OVERVIEW

WaterChef® Premium Under-Sink Filter Cartridges

ENJOY SUPERIOR PERFORMANCE AND A 1,000 GALLON RATED CAPACITY!

Combining the power of solid carbon block filtration with a unique, proprietary blend of additional filter media, WaterChef’s innovative Big Block™ Filtration technology maximizes contaminant reduction and delivers up to 1,000 GALLONS (3,785 L) of freshly filtered water with a single filter cartridge!

This unique formula provides unsurpassed contaminant reduction for a broad range of common tap water contaminants including:

  • Lead
  • Mercury
  • Microplastics
  • Cysts (including Giardia and Cryptosporidium)
  • Chlorine
  • Chloramine
  • Microplastics
  • PFOA/PFOS
  • Chlorine By-Products (such as Trihalomethanes)
  • Synthetic Contaminants (such as Pesticides and Herbicides)
  • Industrial Contaminants (such as Volatile Organic Compounds (VOCs))
  • NSF/ANSI Standard 401 Emerging Contaminants (such as Pharmaceuticals and Detergents)
  • Petroleum Contaminants (such as Benzene and MTBE)

Additionally, the UR90's unique media formulation allows beneficial minerals (such as Calcium, Magnesium, and Potassium) to remain in the water. The result is great-tasting water that is cleaner, healthier, and naturally balanced (without the de-mineralization and “flat” taste associated with other water filtration technologies like reverse osmosis and distillation).

easy filter changes

With WaterChef you’ll enjoy premium quality water at a fraction of the cost! You’ll also enjoy the convenience of a 1,000 GALLON rated cartridge capacity (That’s over 7,500 plastic water bottles!).

For most households, that translates into just ONE filter cartridge replacement per YEAR! (Compare that to the cartridges for pitcher filters, faucet filters and refrigerator filters that are so tiny that they can require as many as 25 replacements per year!) Plus, fewer cartridges to change means less waste too!

IAPMO Platinum Seal Sadly, the water filtration industry is riddled with manufacturers and sellers who 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 Research and Testing.

Requiring the strictest of testing and compliance standards, the IAPMO Platinum Seal is awarded to only the most reliable and trusted producers of quality water treatment systems. IAPMO is valued by consumers, manufacturers, retailers, and regulatory agencies across the globe. Trust is what independent NSF/ANSI 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...
— 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!

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
