For use in reverse osmosis, drinking water, and aquatic applications, this carbon cartridge is made using a combination of coconut shell carbon and activated bituminous carbon.
A popular option for reducing and removing chlorine, volatile organic compounds (VOCs), heavy metals like lead, mercury, copper, caesium, and strontium as well as lowering water hardness is carbon blocks. They also make drinking water taste and smell better. Water supplied reaches the block's inside as well as its exterior surface. Purified water travels through to the inside of the block, where removed chemicals are stored on the surface.
