CR70 Countertop Water Filter Cartridge (includes Battery), 1,000 Gal. Capacity
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 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).
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.
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.
Requiring 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.

WaterChef CR70 Countertop Replacement Filter Cartridge, High Capacity Big Block Filtration, 1,000 Gallon/1 Year 
The water filter industry is riddled with unvalidated and misleading performance claims. Having a trusted, independent “third party” organization like IAPMO R&T, WQA, 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.
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 Research & Testing or NSF International.

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.
