OVERVIEW

WaterChef® CR65 Countertop Filter Cartridges

FILTER OUT MORE CONTAMINANTS. SPEND LESS.

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 while delivering up to 600 GALLONS of freshly filtered water with a single cartridge.

This unique formula provides unsurpassed 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 (such as Trihalomethanes)
  • 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)

The result is great tasting water that is cleaner, healthier, and naturally balanced (without the de-mineralization and “flat” taste associated with other water filtration technologies such as reverse osmosis and distillation).

easy filter changes

Stop being nickel and dimed to death by small, costly, and less effective replacement filter cartridges. With WaterChef you’ll enjoy premium quality water at a fraction of the cost. You’ll also enjoy the convenience of a 600 GALLON rated cartridge capacity (That’s over 4,500 plastic water bottles!).

For most households, this translates into just ONE cartridge replacement yearly! (Contrast that with the tiny cartridges found in pitcher and faucet filters. Not only do they eliminate fewer contaminants, but they can require as many as 25 replacements annually.) Plus, fewer cartridges mean reduced waste as well!

Sadly, the water filtration industry is riddled with manufacturers and sellers who make unvalidated and exaggerated performance claims. Rest assured knowing that WaterChef has invested in independent NSF/ANSI testing and certification by one of the industry's most trusted authorities, IAPMO Research and Testing.

IAPMO Platinum SealRequiring the strictest testing and compliance standards, the IAPMO Platinum Seal is awarded to only the most reliable and trusted producers of quality water treatment systems. IAPMO is valued by consumers, manufacturers, retailers, and regulatory agencies across the globe. Trust is what independent NSF/ANSI Certification is all about.

FAQS

How often do CR65 filter cartridges need to be changed?
WaterChef filtration systems are all about performance, style, and value! Not only do you get a system that looks great, is built to last, and performs to your expectations, but one that is also designed to provide up to 600 gallons or one year with a single filter cartridge. That means an average family of four will enjoy freshly filtered water for just pennies a day with the convenience of having only one cartridge to replace per year – easy on your wallet and your busy schedule!
 
How will I know when to replace the filter cartridge?
The CR65 cartridge is rated for a capacity of 600 gallons. With typical usage and water quality conditions the cartridge should be replaced annually. If you have water quality issues, use more then 600 gallons, or notice a tast or odor reucrrence, you may need to replace your cartridge more often.
 
Why do the filter cartridges need to be changed?
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.
 

Why is independent testing and certification so important?

In an industry riddled with unvalidated and misleading performance claims, having a trusted, independent “third party” organization like IAPMO R&T or NSF 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.

 
Does this filter cartridge remove beneficial minerals from the water?
NO. Beneficial minerals (such as calcium and magnesium) pass freely through the system, leaving you with water that is both great tasting and naturally balanced.
 
Does this cartridge reduce Total Dissolved Solids (TDS)?
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 unwanted contaminants while leaving these beneficial minerals in.
 
Does this cartridge reduce sulfur odor (rotten egg smell) in my water?
YES. All WaterChef countertop systems have been independently tested and certified for the reduction of odor, including the rotten egg smell that is often associated with sulfur.
 
Does this cartridge remove fluoride from the water?

NO. While it does have a limited ability to reduce fluoride, it is very dependent upon the pH of the water. If you have 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 the system has been independently tested and certified for fluoride reduction by a trusted lab such as IAPMO R&T or NSF International.

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.

 

Can this filter cartridge be used to filter well water?

YES. While this cartridge 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.
