Unscrew your old shower head by hand, counterclockwise. Wrap the thread with the tape in the box. Screw this head on until it is hand tight. Run the water for 30 seconds to flush the cartridge. Fits every standard half inch shower arm. No tools, no drilling, nothing permanent. If you rent, put your old head back on the day you move out.
Warm water opens your pores, and that is the exact moment your skin meets chlorine, chloramines and whatever your pipes are shedding. Chlorine is a solvent. It dissolves fat. Your skin barrier is a fat layer. Skin that rebuilds that layer within hours is fine. Skin that does not get there before the next shower is why a cream worked for a week and then stopped. This removes the irritant before it reaches you.
No. This is a shower head with filtration built into the housing, not a puck you stack between the arm and your old head. Stacked filters cause the pressure drop people complain about. Most people say the spray feels slightly softer and more even.
You had the right idea and the wrong device. Almost every filter under forty dollars is single stage activated carbon. Carbon works on chlorine at cold temperatures and loses most of its effect at shower heat, usually within weeks, without any signal that it stopped. It also does nothing for chloramines or heavy metals.
Use it for 100 days. Run a full cartridge through it. If your skin is no calmer, email us and you get your money back. No form, no explanation, no original packaging.
In the water, not in a cream
Those four are why a $25 puck feels like nothing. We are not pasting another store’s survey on this page.
What is in your shower water
A solvent added to nearly all US tap water. It dissolves the lipid layer your barrier is made of, at exactly the moment your pores are open.
Chlorine bound to ammonia. More stable, harder to remove, completely untouched by cheap carbon filters.
Hard water minerals stop soap from rinsing away cleanly. What is left behind keeps working on your skin long after you have towelled off.
Leaching out of aging pipes on the way to your shower head. Nickel is a documented contact irritant for reactive skin.
Your acid mantle sits around pH 5. Hard, chlorinated water runs well above that and pushes it out of range every time.
The mechanism
A filter is only as good as what is packed inside it. These four were chosen for skin, not for hair, and each one handles something the others cannot. Every drop passes through all four before it reaches you.
Chlorine & chloramine
Neutralizes chlorine and chloramines at full shower temperature, where cheap carbon gives up within weeks. This is the medium almost no filter on the shelf includes.
Chloramine, fast
Ascorbic acid is the fastest thing there is at taking chloramine apart, and speed is the whole game in a shower, because the water is inside the cartridge for about a second.
Metals
A copper zinc medium that captures copper and nickel coming off aging supply lines, and keeps the carbon from turning into a bacterial bed inside the cartridge.
Polish
Takes out residual taste, odor and organic compounds the other three leave behind. Coconut shell has a finer pore structure than the coal carbon in budget cartridges.
How we compare
What to expect
The shower itself feels different. Less of the tight, squeaking feeling when you towel off.
The post-shower flare gets smaller. The window between stepping out and reaching for the cream stops being the worst part of the morning.
Your moisturizer starts holding. Nothing about the cream changed. It is finally landing on a barrier that was not stripped five minutes earlier.
You stop thinking about it as often. Fewer mornings that start with checking your arm.
Reviews
The page we cloned fills this block with written testimonials. Those are not our customers. This slot stays empty until we have our own.
Install it, shower with it, run a full cartridge through it. If your skin is no calmer at the end of 100 days, email us and we send your money back. No form, no explanation, no original packaging required.
FAQ
If your shower head screws onto an arm coming out of the wall, yes. That is a standard half inch connection and almost every North American home and apartment uses it. It does not fit ceiling mounted rain heads or handheld hose setups without an adapter.
About every 3 months, sooner with several people showering daily or unusually hard water. Your first one is included. Replacements you order when you want one.
No, and anyone telling you a shower head softens water is not being straight with you. Softening needs ion exchange and a tank. This reduces chlorine, chloramines, heavy metals and particles. For reactive skin those are the irritants that matter. The chlorine is the offender, not the minerals.
It filters the water for everyone using that shower. Nothing is applied to skin and there is nothing to dose. If a child is under the care of a dermatologist, this does not replace anything they have prescribed.
No. This is the most common complaint in the category and we are not doing it. You buy the filter once and reorder cartridges when you want them. Nothing auto renews.
