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. Scott, WaterChef Customer
WaterChef® Premium Under-Sink Water Filtration
Enjoy Premium Quality Water for a Fraction of the Cost.
Your Ultimate Drinking Water Solution!
Powerful Big Block™ Carbon Filtration – 1,000 GALLONS per Cartridge!
Combining the power of solid carbon block filtration with a unique, proprietary blend of additional filter medias, WaterChef’s exclusive Big Block™ Filtration technology maximizes contaminant reduction and delivers up to 1,000 GALLONS (3,785 L) of freshly filtered water with a single cartridge!
This unique formula provides unsurpassed contaminant reduction for a broad range of common tap water contaminants including: Lead, Chlorine, Chloramine, Cysts (including Giardia and Cryptosporidium), Chlorine By-Products (such as Trihalomethanes), Synthetic Contaminants (such as Pesticides and Herbicides), Industrial Contaminants (such as Volatile Organic Compounds (VOCs)) and Petroleum Contaminants (such as Benzene and MTBE), while allowing 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 filtration technologies such as Reverse Osmosis and Distillation).

Greater Savings and Convenience. Less Waste.
Stop being nickel and dimed to death by small, costly and less effective filter replacement cartridges. With a WaterChef filtration system, 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 cartridge replacement per year! (Compare that to pitcher filters, faucet filters and refrigerator filters that are so small that they can require as many as 25 replacements per year!) And, fewer cartridges to change means less waste for the environment too!
Intelligent Monitor™ – No More Cartridge Replacement Guesswork!
Intelligent Monitoring takes the guesswork out of cartridge replacement. Unlike other systems with simple timer-based monitors, WaterChef's Intelligent Monitor measures actual usage, so you will never discard a cartridge prematurely or continue using one that has exceeded its rated capacity!
For added convenience, the Intelligent Monitor's LED indicators are built right into the system's premium designer faucet –
GREEN: normal system operation
YELLOW: under 10% of capacity remains (time to order a replacement cartridge)
RED: capacity has been reached (replace cartridge to insure peak performance)
Includes Premium Grade Designer Faucet with Built-in LED Indicators
WaterChef’s Designer Series Faucet is a premium grade, single-temperature faucet that features solid forged brass construction (NSF Standard 61 compliant), a ceramic disc valve for reliability, a spout with aerator tip for a steady stream and the convenience of LED indicators (for the Intelligent Monitor) built right into the faucet base ring.
This faucet compliments today’s high-end kitchens with its versatile design and choice of four premium finishes. Choose from polished chrome, polished brass, brushed nickel and oil-rubbed bronze finishes.
Filter Your Sink AND Your Refrigerator with a Refrigerator Kit (optional)
Say goodbye to the inconvenience and expense of the frequent cartridge replacements required by small (and less effective) refrigerator filters. By adding an optional Refrigerator Kit (sold separately) to your U9000 Under-Sink Filtration System, you can easily supply premium filtered water to both your sink and your refrigerator with a single filter cartridge for up to one year!
Tested & Certified by NSF® International for Performance You Can Trust

WaterChef® Premium Under-Sink Water Filtration
Frequently Asked Questions
Q: How often do the filter cartridges in the WaterChef U9000 System need to be changed?
A: 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 and the convenience of 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.
Q: How will I know when it is time to replace my filter cartridge?
A: 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 obtain a new filter cartridge.
Q: Why do the filter cartridges need to be changed?
A: 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.
Q: Why is independent certification of water filtration products important?
A: Simply put, having a trusted, independent “third party” organization like NSF International, WQA, or UL evaluate a water filtration product against an official standard or protocol that has been developed by industry experts, public health officials, and users and consumer representatives, gives you the best means for making a sound and informed choice about the claims of the product. Some water filtration manufacturers have nicely outfitted laboratories with talented scientists to develop great products, but you would have to know them very well and how they stand by their core values to trust whether the performance claims they make for their products are true or misleading. Having a trusted organization “validate” their claims will give you the peace of mind you are looking for when it comes to selecting a system for you and your family.
Q: Does this system remove beneficial minerals from the water?
A: No. Beneficial minerals such as calcium and magnesium pass freely through the system, resulting in water that is both great tasting and naturally balanced.
Q: Does this system reduce Total Dissolved Solids (TDS) from the water?
A: No. 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 designed to reduce unwanted contaminants, while leaving the beneficial minerals in.
Q: Does this system reduce sulfur odor (rotten egg smell) in my water?
A: Yes. WaterChef drinking water systems have been independently tested and certified by NSF for the reduction of odor, including the rotten egg smell that is often associated with sulfur.
Q: Does this system remove fluoride from the water?
A: 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 either NSF® or the Water Quality Association (WQA) 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.
Q: Can the water from the WaterChef U9000 System be dispensed from my refrigerator?
A: Yes. By adding the optional Refrigeration Kit (which includes tubing and fittings), a single U9000 System can be used to dispense filter water from both your faucet and your refrigerator, eliminating the added hassle and expense of replacing refrigerator filters.
Q: Can the WaterChef U9000 System be used with an instant hot water appliance for "hot" filtered water?
A: Yes, under certain conditions. When the U9000 System is used in conjunction with an instant hot water appliance, a dual temperature (vented) faucet is required. A single temperature faucet (included with the U9000 System) is only intended for use with cold (ambient) water supplies. If you are interested in using this system with an instant hot water appliance, please call Customer Care at 1-800-879-8909 for additional information.
Q: Can this system be used to filter well water?
A: 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.

