WaterChef® U9000 Under-Sink Water Filter System
YOUR ULTIMATE UNDER SINK WATER FILTRATION SOLUTION
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. This effective sink filter delivers 1,000 gallons (3,785 L) or up to one year of freshly filtered drinking water from a single cartridge.
The unique formulation provides superior contaminant reduction for a broad range of 75 common tap water contaminants, including:
- Lead
- Mercury
- Cysts (including Giardia and Cryptosporidium)
- Chlorine
- Chloramine
- Chlorine By-Products (includes Trihalomethanes)
- Synthetic Contaminants (includes Pesticides and Herbicides)
- Industrial Contaminants (includes Volatile Organic Compounds (VOCs))
- Emerging Contaminants (includes Pharmaceuticals and Detergents)
- Petroleum Contaminants (includes Benzene and MTBE)
Additionally, this media formulation allows beneficial minerals (such as Calcium, Magnesium and Potassium) to remain in the water. This results in great-tasting water that is cleaner, healthier, AND naturally balanced (without the de-mineralization and "flat" taste associated with other filtration methods such as Reverse Osmosis and Distillation).
It also reduces sulfur odors in water and can be used to filter municipally treated water supplies and well water from most disinfected wells. (If you are on a well, it is advisable to have your water tested before purchasing any home water treatment system. This will ensure that you chose the best filter system for your specific needs.)

Stop being nickel and dimed to death by small, costly, and less effective replacement cartridges. With a WaterChef U9000 Under-Sink Water Filtration System, you get better-tasting, premium quality water at a fraction of the cost. Simply turn on your tap and enjoy a stream of fresh, filtered water on demand.
You’ll also enjoy the convenience of a huge 1,000 GALLON rated capacity. (That’s over 7,500 plastic water bottles!) For most families, that means just one cartridge replacement per year! (Compare that to the tiny cartridges in pitcher and faucet filters. They remove less and require up to 25 replacements per year.)
And, fewer filter cartridges means less waste too. When you do need a new filter, you can easily order them online at waterchef.com or add an easy-to-manage Auto-Ship subscription to receive your cartridges automatically when you need them.
Intelligent Monitoring takes the guesswork out of cartridge replacement. Unlike other water filters for sinks with simple timer-based monitors, WaterChef's Intelligent Monitor measures your actual usage, so you'll never discard a cartridge prematurely or continue using one that has exceeded its rated capacity again. For added convenience, LED indicators are built right into the system's premium grade designer faucet.
WaterChef’s Designer Series Faucet is a premium grade, single-temperature faucet with solid forged brass construction (NSF/ANSI/CAN 61 compliant). It also features a ceramic disc valve for reliability and an aerator tip for a steady stream. For added convenience, the Inelligent Monitor™ LED indicators are built right into the faucet base. And because the system is located discreetly under the sink, you won't take up space on your counter or in your refrigerator with pitcher filters.
This faucet complements today’s high-end kitchens with its clean, modern design and choice of four beautiful finishes. Choose from chrome, brushed nickel, polished brass, or oil-rubbed bronze.
INSTALLATION 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.
Say goodbye to the hassle and expense of frequent refrigerator filter replacements. Simply add an optional Refrigerator Kit (sold separately) to your under counter filter installation. Once installed, you'll be supplying premium quality water to both your sink and your refrigerator from a single U9000 System.
Sadly, the water filtration industry is riddled with manufacturers and sellers who make unvalidated and exaggerated performance claims. You can rest assured knowing that WaterChef has invested in independent NSF/ANSI testing and certification by one of the industry's most trusted authorities, the Water Quality Association (WQA). WQA requires the strictest of testing and compliance standards. They are valued worldwide by consumers, manufacturers, retailers, and regulatory agencies. Trust is what independent NSF/ANSI Certification is all about.

