WaterChef® U9000 Under-Sink Water Filtration System
ELEVATE YOUR DRINKING WATER WITH THE ULTIMATE UNDER-SINK SOLUTION
Experience the ultimate in water filtration with WaterChef’s Big Block™ Technology, an innovative solution that combines the power of solid carbon block filtration with a unique blend of proprietary filter media. Engineered for maximum contaminant reduction, this advanced sink filter technology delivers up to 1,000 gallons (3,785 liters) of impeccably filtered water from a single cartridge—equivalent to an entire year of fresh, clean drinking water for most households.
The U9000 System is NSF/ANSI Certified for Superior Reduction of 78 Common Tap Water Contaminants, Including:
- Heavy Metals: Lead, Mercury
- Pathogens: Cysts (including Giardia and Cryptosporidium)
- Disinfectants: Chlorine, Chloramine
- PFAS "Forever Chemicals": PFOA, PFOS
- Microplastics
- Chlorine By-Products (includes Trihalomethanes)
- Synthetic Contaminants (includes Pesticides and Herbicides)
- Industrial Contaminants (includes Volatile Organic Compounds (VOCs))
- Petroleum-Based Contaminants (includes Benzene and MTBE)
- Emerging Contaminants: Pharmaceuticals, Detergents (NSF/ANSI Standard 401)
The U9000 not only filters municipally treated water but also reduces sulfur odors in well water from most disinfected sources. (For well users, we recommend water testing to ensure the system meets your specific needs.)

Unlike other filtration methods like reverse osmosis or distillation, Big Block™ Technology preserves beneficial essential minerals such as Calcium, Magnesium, and Potassium in your water. This ensures a naturally balanced, refreshing taste without the de-mineralization and "flat" flavor associated with over-processed water.
Stop overpaying for small, less effective water filter cartridges that require constant replacements. With the WaterChef U9000 Under-Sink Water Filtration System, you'll enjoy the luxury of great-tasting, premium-quality water at a fraction of the cost—all directly from your tap.
Featuring an impressive 1,000-gallon capacity, the U9000 is designed to handle the needs of most households with ease, delivering the equivalent of over 7,500 plastic water bottles—all with just one cartridge replacement per year! (Compare that to traditional pitcher and faucet filters that not only remove fewer impurities but require up to 25 costly replacements annually.)
Not only will you save money, but you’ll also reduce waste. Fewer cartridge replacements mean less environmental impact, making the U9000 a smart, eco-friendly choice for your home.
When it’s time for a new filter, ordering is simple. Visit waterchef.com to purchase your replacement or opt for an Auto-Ship subscription to have cartridges delivered automatically—hassle-free, right when you need them.
Intelligent Monitoring takes the guesswork out of cartridge replacement. Unlike conventional water filters for sinks with simple timer-based monitors, our Intelligent Monitor goes beyond by measuring your actual usage. You'll never discard a cartridge prematurely or continue using one that has exceeded its rated capacity again.
Upgrade your kitchen with WaterChef’s Designer Series Faucet. Expertly crafted from solid forged brass and built to meet NSF/ANSI/CAN 61 standards, this premium single-temperature faucet combines durability with style. A ceramic disc valve ensures long-lasting reliability, while a precision-engineered aerator delivers a smooth, steady water stream.
For added convenience, the Intelligent Monitor™ LED indicators are seamlessly integrated into the faucet base, providing real-time feedback for easy filter changes. Plus, with the system’s under-sink design, you’ll free up precious counter and refrigerator space, eliminating the clutter of bulky pitcher filters.
Available in four stunning finishes—chrome, brushed nickel, oil-rubbed bronze, or polished brass—this faucet is designed to complement today's luxury kitchens.
PRO TIP: Replace an existing spray attachment or soap dispenser to install the system faucet without adding a new sink hole.
Bid farewell to the hassle and expense of frequent refrigerator filter replacements. With the optional Refrigerator Kit (sold separately) the U9000 seamlessly delivers premium-quality water to both your sink and refrigerator. Enjoy the convenience of filtered water and ice, all powered by one efficient filtration system.

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!

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.
