U9000 Premium Under-Sink Water Filtration System with Intelligent Monitor, 1,000 Gal.
WaterChef® U9000 Under-Sink Water Filtration System
ELEVATE YOUR DRINKING WATER WITH THE ULTIMATE UNDER-SINK SOLUTION
Combining the power of solid carbon block filtration with a unique blend of proprietary filter media, WaterChef’s exclusive Big Block™ filtration technology maximizes contaminant reduction. This innovative sink filter seamlessly delivers 1,000 gallons (3,785 L) or up to a full year of impeccably filtered drinking water from a single cartridge.
Big Block™ Technology provides superior contaminant reduction for a broad range of 78 common tap water contaminants, including:
- Lead
- Mercury
- Cysts (including Giardia and Cryptosporidium)
- Chlorine
- Chloramine
- Microplastics
- PFOA/PFOS
- Chlorine By-Products (includes Trihalomethanes)
- Synthetic Contaminants (includes Pesticides and Herbicides)
- Industrial Contaminants (includes Volatile Organic Compounds (VOCs))
- NSF/ANSI Standard 401 Emerging Contaminants (includes Pharmaceuticals and Detergents)
- Petroleum Contaminants (includes Benzene and MTBE)
Furthermore, our unique formulation allows beneficial essential minerals (such as Calcium, Magnesium, and Potassium) to remain in your drinking water. This ensures great-tasting water that is cleaner, healthier, AND naturally balanced (without the de-mineralization and 'flat' taste associated with other water filtration methods like Reverse Osmosis and Distillation).
The U9000 also tackles sulfur odors in drinking water and is suitable for filtering municipally treated water supplies and well water from most disinfected wells. (For well users, we recommend water testing before purchasing any home water filter treatment system. This will ensure that you choose the best filter system for your specific needs.)

Stop being nickel and dimed by small, costly, and less effective water filter replacement cartridges. With a WaterChef U9000 Under-Sink Water Filtration System, you'll experience the luxury of better-tasting, premium-quality water at a fraction of the cost. Simply turn on your tap and enjoy a continuous flow of fresh, filtered water on demand.
Enjoy the added convenience of an impressive 1,000 GALLON rated capacity, equivalent to over 7,500 plastic water bottles. For most families, this translates to just one cartridge replacement per year! (Contrast that with the frequent replacements required for the tiny cartridges found in pitcher and faucet filters, which not only remove less but demand up to 25 replacements annually.)
Beyond cost savings, fewer water filter cartridges mean less waste. When it's time for a new filter, effortlessly order online at waterchef.com or simplify your life with an Auto-Ship subscription to receive your cartridges automatically when needed.

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.
WaterChef’s Designer Series Faucet is a premium-grade, single-temperature faucet meticulously crafted with solid forged brass construction, meeting NSF/ANSI/CAN 61 compliance standards. Reliability is assured through a ceramic disc valve, while a dedicated aerator tip ensures a consistent and smooth 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. And because the filter system is discreetly positioned under the sink, you reclaim valuable counter and refrigerator space, eliminating the need for bulky pitcher filters.
Designed to complement today's high-end kitchens, this faucet is available in four beautiful finishes: chrome, brushed nickel, polished brass, or oil-rubbed bronze.
PRO TIP: An existing spray attachment or soap dispenser may be removed as an alternative to drilling an additional sink hole to install the dedicated system faucet.
Bid farewell to the inconvenience and cost of frequent refrigerator filter replacements. Incorporate an optional Refrigerator Kit (sold separately) into your under-counter filter installation. Once installed, you can effortlessly supply premium-quality water to both your sink and your refrigerator from your U9000 System.

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!
