Q. What is an activated carbon block filter?

A. Many activated carbon filters use a granulated form of activated carbon, through which the targeted material flows as through gravel. A block filter is actually made of compressed powdered activated carbon. The smaller individual particles create a larger surface area to volume ratio which significantly increases adsorption kinetics. The use of the powdered activated carbon in a block form provides the ability to add additional functionality using media specifically designed for lead or arsenic. The block filter by design provides additional physical filtration for cysts.

The combination of increased total surface area to volume ratio as well as the additional features that can be incorporated into the block filter make block filters ideal for liquid applications by vastly increasing the amount of contaminants that the filter can remove. Block filters are generally more expensive than granulated filters, but are the preferred choice for many situations.
