Santé™ Ultimate Dual KDF Shower Filter With Handheld Shower Wand for City Water
The #1 Shower Filter On The Market - Packed With More Premium Filtration Media Than Any Other Shower Filter. More media means more protection.
Transform your shower into a wellness experience. The Santé™ Ultimate Dual KDF Shower Filter combines cutting-edge redox technology with premium-grade media to protect your body from over 600+ harmful contaminants lurking in city water. With up to 30 ounces of KDF-55, KDF-85, SIR-900, and Centaur Catalytic Carbon—far more than standard filters—it powerfully reduces chlorine, chloramine, PFAS, fluoride, heavy metals, VOCs, and more by up to 99.9%.
While other filters compromise with just a few ounces of carbon, the Ultimate Dual uses dual turbo action to maximize contact time without sacrificing water pressure. That means stronger protection and cleaner water, every shower.

What's Inside the Ultimate Dual
Four specialized filtration media work together to target a broader range of shower-water concerns.
KDF 55
Chlorine + Heavy Metals
Reduces chlorine, lead, mercury, nickel, and other heavy metals through a copper-zinc redox reaction. Also naturally bacteriostatic, helping inhibit the growth of bacteria, algae, and fungi inside the filter.
KDF 85
Chloramines + Iron + Manganese
Targets iron, manganese, and hydrogen sulfide(“rotten egg” odor) with high-efficiency redox filtration. Helps protect skin and hair from metal buildup and improves overall water clarity.
SIR 900
Fluoride + Arsenic
Specialized ion-exchange media designed to significantly reduce arsenic III & V, fluoride, and other trace contaminants. Provides an added layer of advanced protection not found in standard shower filters.
Catalytic Carbon
Chloramines + VOCs + PFAS
A highly reactive form of carbon that removes chlorine, chloramine, PFAS, VOCs, pesticides, and chemical impurities more effectively than standard carbon. Polishes water for cleaner smell and improved shower comfort.

Is Your Shower Secretly Sabotaging Your Skin?
Chlorine, heavy metals, and hard-water don’t just feel harsh – they’re culprits behind eczema, dryness, and sensitive skin.
-
Contaminated Water Weakens Your Skin’s Defenses
Studies show exposure to chlorine, heavy metals, and other water irritants can increase inflammation, redness, and flare-ups by as much as 87%.
-
Eczema Isn’t Just Genetic - It’s Environmental
A global review of 385,000 people found that those in hard-water regions had a 28% higher risk of eczema and chronic dryness.
-
Hot Showers = Chlorine Soak
In just 10 minutes under a hot shower, your body absorbs more chlorine through your skin and lungs than from drinking 8 full glasses of tap water.

