WaterChef C7000 Premium

C ountertop or under-sink? If a countertop water filter system is what you seek, then we suggest you look into the WaterChef C7000 Premium. This system combines a unique mixture of filter media in a solid carbon block filtration to maximize pollutant reduction in a convenient manner, taking up a small amount of space on the counter.

An NSF/ANSI 42 and 53 tested and approved system , it provides tasty water that is clean and healthy to consume. Moreover, the water it produces boasts a natural balance as it does not lack beneficial minerals that processes like distillation or RO eliminate.

The same quality filtration can be seen in the WaterChef U9000 Premium review here that we recommend as an alternative for those who need a more discrete water purification system.

The fact that it is a countertop model implies that design matters, especially the footprint as it shows how much space it occupies on the counter. Since it measures only 4.75 inches in width by 6.75 inches in depth by 10 inches in height, it won’t take up much counter space, which is great news for those who have small kitchens. It weighs only 3.6 pounds, which makes maneuvering it during the installation process a cinch. The housing is made of durable high impact ABS plastic and stainless steel, and it is accessible in 2 color options – black and white, both variants featuring stainless steel details.

Performance & Features

As mentioned at the beginning of the review, it uses a solid carbon block filtration that contains a fuse of additional filter media to ensure up to 1,000 gallons are purified before replacement is due. This Big Block purifying technology handles removing over 50 common contaminants found mainly in municipality treated water, some of them even lingering in well water, which makes it an optimal filtration solution regardless of your water source.

Mention-worthy features and highlights:
  • Intelligent Monitor: Filter media replacement can get quite annoying as you can never exactly figure out when the time comes for this task. However, the smart monitor it features eliminates guesswork regarding cartridge replacement and simplifies your work by doing so as it measures real usage and lets you know when it is required, preventing premature cartridge.
  • LED indicators: Indicate specific actions and occurrences. The green LED indicates regular operation, the yellow LED indicates that less than 10% of the filter’s capacity remains, which means that you should get prepared to change it soon, while the red LED shows that the maximum capacity has been achieved and the cartridge needs to be replaced.
  • 2-way diverter valve: It allows you to immediately pick between regular tap water and freshly filtered water, helping save filter lifespan as you won’t wastefully consume its capacity.
The 2032 CR, 3V lithium battery needed for the monitor to run is included in the package. When you buy a substitution filter, you will be provided with you a new battery to replace the old one if it has been depleted of power, thus helping save you money.


The fact that there is a single filter that you must replace only once every 12 months or so, depending on water consumption rates in your household, maintenance costs are reduced to a minimum with this system. The major impurities it removes from your potable water comprise:

  • Chlorine;
  • Chloramine;
  • Chlorine by-products – like trihalomethanes;
  • Cysts – like giardia and cryptosporidium;
  • Petroleum contaminants – like MTBEs and benzene;
  • Lead;
  • Synthetic contaminants – like herbicides and pesticides;
  • Industrial contaminants – like VOCs.

Frequently Asked Questions

?Are beneficial minerals removed in the process?
No, unlike other water purification systems, it will not eliminate beneficial minerals like magnesium and calcium. Instead, it allows them to pass freely through the system so that your water won’t only taste good, but will boast a natural balance that helps upkeep your health.

?Can I use it for filtering well water?
Yes, it is compatible with well water purification as well. Although it is specially intended to tackle impurities that are commonly found in municipality treated supplies of water, it does a more than decent job at disinfecting well water too. Thus, it makes for a viable option regardless of your water source.

?Can it be used with any type of faucet?
While it is indeed compatible with a wide variety of faucet types, there is one limitation to it as it will not work with most pull-out faucets, its diverter valve not being compatible with their design. We suggest you look into the WaterChef U9000 Premium as it provides pull-out faucet compatibility.
