The Multipure® CB-VOC-SI is a highly effective drinking water filtration system that installs below your sink and provides convenient access to fresh, clean drinking water whenever you want it.

The CB-VOC-SI is designed to be installed under the counter and used for inline applications such as for icemakers, hot water dispensers, water fountains, coffee machines, various restaurant uses, and more. The versatile filtration unit can set on the cabinet floor or be mounted out of sight on the cabinet wall, and it ships to you with easy connect fittings.

Multipure® 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 Multipure® Drinking Water System is easily the most cost-effective drinking water filter available for the money.

Excellent product
I had a Multipure Under Sink filter in the bathroom for years that worked so well I purchased a second one to replace the double filter in the kitchen. The kitchen system had an activated charcoal filter plus a separate particulate filter, but it always left a bad taste in the purified water. The taste from the Multipure is excellent and the new unit is working perfectly in the kitchen.
