WaterChef® CR70 Countertop Filter Cartridges
FILTER MORE WATER 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 and delivers up to 1,000 GALLONS (3,785 L) of freshly filtered water with a single CR70 cartridge!
The unique formula of the CR70 cartridge provides unsurpassed contaminant reduction for a broad range of common tap water contaminants including:
- Lead
- Mercury
- Cysts (including Giardia and Cryptosporidium)
- Chlorine
- Chloramine
- 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).
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 1,000 GALLON rated cartridge capacity (That’s over 7,500 plastic water bottles!).
For most households, that translates into just ONE CR70 filter cartridge replacement per year! (Compare that to the cartridges for pitcher filters, faucet filters, and refrigerators that are so small that they can require as many as 25 replacements per year!) And, fewer cartridges to replace means less waste for the environment too.
The water filtration industry is riddled with unvalidated and exaggerated performance claims, but you can rest assured knowing that WaterChef has invested in extensive third-party testing and certification by one of the water filtration industry’s leading authorities, the Water Quality Association (WQA).
WQA’s independent testing program requires the strictest of compliance standards. They are valued by consumers, manufacturers, retailers and regulatory agencies worldwide. Trust is what NSF/ANSI Certification is all about.
CR70 CARTRIDGE
Big Block™ Filtration
Based on WQA testing data with typical water contitions. Actual performance may vary.
I researched extensively before buying this filter and now I am glad that I did. I have wasted so much money on other filters that broke, needed frequent filter replacement, or out and out didn't do the job. This filter is the best hands down.
I love my filter. The cartridge is easy to install and the water tastes so much better! I love that I can trust it's removing so much from my water without sacrificing the taste. This is a great product that I completely recommend.
This is one of the best investments I have ever made. I have owned this system for over 9 years and still loving it. This cartridge does what it really says it does. Nothing compares to it. I strongly recommend it!! Thank you so much.

FAQS

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 1,000 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!
The C7000 System has an electronic Intelligent Monitor™ that keeps track of how much water has gone through the filter and will alert you when it is time to change the CR70 filter cartridge. You will also get a warning before the cartridge is completely used up, giving you time to order a new replacement 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, leaving you with 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 unwanted contaminants while leaving these beneficial minerals in.
YES. All WaterChef countertop 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 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 WQA (the Water Quality Association), IAPMO, or NSF.
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.
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.
