShower routines · tap to watch
What people say
“The brush goes through.” 4.8 stars, 100+ reviews.
- ★★★★★The brush goes through
I used to get stuck halfway down and just yank. Now the brush goes through in one pass. That is the whole review.
Rae T. · Tampa, FL · 3 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 - ★★★★★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 - ★★★★★Good, not magic
It did not turn my hair into a commercial. What changed is that it stopped getting worse every wash, and the comb does not catch anymore. Four stars because I expected more in the first week and nothing happened.
Sam L. · Portland, OR · 11 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.

- Strands turn rough — the straw feelingHair that feels like yours again
- Your conditioner is gone by the next showerYour conditioner lasts until the next wash
- Skin feels tight and dry after every showerBy week 2–3, skin stops feeling tight
- Hard minerals crust the shower head and glassThe scale layer slows new crust
- Chlorine fades color and shine, wash after washColor and shine that stay
- Chlorine turns blonde and gray hair brassyColor that stays the color you paid for
- Your hair smells like a poolHair that smells like your shampoo
Proof on night 1 · in your own bathroom
The drop test comes in the box. Fill two glasses. One from the tap. One through the filter. Add 3 drops to each. The tap glass turns yellow. That yellow is chlorine. It runs over your hair every morning. The filtered glass stays clear. You see it with your own eyes — the same night.
Why the masks never win
Your mask works after the shower. The chlorine hits during it.
Your city adds chlorine to kill germs in the pipes. The EPA allows up to 4 mg per liter in tap water. The average US shower runs 7.8 minutes (Water Research Foundation). A mask puts oil back after the shower. The next shower strips it again. That's why the straw keeps coming back.
$187 a year is about 50¢ a day. Less than one clarifying shampoo a month.
Inside the cartridge
7 layers. One job: chlorine out before it touches you.
- 1 · SedimentCatches rust flakes and grit from old pipes
- 2 · KDF-55Reduces heavy metals like lead
- 3 · Calcium sulfiteThe main layer. Takes out the chlorine.
- 4 · Vitamin CNeutralizes chlorine on contact
- 5 · Carbon fiberCuts the pool smell
- 6 · Scale layerResin grabs hardness minerals while fresh. The inhibitor slows new limescale on head, glass and tiles.
- 7 · Lemon beadsA light, fresh scent in the steam
One cartridge lasts about 4 months for one person. Then you swap in a new one: $29 on the plan.

What dermatologists say
It's not just you. Skin doctors see it too.
“If your skin feels excessively dry and itchy after showering, it might be due to the chlorine or hard water minerals.”
Dr. Brandon Kirschboard-certified dermatologist · quoted in HuffPost“Chlorine in particular can cause colored hair to fade faster.”
Dr. Brandon Kirschboard-certified dermatologist · quoted in HuffPost“If you're consistently dealing with dryness, dullness or scalp irritation, reducing that exposure may make a noticeable difference.”

Questions
Does it soften hard water?
Yes. An ion-exchange resin layer pulls calcium and magnesium out of your shower water — strongest while the cartridge is fresh. A scale-inhibitor layer stops new limescale on your shower head and glass for all 4 months. And it takes out the chlorine — the part that makes hair feel like straw.
Will it fit my shower?
US shower arms use a standard ½-inch NPT thread. If your head unscrews by hand, the filter goes between arm and head. Ceiling rainfall: email us before ordering.
How does the plan work?
$129 today for the filter, first cartridge and drop test. Every 4 months one cartridge for $29 instead of $35. Year one: $187 — about 50¢ a day. You get an email 5 days before each shipment. Skip, move or cancel in one click. No minimum term.
Does the water pressure change?
A little, and more as the cartridge fills. That drop is your signal to swap it.
How do I know there's chlorine in my water?
Two ways. Search "[your city] water quality report" — every US utility publishes one each year and lists its chlorine level. Or skip the reading: the drop test in the box shows it the first night. Yellow means chlorine.
When will I notice a difference?
Night 1: the drop test shows the chlorine is gone. Day 7: hair stops feeling like straw. Week 2–3: skin stops feeling tight. Week 6: the curls come back. You have 60 days to decide.
How long does one cartridge last?
About 4 months for one person. Then swap it. On the plan, the next one arrives on time for $29.
Does it remove fluoride?
No. It isn't built for fluoride — better we say it here than in a return request.
When does it arrive?
Free US shipping. Most orders arrive in 3–4 business days.
Every shower you wait: 7.8 more minutes of chlorine.
