The Best Waterchef U9000 Review: Get The Most Out Of Your Kitchen Time!

If you have landed on this article, then the chances are high that you must be looking for a powerful under the sink filter. Well, then I am pleased to tell you that you have arrived at the right place.

With the rise of water pollution, filtration systems have become an absolute necessity, and today, we present the Waterchef U9000 review for you. It is known to have amazing performance, filtering, and service throughout its lifetime.

This under the sink filter has made its name in the market quite a bit for several reasons, so let us see what all the hype is about!

Waterchef U9000 Review

The Waterchef U9000 apparently can filter more than a whopping 50 contaminants, which also includes 99% of lead. Not only that, but it also adds back all the required essential minerals you would need in your drinking water.

Industrial compounds like VOCs and other common contaminants such as chlorine, pesticides, and herbicides, among many more, are filtered out.

What is surprising is that, although the Waterchef U9000 might seem like a very compact filtration system, it has an astounding capacity of 1000 gallons, which even some of the bigger boys do not have.

Another surprise for some of you might be that this stainless-steel system with a high capacity comes with a ridiculously low price tag, so you can filter more while spending less!

A stand out feature of this under the sink filter is that it features the Big Block Filtration Technology, which is not commonly seen in the market. Something that might be a bit of a relief for all the customers is that it has been certified and trusted by NSF International, which proves that it is very reliable.

Only one cartridge is used in this filter, which can be seen as an advantage to some extent because it has to be replaced about once a year. The lifetime warranty it provides customers with is a huge bonus and makes it a more appealing option.

Design and Build Quality

As we have mentioned before, this under-the-counter filter has a complete stainless-steel housing, which has a few advantages. Although the filter is not really in sight, the stainless-steel gives it a more premium and shiny look.

Aesthetics attract a good portion of customers because everyone likes to buy attractive things.

Another advantage of this housing is that it helps by leaps and bounds with durability and longevity. When buying something like this product, you would obviously want it to last you a while, and we can ensure that it definitely will.

Also, the Waterchef U9000’s compact form factor is also a big plus point. If the place under your counter is crowded, you still do not have to worry if it will fit because it is quite small for a filter.

You will be glad to hear that this item also comes with a faucet that comes in different colors, so you can choose the one that goes best with your kitchen.

Big Block Filtration Technology

The addition of Big Block Technology to the filter makes its performance superior to most of the other ones you can find. Due to this technology, the taste of the water will also be far better, and the same goes for the smell. It can remove over 50 contaminants from your water, making it safe for you and your family.

Also, the existence of only a single cartridge means that the maintenance costs will be way less than your usual, as it has to be replaced only once every twelve months.

Intelligent Monitor

This is another technologically advanced feature that improves the product’s performance. The intelligent monitor helps to eliminate the cartridge guesswork!

So, now you will be able to know exactly when you will have to replace the cartridge. In this way, you will save yourself from the risk of drinking contaminated water by delaying the replacement of cartridge.


As we have mentioned plenty of times throughout this article that this filter reduces 50+ contaminants and uses a single cartridge. You should also know that the cartridge used for filtering is a solid carbon block.

The high capacity of 1000 gallons will help you to keep the upkeep costs low, as you will have to go through the replacement procedure only once a year. And the removal of the 50+ contaminants such as chlorine, cysts, lead, and volatile organic compounds results in a much nicer tasting and smelling water.

Something worth to be noted is that this item does not filter out bacteria, mercury, and asbestos. So if you have problems with any of these, then you should definitely overlook the Waterchef U9000.


We have to add that the Waterchef U9000 has a lifetime warranty, which shows how confident they are with the durability of their product. They know that it will last a while, and hence, they are providing you with free service for an entire lifetime!