Frequently Asked Questions
What is the difference between the City Water and Well Water versions?
The City Water version is designed for municipal water and targets chlorine, chloramines, fluoride, disinfection byproducts, heavy metals, VOCs, and other common city water contaminants. It uses a blend of KDF-55, KDF-85, SIR-900, and catalytic carbon.
The Well Water version is designed for homes on private well water or homes with existing whole house treatment. It uses KDF-55 to help reduce chlorine, heavy metals, scale, and other common well water concerns.
How do I know which configuration I need?
Customers using municipally treated water should generally select the City configuration. Customers using private well water should select the Well configuration. Because water quality varies by location, testing your water is the best way to identify your specific filtration needs.
What contaminants does the Ultimate Dual reduce?
The system is designed to reduce a broad range of contaminants commonly found in shower water, including chlorine, chloramine, heavy metals, iron, manganese, hydrogen sulfide, fluoride, arsenic, VOCs, and disinfection byproducts. Actual reduction may vary depending on water chemistry, temperature, flow rate, and contaminant concentration.
Does the Ultimate Dual reduce chlorine and chloramines?
Yes. The Ultimate Dual City Water version is designed to reduce both chlorine and chloramines. The City Water blend includes KDF-85 and catalytic carbon, which are especially important for chloramine reduction.
Does it reduce fluoride?
Yes, the Ultimate Dual City Water version includes SIR-900 filtration media, which is used for fluoride reduction (up to 90%).
Will it reduce water pressure?
The Ultimate Dual is designed to maintain strong shower pressure when installed correctly. A noticeable pressure reduction may indicate restricted flow, improper installation, clogged media, or that the cartridges are due for replacement.
How long do the cartridges last?
Under typical conditions, the cartridges last approximately 9–12 months. Lifespan may be shorter in homes with high contaminant levels, sediment, iron, or heavy shower usage.
Why is one cartridge heavier than the other?
This difference is intentional. The heavier cartridge contains dense, coarse-grain KDF 55, while the lighter cartridge contains finer-grain KDF 85 blended with SIR-900 and catalytic carbon.
Because these filtration media have different compositions, grain sizes, and densities, the cartridges are not designed to weigh the same. Each cartridge serves a different filtration purpose, allowing the Ultimate Dual to provide broader contaminant reduction.
Can I use it with hot water?
Yes. The system is designed for normal shower temperatures. For best media performance and longevity, we recommend keeping the water temperature at or below 140°F.
Will it soften my water?
The Ultimate Dual is not a traditional water softener and does not remove hardness minerals in the same way as an ion-exchange softening system. However, the filtration media may help reduce scale formation and improve how the water feels.
Install
Will it fit my shower?
The Ultimate Dual is designed for standard U.S. 1/2" shower connections. Certain specialty, rainfall, recessed, or proprietary showerhead designs may require an adapter or alternative installation method.
Can I install it myself?
Yes. The system is designed for straightforward installation and typically does not require a plumber. Installation difficulty may vary with nonstandard shower configurations.
Why is my filter leaking after installation?
Leaks are most often caused by missing or incorrectly positioned washers, insufficient plumber’s tape, loose connections, or overtightening. Follow the included installation instructions carefully and contact us if assistance is needed.
How much plumber’s tape should I use?
Wrap plumber’s tape clockwise around the shower-arm threads two to three times before attaching the system.
Do I need to flush the cartridges before use?
After installation, run the shower for one to two minutes to flush out any loose media fines that may be present from shipping.
To be honest I was somewhat skeptical before trying this shower filter. Its design seemed cumbersome and high maintenance. Very happy I was wrong. This filter has been nothing short of a wonderful experience to shower with. The quality of the water it outputs is ultra clean and is easily the best shower filter I've used living in New York City. Trust me I have over the years probably tried eight other brands and the Santé Ultimate Dual sits clearly at the top and is worth every penny! It's actually modestly priced considering how powerful it is. I look forward to recommending this product to all my friends and family.
The water filter works fine. I can feel the difference between the filtered water vs non filtered water. The shower head doesn't seat properly inside it's holder. The shower head continues to pop out of it when the hose is touched.
Hi Wilkerson, thank you so much for your review! We’re happy to hear the filter is working well and that you can feel a difference in the water.
We’re sorry the handheld wand isn’t sitting securely in the holder. It looks like the hose connections are reversed. The end currently attached to the handheld wand should connect to the mounting bracket instead. Once the hose is flipped around, the wand should sit securely in the holder.
Please reach out if you need any help!
I've been using these filters for a couple of years and they work great. The shower water used to smell like chlorine,but with these the smell is gone.
I have been using Shower Filter✨’s for over 25 years and this is by far the very best Shower Filter✨ I have ever had!✨ I can feel a big, positive powerful difference in my hair, skin, and the way I feel.❤️ I highly recommend it right away and you will be so grateful and thankful.💞 Thank you Sante. ❤️ Love & Light!💖
I love my shower filter so much. I can genuinely feel a big difference in my hair and skin since using it, and it’s such a relief to be showering without harsh chemicals. This has been a game changer for me, and I highly recommend it!
10/10!
I have been quite satisfied with my shower filter, it has helped with my allergies extensively. I have reordered the refills and I ordered a new one for our rental unit.
Please that they sent a reminder for new filter replacement great help
If you have well water you absolutely need this. I have blond hair. Before I got this filter my hair kept turning orange. Not pretty.
There is a clear noticeable difference in the water quality and I love it! Especially in Chicago, the water is pretty high in chlorine. And I'm noticing significant less irritation on my skin because of it. Thank you!
Nice clean water from the filter assembly. Perfect for removing impurities in city municipality water, especially the Chloramine disinfectant.
Seems effective! Easy installation.
What a wonderful gift! After living in Tucson for over 50 years with increasingly "hard" groundwater-sourced city water, and now in the process of a demanding detoxing protocol, I am able to enjoy a shower and wash my hair without concern for burning my eyes! I am so appreciative! And for you excellent service and helpfulness as a small company - thank you!
Was not happy with my wife for ordering
I installed this filter a couple of years ago because from my extensive research, it's the best on the market. I live in a desert city where nuclear testing was done in the 50's-60's. My tap water has insane levels of arsenic, heavy metals, halides; all kinds of nasty stuff. I can absolutely feel a difference in my skin, hair, and overall health. I'm a customer for life. It's totally worth it.
We moved to the country and this has been a game changer for our well water. It has reduced the sulfur smell tremendously!
great product. hope to be a customer for life.
This works surprisingly well. My face and skin have cleared up dramatically since we started using this filter on our shower. I would highly recommend to anyone with a well who is considering a filter.
Perfect
Love my filters !!
I love my shower head
Got one for my Son as well !!
It has taken all the chlorine and other harsh chemicals out of my water. Now my skin does not get easily irritated or red or get that kind of prickly feel from things!. It seems my cologne and fabric softener sheets doesn't irritate my skin like it used to since I have been using your shower filter. Thanks!
Game changer. Live in LA with really bad water, chloromine and heavy metals. Got fed up with my hair color getting brassy and discolored. This dual filter has helped immensely. My hair stylist is amazed! Great product and great service!
Very easy to change and install. Came In a timely matter
Happy they came out with a refill set. Easy to install.
The cartridges were easy to install and now I have great water in my shower again.
