Pelletised Activated Carbon™ has an immense mechanical strength designed to withstand the high-water pressures present within canister filters. Pelletised Activated Carbon™ also has improved hydrodynamics due to its larger size. The larger size decreases compression, allowing water to pass through with relative ease. Pelletised Activated Carbon™ will remove organic waste, toxins, phenols (colour), odour, heavy metals, chlorine & chloramine without leaching phosphate, affecting pH, or releasing the molecules it has adsorbed.
