U9000 Spec Sheet
Design
The stainless steel housing it features serves two purposes, an aesthetic purpose in the sense that it boosts the image of the system, an aspect that might matter to some customers even though it is an under-sink system that doesn’t stick out in the kitchen or room where it is installed, and a durability purpose as it adds to the longevity of the system as a whole, ensuring exposure to impact won’t result in immediate damage.
As you can see in the spec sheet above, the housing assembly dimensions are 9.25 inches in height by 6 inches in width by 8 inches in depth, which means that it won’t take up a lot of space under the sink, so you needn’t worry if that particular space is crowded as installing it won’t present an issue. It even comes with a faucet that measures 11.25 inches in height by 2.75 inches in width by 6.25 inches in depth and which is available in multiple color options to suit the décor of your kitchen.

Performance & Features
The superior performance it provides is sure to change the taste, as well as the smell of the water you consume as soon as you install it. What makes it so optimal is the Big Block filtration technology that employs a solid carbon block cartridge to effectively remove more than 50 common contaminants it encounters in your tap water. This single-filter design makes routine maintenance work less hassle, and it reduces upkeep costs as you won’t have to replace a large number of filter cartridges periodically.
It features the Intelligent Monitor that serves the purpose of eliminating guesswork in regards to cartridge replacement as it announces you exactly when the task is required of you. This way, you won’t witness performance drops caused by a delayed replacement and you won’t risk ingesting impure, health-threatening water by accident.

Filtration
As aforementioned, it uses a solid carbon block cartridge for the filtration process. This means that you must tend to replace a single cartridge, which implies fewer maintenance costs and less hassle with the system as a whole. As it has the capacity of filtering up to 1000 gallons of water before replacement is required, you will have to go through this procedure only once every 12 months or so.
As it can remove over 50 common contaminants that lurk in the water, a difference in the taste, clarity, and smell of the hydrating liquid is bound to occur as soon as you install it. Among the health-threatening contaminants that it tends to remove are included chlorine, cysts, pesticides, herbicides, lead, volatile organic compounds, and more.
However, while it might be able to handle removing a wide range of contaminants, there are exceptions. If you have problems related to bacteria, mercury, or asbestos contamination, we recommend you look into a different option like the CuZn RO-100-50GPD as it features the appropriate filtration media for removing these impurities.

Warranty & Support
We must end on a high note, and the backing provides just that as there is a lifetime warranty backing the system. It is a product built to last indeed, and the manufacturer is well aware of this durable design, agreeing to service it free of charge for as long as you want to use it if you don’t void the terms of the warranty agreement through improper use or installation.
There’s even a 60-day money-back guarantee provided with it, which implies that you can use the system for the aforementioned period and return it if you are displeased with its performance for any reason, moment when you will receive a full refund for your purchase if you haven’t damaged it.
When it comes to customer support, you can confidently rely on the WaterChef team to help you when you are in need as this is a serious company that is renowned for responding quite quickly to customer demands and questions. On their official website, you can find the contact info you need to get in touch with the manufacturer if you are ever in need, providing you with the option to either call the phone numbers put at your disposal or leave a message to which you will receive a response as soon as possible.
