RCSF-7 Shower Filter Cartridges (2-PACK), 20,000 Gallon Capacity
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.

Our advanced ThermalGuard™ catalytic carbon has been specially formulated to work well over a wide variety of temperature ranges, including hot water. Unlike competitive brand filters that still use KDF media, advanced Thermalguard™ delivers great performance while keeping the cost of replacement cartridges very economical. In fact, a single WaterChef shower filter cartridge is often less than half the price of the nearest leading competitive brand!
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.

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 – TRUST is what independently validated NSF/ANSI testing and certification 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...
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!
WHAT A DIFFERENCE!
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.
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!
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.
GET ONE TODAY!
Words can not describe how much I love my shower wand with filter! Best showers I’ve ever had, no kidding!
VERY HAPPY!
I am very happy with my water filter. I have great tasting water now. Three people in my apartment complex each bought the system and are extremely happy with it.
FIVE STARS.
I give this product and the company FIVE STARS. I wish every organization did business with was as helpful and friendly to deal with.
