OVERVIEW

WaterChef® – Premium Shower Filter Cartridges

EXPERIENCE THE DIFFERENCE AND MAKE EVERY DAY A SPA DAY

WaterChef® Shower Filter Replacement Cartridges (RCSF-7) utilize advanced ThermalGuard™ catalytic carbon technology to substantially reduce your exposure to chlorine, leaving your body’s natural oils and proteins intact. This results in immediate cosmetic benefits, including softer and more manageable hair, healthier and smoother skin, and reduced eye irritation. Additionally, you may notice that you use less soap and conditioner, and if you use hair color products, you may also experience longer-lasting color between treatments.

easy cartridge changes

WaterChef's advanced ThermalGuard™ catalytic carbon formula has been meticulously engineered to excel in reducing chlorine across a broad temperature range, including hot water. Unlike competing brands struggling to achieve a mere 50% chlorine reduction, WaterChef proudly holds NSF/ANSI certification from IAPMO R&T, attesting to its remarkable ability to eliminate 96.6% of chlorine for up to 10,000 gallons per filter cartridge!

Say goodbye to outdated KDF media used by rival shower systems. Our proprietary ThermalGuard™ carbon formula not only delivers superior performance but also keeps replacement costs remarkably low. In fact, a WaterChef RCSF-7 shower filter cartridge typically costs less than half of what competing brands charge. With a generous capacity of up to 10,000 gallons or 6 months, that translates to just two filter cartridges (or one 2-Pack) per year for most users. Immerse yourself in the pinnacle of shower filtration with WaterChef, where advanced technology meets affordability.

Sadly, the water filtration industry is riddled with manufacturers that make unvalidated and exaggerated performance claims. Rest assured knowing that WaterChef has invested in independent NSF/ANSI testing and certification by one of the industry's most trusted authorities, IAPMO R&T. IAPMO requires the strictest testing and compliance standards and is valued by consumers, manufacturers, retailers, and regulatory agencies across the globe.

IAPMO Platinum Seal

WaterChef Shower Filter Systems and Cartridges are independently tested and certified by IAPMO for NSF/ANSI Standard 177 for chlorine reduction. (NOTE: Standard 177 for chlorine reduction is the only NSF/ANSI Standard currently existing for shower filtration performance. Other brands' additional chemical reduction claims are not NSF/ANSI certified claims.)

Don’t be fooled by unvalidated performance claims – TRUST is what independent NSF/ANSI testing and certification by IAPMO is all about.

OUR CUSTOMERS SAY IT BEST

BEST BUY OF 2022
I'm obsessed! My hair was getting so dry, frizzy and damaged no matter how much money I spent on expensive hair products. I bought this water filter and it's softer than ever...
— Keri B., WaterChef SF-7C Customer
WONDERFUL SHOWER
Replace whatever you have with this! Wonderful shower head, great pressure, with good water flow settings. Blows the competition out of the water!
— Coleton A., WaterChef SF-7C Customer

Oh my god! What a difference in my water! I am so glad I found this! I will buy this product a millions times over again! If you are looking for a water filtration system for you home, WaterChef is the product you want. Great tasting water at its best!

GREAT UPGRADE
Replaced my Culligan 2 cartridge under counter filter with this. It’s going to be so much easier to replace the filter cartridge. Water flows out probably 30% faster and tastes great. Install was simple.
— David S., WaterChef U9000 Customer
REAL WATER!
I knew I had made the right decision to buy this product when I first took a drink of the filtered water. It didn't have a funny taste to it which was a problem with my previous system. I also loved the slim design of the casing. Thanks a heap!
— Charles C., WaterChef C7000 Customer
WHY DID WE WAIT SO LONG?
We are very happy with our new filter. Not sure why we waited this long to get one, installed very easy and the water is clean and smooth! Thank you.
— Joshua K., WaterChef U9000 Customer
