    Carbon Filters

    Air, Water & Ice's certified carbon blocks are made from roasted coconut shells (not coal). The carbon in our filters works by protecting the membrane from oxidation and premature failure (holes in membrane) that's caused by chlorine breakthrough.

    For convenience, we have more than ten carbon filter products. These include the carbon filters themselves, such as our inline carbon filter, 10-inch 1 micron carbon block, 10-inch 5 micron carbon block, catalytic carbon cartridge, 17-inch Evolution/Merlin carbon pre filter, 20-inch catalytic carbon cartridge refillable, 20-inch 5 micron carbon block, Big Blue carbon filter, and shower carbon filter. Our carbon filter products also include our refill bags. You can opt for our single refill of catalytic carbon, four refills of catalytic carbon (bag), and 30-pound bag of catalytic carbon.
