WaterChef® Premium Whole House Water Filtration

Enjoy Premium Quality Water for Your Entire Home.

Introducing an EVOLUTION in Whole House Water Filtration!

Powerful Big Block™ Filtration – Removes >99% of Lead and Cysts!

Combining the power of solid carbon block filtration with a unique, proprietary blend of additional filter media and binders, WaterChef’s exclusive Big Block™ Filtration technology provides superior contaminant reduction compared to traditional whole house systems that use granular filter media. By utilizing Big Block™ technology in a whole house filter system, a single EVO100 filter cartridge is able to deliver up to 100,000 GALLONS (378,541 L) or one year of powerful sub-micron level filtration, including: 

  • 99.62% of Lead (both particulate and soluble)
  • 99.95% of Cysts (including Giardia & Cryptosporidium)
  • 99% of Chlorine and Chloramine
  • 98% of PFOA (Perlourooctanoic Acid)
  • 98% of PFOS (Perflourooctane Sulfonate)

Not only does this unique formula provide your entire home with superior contaminant reduction, it also allows 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).

Say Hello to Quick & Easy Cartridge Changes – NO TOOLS Needed!

Easy Filter Cartridge ChangesSay goodbye to the hassle of messy filter media changes and the waste of system backwashing. (Many whole house systems require frequent backwashing, a process that can use over 50 gallons of water per backwash cycle!)

With the EVO100 Whole House System, wasteful backwashing is a thing of the past, and filter media maintenance is a snap – simply replace ONE FILTER CARTRIDGE when the Intelligent Monitor™ LEDs turn red! For most households, that translates into just one system filter cartridge change each year! 

Additionally, our state-of-the art snap-ring technology eliminates the need for cumbersome tools. Homeowners can easily replace the filter cartridge themselves in a few simple steps.

Intelligent Monitor™ - Know When to Replace Your Filter Cartridge

WaterChef's Intelligent Monitoring takes the guesswork out of cartridge replacement, so you will never discard a cartridge prematurely or continue using one that has exceeded its rated capacity. Unlike other systems with simple timer-based monitors, WaterChef's Intelligent Monitor measures water usage and flow rate in real-time, notifying you about remaining filter cartridge life with simple color-coded LED notifications: GREEN, YELLOW, and RED

Intelligent Monitor - Know when to change the cartridge.

Frequently Asked Questions

Q: How often do the filter cartridges in the WaterChef EVO100 System need to be changed?

A: The EVO100 System's EVR1 Filter Cartridges are designed to provide your entire home with up to 100,000 Gallons or One Year per filter cartridge!

Q: How will I know when it is time to replace my filter cartridge?

A: Unlike other systems with simple timer-based monitors, WaterChef's Intelligent Monitor™ measures water usage and flow rate in real-time, notifying you about remaining filter cartridge life with simple color-coded LED notifications. Since actual performance is dependent on your influent water quality, flow rate, system design and application, the EVR1 filter catridge should be changed upon the first occurrence of the following: annually, when the System LEDs turn RED (indicating rated capacity has been reached), when there is a significant reduction in flow rate, or when you notice a taste or odor recurrence.

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 optimal 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 your 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, WQA, or IAPMO 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 beneficial minerals in.

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 for fluoride reduction. If you have questions, or would like assistance, feel free to 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 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.

Product Reviews

  1. Great Product - It makes a difference

    Posted by B.L. on 22nd Sep 2020

    We're very happy with our whole house system. One thing that really stood out was that when the plumbers came to install, they mentioned that our system was far more efficient than any others they have seen. It was really good to hear WaterChef getting praised by professionals. I felt really good about my decision to buy.
