The charcoal for Swift Green Refrigerator Filters is made from coconuts. Coconuts offer a renewable and sustainable source for charcoal and are grown in over 80 countries in the world. The husks and shells are used as the source of charcoal. Activated carbon that is manufactured from coconut shells is considered superior to bituminous coal carbon.
Swift Green Filters utilize a superior type of plastic compared to other filter manufacturers. Swift Green plastics are BPA-free and contain no lead, arsenic, or heavy metals which may sometimes be found in other competing brands. Swift Green plastics are twice the strength of most aftermarket filters, as well as being able to withstand thousands of water pressure cycles without the filter bursting. Swift Green Filters are the only aftermarket refrigerator water filter in the world to receive the WQA Gold Seal of Approval because of the high quality components and manufacturing processes.
