Our Advanced Carbon Blocks have superior performance, discourage bacterial growth, and leave your water tasting fresh, soft and sweet. The pictures below are a typical result of how many impurities are removed from the water supply in less than 1/2 of the filter life (3 months) by light usage for a family of 2.  They are designed to last as long as 8-12 months, but we recommend changing them every 6 months or when you notice a decline in water flow or water quality.  Learn more.
The cartridges come standard with our Classic & Ultra filtration systems.
