All SumiBall products use activated carbon at the core for a highly effective natural filter to bring purity to the home and garden.
Activated carbon is charcoal that has been treated with oxygen at very high temperature, opening up millions of tiny pores between the carbon atoms; this process results in highly porous carbon that has a surface area of up to 2,000 square metres per gram. Activated carbons are widely used to adsorb pollutants from gases or liquids; the pollutants attach by chemical attraction, and the huge surface area of activated carbon gives it countless bonding sites. As particular chemicals pass next to the carbon surface, they attach to the surface and are trapped; activated carbon is extremely good at trapping carbon-based impurities ('organic' chemicals), as well as other chemicals such as chlorine.
The unique ceramic shell makes handling clean and easy, and the ball shape increases benefits in all applications by maximising exposure to air and water in the environment. Just like a water filter in the home, the active carbon core of each Sumi traps the unwanted harmful bacteria that cause unsightly algae, unpleasant odours and plant disease. SumiBall products are made with carbon from sustainable sources of cedar and cypress hard woods, recognised as a highly effective natural anti-bacterial filter. The carbon traps toxic compounds such as formaldehyde and ammonia in a complex microscopic lattice and can absorb liquid to over 75% of its volume.
