Hydronix CB Series Carbon Block Filter
Formerly Liquatec CB Series

Hydronix CB SERIES CARBON BLOCKS are manufactured with high purity Coconut Shell activated carbon. Available in a wide range of lengths, diameters, and micron ratings our Liquatec blocks provide an exceptional cost-to-performance value. With high chlorine reduction, great dirt-holding capacity, and greatly reduced carbon fines, you will soon make the CB series your carbon block of choice.

Hydronix CB SERIES CARBON BLOCKS are ideal for point-of-use (POU) and Reverse Osmosis applications. These cartridges can be used in a wide range of applications such as residential, food service, commercial, and industrial. The CB Series carbon blocks are great for displacing traditional GAC (Granular Activated Carbon) and PAC (Powdered Activated Carbon) filters in application where high chlorine reduction is needed. Because of your overall lower cost, our CB Series are able to compete with virtually all carbon blocks manufactured in the USA.