Based on WQA testing data with typical water contitions. Actual performance may vary.
I give this product and the company FIVE STARS. I wish every organization I did business with was as helpful and friendly to deal with...When you look at other products on the market, many of them require frequent cartridge replacement which is great for those manufacturers, but not so convenient or cost effective for the consumer.
The unit itself is very well made and the faucet looks so nice on the sink. We started using this product the night we got it and the water is so pure and clean coming out which makes the taste of the water amazing. I would absolutely recommend this product to anyone.
We've used many different water filtration systems over the years, but the U9000 has been the overwhelmingly best performer. We've been using it now for over 3 years and couldn't be more pleased. Water tastes great and the ease of changing filters each year is a non-event. Thankfully. We very highly recommend both the Company and the product.
We love our new Under the Counter WaterChef! Looks great, takes small space underneath, will be easy to replace the filter, looks amazing and I don’t need to worry about when to replace filter because of the indicator light! Love It! I would definitely recommend and buy one again.

FAQS
Have an Additional Question? Just Ask Us. 
WaterChef filtration products are all about performance, style and value! Not only do you get a system that looks great and performs to your expectations, but one that is also designed to provide up to 1,000 gallons with a single filter cartridge! That means an average family of four can enjoy freshly filtered water for just pennies a day with the convenience of just one cartridge replacement per year – great for your wallet and your busy schedule! Of course, if you have more thirsty people in your family, or just simply enjoy a lot of water, you can replace the filter more often.
The U9000 System has an electronic Intelligent Monitor that tracks how much water has gone through the filter, so it will let you know when to change it. And, it will also give you a warning before the cartridge is completely used up so you will have time to order a new replacement filter cartridge.
WaterChef filter systems have been certified to reduce the contaminants claimed on the performance data sheet. Every filter has a limited amount of capacity for the contaminants it captures. Even though water is still flowing through it and may still taste fresh, there comes a point when it is no longer providing the performance it had when new. Therefore, it is important to change the filter on time to get the best performance from it. There is nothing wrong with changing it ahead of time if you notice a return of off taste or odor similar to the tap water. A sudden or temporary change may be normal with seasonal factors or activities of the municipal water provider.
In an industry riddled with unvalidated and misleading performance claims, having a trusted, independent “third party” organization like WQA, NSF and IAPMO evaluate a water filtration system against an "official" standard or protocol that has been developed by industry experts, public health officials and consumer representatives, gives you the ability to make a sound and informed choice about the performance claims of the system.
Some water filter manufacturers base their performance claims on internal test results from their own laboratories, but you would have to know them very well to trust whether the performance claims they make for their products are true or misleading. Having a trusted testing organization “validate” performance claims gives you the peace of mind you are looking for when it comes to selecting the right system for you and your family.
NO. Beneficial minerals (such as calcium and magnesium) pass freely through the system. This provides you with filtered water that is both great tasting and naturally balanced.
NO. TDS is a poor measure of water quality. TDS in drinking water is usually attributed to the amount of calcium, potassium, and magnesium that is present in your water supply. These are beneficial minerals that are known to support good health. WaterChef systems have been specifically designed to reduce a broad range of unwanted contaminants while leaving these beneficial minerals in.
YES. All WaterChef drinking water filter systems have been independently tested and certified by WQA for the reduction of odor, including the rotten egg smell that is often associated with sulfur.
NO. While it does have a limited ability to reduce fluoride, it is very dependent upon the pH of the water. If you've had your water tested and find that fluoride is a major concern for you, we recommend finding a reputable manufacturer for either a reverse osmosis or distillation system. Be sure that the system has been independently tested and certified by WQA (the Water Quality Association), NSF or IAPMO for fluoride reduction. If you have questions or would like assistance, please call WaterChef Customer Care at 1-800-879-8909. One of our support specialists can help you find a reputable manufacturer that fits your specific needs.
YES. While this system has been specifically designed to reduce contaminants that are most commonly found in municipally treated water supplies, it also has the ability to work well on most disinfected wells.
Prior to making the decision to purchase any home water treatment system, it is advisable to have your well water tested first. Once you have your test report, call WaterChef Customer Care at 1-800-879-8909 and request to have one of our water quality specialists review the specific substances and contaminants shown on your report. This will help us to determine whether this system is the right solution for you.
