    Under-sink filters can be marginally more difficult to install than filters that fit over the faucet. However, they can be worth the effort. The Waterchef U9000 combines a carbon filter, which is what is commonly used in faucet-mounted systems, with a number of other filtering technologies. This means that it improves the taste and smell of water, as well as filtering out a number of other potential contaminants. Heavy metals such as lead can be common in water supplies, as well as chemicals that include herbicides and pharmaceuticals. All water supplies contain some microorganisms that can be dangerous to your health. The Waterchef reduces all these, or removes them entirely. It also reduces sediment, which can help improve the lifespan of appliances and just generally improves the look and taste of the water.

    A common complaint with filtering systems is that connectors and fittings are made with plastic. This reduces the price, but as many pipes and plumbing fixtures are metal, it can lead to problems. The metal fixture cuts into or wears away the plastic, which causes leaks and potentially bigger problems. The Waterchef U9000 uses metal connectors, which means a tighter connection and smaller chances of leaks and water damage. Installation in general with this unit is fairly straightforward, though as with any project, some familiarity with plumbing, and owning some basic tools, is very helpful.

    The Waterchef comes with a dedicated faucet that is supplied by the filter. This faucet can be mounted anywhere, and often will fit the opening on faucets meant for soap dispensers or other additions. It is a good idea to note the size of the faucet, and the size of the opening in your existing sink. A mismatched size can make installing the faucet difficult, and may require more know how. The faucet comes in a variety of finishes to fit the existing decor.

    The filters that comes with the unit are rated for 1000 gallons of water, which the manufacturer estimates will last about a year. There’s no need to guess, however, as there is a digital indicator, which counts down the number of gallons that have flowed through the filter. This allows you to use the filter for its full lifespan, and replace it when it will no longer effectively filter water. This means you get as much work out of the filter as possible. It also means you’re not depending on a dirty filter to clean your water, putting your health at risk.

    The indicator requires electrical power. There is a battery that is included with the filter unit. The Waterchef also plugs into a standard wall outlet. Make sure there is an outlet within a short distance so it can be plugged in.

    The Waterchef U9000 is an excellent filter. It removes many common contaminants, and produces clean, fresh water at a lower cost than buying bottled water and without using a bunch of plastic bottles.