I replaced a Aquasana under sink system with the WaterChef, and never looked back. I now change my filter every 8-10 months vs. every 3 months. My water tastes great and is crystal clear. I think this is the best under sink system available.
Love our WaterChef U9000 under the sink filter
Posted by David Straub on 1st Sep 2018
We have had our WaterChef U9000 for more than a year now. When I installed it, I was very impressed with the quality of the product. The faucet material has a high end finish that matched perfectly with our other kitchen sink fixtures. The water that comes from this filter tastes great. The L.E.D. indicators on the facet base are an excellent feature that allows us to know when it is time to replace the filter cartridge. This is an outstanding product.
Wonderful undersink filter
Posted by June on 21st May 2018
I am using the same filter now for two years, as it is just the two of us. Having the filter under the sink is so nice. We don't have to change the filters on the faucet anymore. And I am sure it is a savings too. Learning that the filter will take care of lead is very good because you never know whats in the pipe system, etc.
Can't get it to stop leaking!
Posted by Michael Lynch on 5th Mar 2018
I purchased the U9000 about a year ago. The housing was defective and had to be replaced. When it came time to replace the filter, I followed the instructions implicitely but the unit started leaking water. My contractor spent several hours trying to fix it but the leaking continued from the tubes and the seal. It is completely unusable.
We are very sorry to hear this, Michael. Your U9000 System includes a LIFETIME Limited Warranty. Please contact our Customer Care team at 1-800-879-8909 at your earliest convenience so we can assist you.
Great Company, Great Product
Posted by Lowell Tanzer on 16th Jan 2018
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.
WaterChef is customer service focused. We use their Auto-Ship option, which allows flexibility in changing delivery dates, which has worked well for us.
We very highly recommend both the Company and the product.
Product and Service the Absolute Best
Posted by Les on 12th Jan 2018
My U9000 had a sensor lights that did not flash as water ran. WaterChef sent me a complete sensor kit which arrived within a few days. This is the trim ring, sensor, battery, and under counter nut and spacer. The replacement took me minutes and everything worked perfectly.
The customer service at WaterChef was courteous, fast, and on point. Their filter is simply top notch too.
I would recommend them to everyone.
Instructions and lighting aren’t complete
Posted by David Middleton on 11th Dec 2017
We’ve had our U9000 for one year. First of all, our light signals on the faucet to alert when it’s time to change don’t work. Disappointed for $300+.
Secondly, the instruction sheets are poorly marked and cheaply graphed. They don’t integrate the changing of the print and on what side for sure is up. Again, you’d expect this out of a filter system that is $100 or less. If you haven’t bought yet, don’t spend the premium for an average at best product.
Thank you for your feedback, David. We are very sorry to hear of your experience. Your U9000 System includes a LIFETIME Limited Warranty. Please contact our Customer Care team at 1-800-879-8909 and we will be happy to assist you.
Great product and great customer service
Posted by Terri on 4th Nov 2017
I purchased the U9000 Premium Under-Sink water filtration system after extensive research. I couldn't be happier! The oil rubbed bronze faucet is beautiful! The system is awesome. Flow of water is great. I love the green, yellow and red lights to let you know when to change the filter. Water tastes great. Customer service is the best! All my questions via email were answered within the hour and customer service was above and beyond any company I have ever dealt with for anything. Very polite and accommodating!!
Waterchef a great company that stands behind their product.
Posted by Debbie on 1st Jun 2017
Had an issue with the under counter unit. Called the company the owner called me back. They were very nice fixed the problem. I'm very satisfied and ordered another unit from them. What a pleasure to deal with Waterchef.
Thank You for taking care of the problem.
After Four Years Our U9000 is Still Performing Like a Champ!
Posted by Gary Lynn on 10th Apr 2017
We absolutely love this water filter system! After four years of daily use, it still performs as well as the day we installed it. The filter cartridges work as promised and the water tastes great through the entire filter life (without filtering, our tap water tastes awful). Our system faucet finish still looks great and operates as if it were new (no reduced water flow). Great job, WaterChef!

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. Bridget C., WaterChef Customer
