Most of the traditional commercially available water purification systems use Granular Activated Carbon (GAC) as a water filtration agent. The highest quality GAC is produced from Virgin Coconut Shell.

A thorough comparison of the sorption capabilities of HRCM and Virgin Coconut Shell 4x6 mesh Granular Activated Carbon (one of the finest activated carbons available on the American market) has been performed by Sierra Analytical Labs in California. The official letter and the test results can be seen here.

The results presented in the table below show the far superior properties of HRCM in comparison to the highest quality GAC. HRCM is more effective than GAC by a factor of 100-400, removing from water the hazardous substances listed below.
The results are expressed in the contaminant’s mass captured by 1 gram of sorbent. The bigger the mass, the more effective the sorbent in filtering the substance from the water .

HRCM - High Reactionary Carbon Mixture
GAC - Granular Activated Carbon
* - Retained Mass estimated due to the high viscosity of the Substance.
