This water filtering system is ideal for all needs, it has great filtering capacities that benefit from new technology, it is easy and convenient to use, and has a great design. Depending on your filtering needs, you may decide to invest in an under-the-sink water filter. Knowing that your water is clean and safe to use is essential, especially if you have small children, whose organisms are more susceptible to the bacteria and viruses that can be found in water. When you have doubts about the purity of your water, the first step is to purchase a water testing kit or have a professional do it for you. That way, you will know exactly what issues need to be solved with the water in your home and will be able to decide what type of filter to install. If you’ve been buying bottled water anyway, you should consider the fact that a home filter will save you a lot of money in time, not to mention eliminating the hassle of always making sure there is water in the house. In this article, we will discuss Waterchef under the sink water filter system.

What you need to know about water contamination is that most of the time it can be eliminated with an under-the-sink water filtration system. While whole-house filters are a more permanent solution, they are more expensive and require professional installation. Most under-the-sink filters can be installed by you, just like the WaterChef U9000 Premium Under-Sink Water Filtration System. That being said, let’s take a closer look at what this filter can do, so everyone can decide whether it would be suitable for them based on their particular needs.

U9000 Premium Under-Sink Water Filtration System

DESIGN: Waterchef under the sink water filter

When you purchase an under-sink filter, the design is quite an important feature to include in your decision process, because part of the filter is visible; the faucet part of the filter has to be pleasant to the eye, or at least match your kitchen to some extent. With the WaterChef U9000, you can choose between four metallic finishes: polished chrome, brushed nickel, oil-rubbed bronze and polished brass. Each of these models looks rather refined and design-conscious, especially the oil-rubbed bronze filter which has a dark opaque color, and can be considered elegant. Thus, the WaterChef is composed of two parts: the actual filter which is installed under the sink, and the faucet part that you will use for filtered water. In that sense, you need to make sure that the filter you purchase is made from resistant and safe metals, like the polished surgical stainless steel that each of these models is lined up with.

Moreover, the system even comes with an electronic LED display that lets you know how long you can use the filter and when it’s time to replace it. Because you also need to compare dimensions in order to make sure the filter will fit with your sink, you should know that this model’s housing assembly is 9.25 inches tall, 6 inches wide, and has 8 inches in depth. As for the faucet, it is 11.25 inches tall, 2.75 inches wide, with 6.25 inches in depth.


Look thoroughly and carefully over the specifications lists that manufacturers provide for their products, no matter what you are buying, because that is where you find out the most useful information. For instance, the filter cartridges on the WaterChef can purify up to 1000 gallons of water, which for average families means you won’t have to worry about replacing it for about an entire year. Furthermore, with the help of the LED display, you will also be warned about replacing the filter in time, so you won’t be caught by surprise and left without clean water. The LED has three color lights, each representing a stage in the filter’s life: when the Green color is on, the filter is functioning normally; when the Yellow LED is turned on, it means the filter is at about 10% capacity, and you can start thinking about ordering a new filter. Finally, when the Red light will be turned on, the filter is no longer efficient and has to be replaced.

The filter works both with cold and hot water, between 34 and 100 degrees Fahrenheit, or 1 and 30 degrees Celsius. The housing system also comes with a special battery which is replaceable after some time. And if you’re concerned about the filtering capabilities of this unit, then the fact that it can retain particles as small as 0.5 microns should disperse some of your worries. The product also got all its NSF certifications, so there are no issues with it not complying with all the standards that it sh

Performance: Waterchef under the sink water filter

We’ve seen some of the specifications and design features, but what about the actual performance of the WaterChef filter system? The patented Powerful Big Block Filtration Technology from WaterChef ensures ideal filtration and long-lasting results while eliminating most contaminants from the water and any unpleasant smells, leaving it with a great taste and all the minerals our bodies need (magnesium, calcium, potassium, etc.). There is also a three-ply pleated pre-filter, which prolongs the actual filter’s life by having increased dirt holding capacities. Here are just some of the contaminants that the Powerful Big Block Filtration will eliminate from your water: excess chlorine and chloramide, chlorine by-products, lead, Giardia and Cryptosporidicum along with other types of cysts, industrial contaminants like VOCs, synthetic contaminants like herbicides and pesticides, and even petroleum contaminants.

Yet, as mentioned above, the filter still allows important and beneficial minerals to stay in the water, so your organism can get all the nutrients it needs anyway. Unlike other types of filters, that are so “powerful” not even the good substances remain in the water, with WaterChef you won’t have to experience that flat taste or develop deficiencies because the water was overly purified.

If you’re also concerned about the environment, just think about all the savings and economy you would make with a filter like this. First of all, a filter that cleans up to 1000 gallons of water and lasts for about a year is almost the equivalent of 7000 bottles of water, plus numerous trips to the supermarket. You will not only be saving money but time as well; most importantly, you will not be affecting the environment so much with consumption of non-renewable resources. Even other types of water filtration systems are not that eco-friendly if you have to replace their filters a few dozen times a year. Thus, besides convenience, you will also lead a more economical and ecological lifestyle.


By now you have learned that the WaterChef U9000 Under-Sink Filter is made from top quality materials such as surgical grade stainless steel, as well as solid forged brass, and ceramic discs for the faucet that ensure its resistance and performance. The NSF certification is a sure way to know that this product is ideal for water filtration, because the NSF is the leading organization in terms of public safety and health regulations.

Moreover, the manufacturer offers a lifetime warranty for this product, which means they are completely trusting in its quality and reliability. If we’re to look at things from a wider perspective, you may have noticed that the consumerist and capitalist world that we live in usually means that any product we purchase is no longer made to be as resistant as it would have been a few decades ago, or more. People are encouraged to buy, buy, buy, to purchase the newer, better model all the time; under the pressure of keeping up with the trends, or just making sure we get our money’s worth, we are convinced to spend even more. So it’s quite rare to find a product (no matter what type, or for what use) that manufacturers fully support and endorse like that. In that perspective, paying the sum of $350 once (not counting the yearly replaced filters) doesn’t seem like that much; it is just an initial investment you’d make for the health of your family, for your peace of mind, and for the well-being of your budget.

Another piece of information that you may find useful is that you can also purchase a Refrigerator Kit separately, so you can also get cold, filtered water there. This kit will utilize the same housing assembly and filter, so the quality of the water will be the same.

Conclusion: Waterchef under the sink water filter

All in all, the WaterChef U9000 water filter seems like a great product for all types of needs and families. It is made from durable materials and easy-to-use fittings that allow you to install it on your own, it has a patented technology filter with NSF approvals that eliminates almost all contaminants from your water, its design is pleasing and complimentary to any kind of kitchen, and utilizing it has multiple benefits that will improve your lifestyle. If you consider it suitable for your needs, then compare it with similar products, and you may be able to find something that pleases you entirely.
