Bottled Water, it's expensive and ecologically damaging. San Francisco just banned disposable plastic water bottles! The Smart Answer: A CB Tech CB-VOC-SB Under Counter Drinking Water Filter System.  Enjoy Fresh, Clean Drinking Water for 6-9¢ a Gallon with No Heavy Lifting!
The Optional electronic capacity monitor that measures the amount of water processed through the drinking water system. An included light indicator installs at the base of the faucet, and lights up when the filter needs to be changed (both the monitor and light indicator are battery-powered; batteries need to be changed when the filter is changed). With the accuracy of the capacity monitor usage may be safely increased to 1200 gallons, versus the normal recommended annual replacement. 

And look for added Savings when you place your CB Tech Water Filter in your Shopping Cart. We'll also include a Stainless Steel Water Bottle with your water filter system purchase.

The CB Tech CB-VOC-SB is an extremely effective drinking water filtration system, for contaminant reduction that installs below your sink and provides convenient access to fresh, clean drinking water with a separate faucet at the sink.

The CB-VOC-SB uses its own specially-designed drinking water faucet that is installed directly on your sink top, requiring little space. And the optional electronic capacity monitor safely allows 1200 gallons of usage. The water filtration unit can set on the cabinet floor with the included plastic stand or be mounted on the cabinet wall. It also may be connected to an icemaker using an icemaker tee fitting, and the system may be converted to a countertop unit with the purchase of a conversion kit (icemaker tee and countertop conversion kit not included).

CB Tech Drinking Water Systems use a solid carbon block water filter cartridge that is considered to be the most effective method for reducing a wide range of contaminants of health concern that may be present in the water. The carbon is compacted into a dense structure, causing every molecule of water to be forced through microscopic pores of carbon, effectively reducing pollutants. The solid carbon block water filter is a replaceable cartridge designed so that it may be easily changed.

Additional advantages of the solid carbon block water filter are that it does not waste water, there is no electricity required, it does not remove essential trace minerals that are beneficial to good health, it does not add salt or silver to the water, and it provides fresh, delicious, healthy drinking water.

The filter housing is constructed of durable stainless steel and the system is tested to meet stringent NSF/ANSI certification standards. With a Lifetime Warranty on the stainless steel housing, a CB Tech® Drinking Water System is easily the most cost-effective drinking water filter available for the money.
