Real skin and hair concerns,
solved at the source.
Chlorine and chloramine strip the skin barrier that protects eczema-prone and sensitive skin. Each shower can trigger flares, itch, and redness. Removing 99.9% at the source — before water touches your skin — gives your barrier room to heal. Most users report calmer flares within two weeks.
Shop ShowerhandKeratosis pilaris and full-body dryness both worsen with hard water and chlorine. Minerals clog follicles; chlorine strips the lipids that hold moisture. Filtered water lets your body lotion, exfoliants, and creams actually work — instead of fighting your tap.
Shop ShowerheadChlorine fades color treatments up to 3x faster. Mineral buildup leaves hair flat, dull, and brittle. Scalp irritation, dandruff, and itch all trace back to your shower water. Filtered showers keep color vivid, scalp calm, and conditioner doing its job.
Shop ShowerheadWhat's In Your Water
The problem starts when the tap water touches your skin.
Skin That Feels Easily Triggered
For sensitive or eczema-prone skin, chlorine and chloramine can feel harsh. Your shower water may be one more daily exposure that leaves skin feeling tight, itchy, or bumpy.
Hair That Feels Dry & Sheds
Sediments and disinfectants can leave hair feeling dry, coated, and harder to detangle — making wash days feel rougher and breakage more noticeable.
Scalp That Feels Tight & Flaky
Your scalp is skin, too. Sediment buildup and disinfectants can leave it feeling dry, tight, or flaky after repeated showers.
The Buildup Your Filter Reveals
Rust, scale, and pipe particles can move through aging plumbing. Your filter helps reveal what clear water can carry.

I didn't expect much, but my face wasn't as tight after showers. Even my derm noticed it looked less irritated.

We put it on before bringing the baby home. Two weeks later the inside was brown, which was honestly kind of gross.
40 days
Chicago water always felt harsh, but seeing the filter after 40 days made it feel very real. My skin feels less dry too.

Wasn't totally sold at first. Then I opened it up after a couple weeks and yeah, it was not clean.
30 days
My hair still isn't perfect, but it stopped feeling like straw after every shower. That alone made it worth it.

I showed my roommate the old filter because it looked nasty. She literally bought one the same night.

I always thought our water was pretty good. Three weeks later the filter looked like that, so I guess not.

Atlanta water plus old apartment pipes is a bad combo. The filter color changed quick, which was a little unsettling.

My husband thought it was one of my random bathroom things. Then he saw the filter after a month and stopped joking.

The Science
Most shower filters stop working within weeks. Ours doesn't.
Carbon and KDF filters physically absorb contaminants — and saturate. Vitamin C neutralizes chlorine through a chemical reaction that doesn't degrade during use. That's why our removal rate is the same on Day 60 as it is on Day 1.
- Chemical neutralization — not physical absorption
- 99.9% removal from Day 1 through Day 60
- Same chemistry used in hospital burn units
Verified
We don't self-report. We get tested.
NSF/ANSI 42* certification costs $15,000-$30,000 and takes 6-12 months. Most shower filter brands skip it. We didn't.

What Changes
Benefits that build over time.
Results from a 22-participant study measuring skin and hair changes after switching to filtered water.
See clinical data →Softer water, immediately
99.9% of chlorine neutralized from your very first shower. Most people notice the water feels different right away.
Less dryness, less tightness
Without chlorine stripping natural oils daily, your skin starts retaining moisture again. 95% of users reported less dryness.
Hair and scalp improvement
Hair retains more natural oils. Less breakage, less frizz. Color-treated hair stays vibrant longer.
Full skin barrier recovery
Your skin's protective barrier — weakened by years of chlorine exposure — completes its natural renewal. Skincare products work better on healthy skin.
We're serious about facts. Ask away.
How is this different from other shower filters?
Three things: (1) Vitamin C chemistry instead of carbon/KDF — it doesn't degrade during use. (2) NSF/ANSI 42* certified — independently verified, not self-reported. (3) Built-in truth window — you can see what the filter captured. No other brand offers all three. See the full comparison.
How long does the filter last?
30-60 days depending on your water quality. Two signs it's time: the Vitamin C powder in the lower chamber is depleted, or you notice reduced water pressure. Replacement filters cost $0.17 per shower.
Will it reduce my water pressure?
No. The Vitamin C reaction happens on contact without creating flow resistance. Our micro-jet array (128-176 jets) actually optimizes the pressure feel. KDF and carbon filters reduce pressure by 20-40% because they're dense media that block flow.
Can a shower filter help with eczema?
Chlorine is a known eczema trigger — the AAD acknowledges this. Removing it eliminates one of the most common environmental irritants. Many customers with eczema report improvement, but eczema has multiple causes and a filter addresses only the water component. Read what the research says.
How do I install it?
Unscrew your existing showerhead, attach the filter, screw the showerhead back on. No tools, about 60 seconds. Everything you need comes in the box. Fits 99% of US showers (standard 1/2" NPT). See the installation guide.
Your first filter tells you everything.
The truth window shows you what's been in your water. One look is enough.
