HOW THE FILTER WORKS
+Not all filters are created equal.
Shower Theory's multi-stage filtration system removes up to 99% of harmful contaminants like chlorine and heavy metals — delivering cleaner, healthier water for your skin and hair.
Activated Carbon Filter
Removes 99% of chlorine to stop dryness and irritation.
PP Cotton Filter
Catches rust, sediment, and debris for crystal-clear water.
Mineral Stone Filter

When to change filter?
Change filter once it turns brown. On average our users report they change their filter every 10–15 days. Keep an eye as the filter darkens and replace immediately.

THE WATER PROBLEM
+85% of American homes have hard water. But hardness varies dramatically — Portland sits at 10 PPM, Phoenix at 285 PPM, San Antonio at 357 PPM. If you moved cities, your water changed. Your hair and skin noticed even if you didn't.
Chlorine is added to every city's water supply to kill bacteria. That's good for drinking. But your skin isn't your stomach. Every unfiltered shower strips your skin's natural oil barrier — that "tight, dry" feeling after showering isn't clean. It's damage.
The white crusty buildup on your faucet? Those are calcium and magnesium deposits from your water. The same minerals are coating your scalp and hair every time you shower. Your shampoo applies on top of them — it can't reach your actual hair through the mineral layer.
One change fixes the source. Filter what your city doesn't, and your products, your skin, and your scalp can finally do what they're supposed to.

85% of homes across the world have hard water. It's loaded with chlorine, rust, and heavy metals that damage your skin and hair every time you shower.
Minerals crystallize on your scalp the same way they crust on your faucet — blocking follicles, trapping oil, causing itch and dandruff.
Heavy metals and mineral buildup suffocate follicles from the root — causing thinning, excessive shedding, and breakage.
Chlorine strips your skin's natural oil barrier every shower — leaving it dry, tight, irritated, and prone to breakouts.
The Theory Showerhead delivers a 200% pressure boost while meeting all US water flow regulations — including California's strict standards. Maximum performance, fully compliant.
Will this reduce my water pressure?
+No. The Theory Showerhead actually increases pressure by up to 200%. The micro-nozzle design compresses water flow — you get stronger pressure AND filtration at the same time. Most customers say it's the best pressure they've ever had.
How often do I need to replace the filter?
+Every 10–15 days on average, depending on your city's water quality. You'll know it's time when the filter starts to darken. When you pull it out and see what it caught, you'll understand why replacing it matters.
Does it actually remove chlorine, or is that just marketing?
+The activated carbon filter removes up to 99% of free chlorine. Most customers notice the difference immediately — the harsh chemical smell is gone from the first shower, skin feels less tight, and hair rinses cleaner. The results speak for themselves.
I've tried filtered showerheads before and they didn't work. Why is this different?
+Most cheap filters use a single layer of basic media that clogs in weeks. The Theory Showerhead uses a multi-stage system — activated carbon for chlorine, PP cotton for sediment and rust, mineral stones for rebalancing. Each layer handles a different contaminant. That's why it works where single-stage filters fail.
Is this safe for sensitive skin / eczema / psoriasis?
+Filtered water removes the chlorine and heavy metals that trigger flare-ups in the first place. Thousands of people with eczema and psoriasis report significant improvement after switching to filtered showerheads — many within the first week. We don't claim to cure any condition, but removing the irritant that aggravates it makes a real difference.
Can I take it with me if I move?
+Yes. It unscrews in 30 seconds, same as it went on. No permanent changes to your plumbing, no damage, nothing for your landlord to complain about. Take it to your next apartment, next city, next country — it fits any standard shower pipe worldwide.
Does this showerhead fit any shower?
+Yes! Our shower heads are designed with a universal G1/2" thread to fit any standard shower hose in the US, UK, and EU.
Can I adjust the pressure of the showerhead?
+Absolutely! Just adjust the pressure with our easy-to-use on/off switch located directly on the handle.
