WaterChef® Premium Shower Filter Cartridges

Make Every Day a Spa Day!

Experience the Difference of a WaterChef® Shower!

Superior Chlorine Reduction - Feel the Difference Immediately!

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.

Premium Shower Filtration - Lower Cost!

WaterChef shower filters - quick and easy cartridge replacementsOur 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!

Tested & Certified by WQA - Trusted Filtration.

WQA Gold Seal

  1. Great Shower Experience!

    These shower filters are extremely easy to install and make a huge difference in the quality of my shower by removing the horrible chlorine smell. Helps keep my skin soft and the wand makes reaching around very convenient.

    Posted by Unknown on 21st Sep 2020

    I have been using these for about 4 years and I love auto-ship. When my cartridge shows up every 4 months, I replace it with little effort and my water starts to feel better again instantly. Great product and great customer service team when I need help adjusting my subscription.
