From their humble beginnings 30 years ago with an idea and a friend’s garage, to their current state-of-the-art manufacturing plant in the Sierra Nevada Mountains, the WaterChef Premium Water Filtration is an exclusive online retail brand of Water Safety Corporation. For 30 years, WaterChef has been creating, manufacturing, and shipping top-notch water filtration systems to customers, distributors, and dealers worldwide.

When shopping for an under sink water filter system, the most crucial factor to take into account is the product’s contaminant reduction technology. If you find a filter that has been tested and proven to remove all harmful contaminants, then the other features are icing on the cake. The WaterChef U9000 is a filter that protects against 75 harmful pollutants and also comes with a myriad of “icing on the cake” features.

Key Features of the WaterChef U9000 Filtration System

WaterChef U9000 is WQA Gold Seal Certified for 75 contaminants as well as tested and certified by NSF International NSF/ANSI Standards 42, 53, and 401. The powerful Big Block Technology combines a solid carbon block filtration with a proprietary blend of additional filter media in order to effectively remove harmful substances from either your city or well water while allowing beneficial minerals such as calcium, magnesium, and potassium, to remain.

The Proprietary 3-Ply Pleated Pre-Filter is designed for increased dirt holding capacity and longer filter life. While some filters require constant replacements, the WaterChef U9000 filters 1,000 gallons on just one filter, which translates into just one replacement per year! To put this into perspective, 1,000 gallons equals over 7,5000 plastic water bottles.

The WaterChef’s Intelligent Monitor is another cool feature of this product as it takes the guesswork out of cartridge replacement. The Intelligent Monitor measures usage, and the LED monitors are built into the base of the system’s faucet. A green light means all is running smoothly, a yellow light means under 10% capacity remains, and a red light means the filter needs to be replaced.

The Premium Designer Faucet (NSF Standard 61 Compliant) features brass construction, a disc valve, and the convenience of LEF indicators built into the base ring. You can choose from four premium finishes: polished chrome, polished brass, brushed nickel, or oil-rubbed bronze.

You can buy an optional Refrigerator Kit (#0071), which is sold separately. With this additional kit, you can easily supply premium filtered water to your sink and refrigerator with a single filter.

With an average .075 GPM flow rate at 60 psi, this filter provides a decent water flow, but some customers report that it is too slow. This filter can run at a maximum pressure of 125 psi.

This BPA-free filter is designed with surgical stainless steel filter housing and made to last. WaterChef stands proudly by the U9000 with a 60-day money-back guarantee and a limited lifetime warranty.

What does the WaterChef U9000 Filtration System remove?

Through employing an activated carbon filter, the WaterChef U9000 removes 75 contaminants including:

  • Lead
  • Mercury
  • Cysts (including Giardia and Cryptosporidium)
  • Chlorine
  • Chloramine
  • Chlorine By-Products
  • Synthetic Contaminants (such as Pesticides and Herbicides)
  • Industrial Contaminants (such as Volatile Organic Compounds (VOCs))
  • Emerging Contaminants (such as Pharmaceuticals and Detergents)
  • Petroleum Contaminants (such as Benzene and MTBE)

Additional removed contaminants are available on WaterChef’s performance data sheet. The unique media formulation allows beneficial minerals (such as calcium, magnesium, and potassium) to remain in the water, making the water cleaner, healthier, and great-tasting.

What comes with the Filtration System?

The WaterChef U9000 comes with everything you need to install it properly so that you have fresh, filtered water right away. The system is compact at only 8.8 x 11.2 x 12 inches and 7.9 pounds, so it won’t take up much space under your sink. With this filter, you will get the following:

  • Premium designer faucet with built-in Intelligent Monitor LEDs
  • Surgical Stainless Steel Housing Assembly with pre-installed Filter Cartridge
  • Intelligent Monitor Assembly
  • Battery (battery is also included with every replacement cartridge)
  • All the tools needed to install, including a T-Valve, tubing, and a wing nut,
  • Installation and User Guide
  • Performance Data Sheet, and Lifetime Limited Warranty

In addition to a Lifetime Limited Warranty, WaterChef offers a 60-day money-back guarantee.

What to Expect with WaterChef U9000 Filtration System

With the WaterChef U9000, you can expect clean, healthy, tasty water anytime you want. No more bottled water will mean you save money and eliminate waste. With the flow rate of .75 GPM, you can expect at least three gallons of fresh drinking water each day.

Customers report that installation is easy and maintenance is even easier. You can basically install this system and then forget about it, since you won’t need to replace the filter for a year, or 1,000 gallons, whichever comes first. Plus, it takes up little space under the sink, another reason to forget it’s even there. When you do need to replace the filter, the convenient intelligent LED monitor will turn red.

The company (and customers) say that this system is ideal for homes, offices, cabins, and RVs since it is small enough to fit under any sink. If you purchase the refrigerator kit as well, you will get fresh water from both your sink and refrigerator with one filter.

Customers also rave about this company’s customer service. WaterChef advertises “5-star customer care,” and they practice this statement with being available Monday-Friday 8 AM to 5 PM (Pacific time) or by filling out a contact form on their website.

While some customers said the initial cost of this filter is a bit high, they also said that that the money they saved throughout the year made the price worth it.

If you’re looking for a high-quality, long-lasting, compact under sink water filtration system, the WaterChef U9000 may be exactly what you’re looking for.

  • NSF certified to remove 75 contaminants
  • WQA Gold Seal Certified
  • High filtration capacity (1,000 gallons)
  • Intelligent LED monitoring device
  • Lifetime warranty
  • Higher initial cost (but money saved in the long run)
  • Slower faucet rate than some competitors
