Swift Green filters aim to provide you with the cleanest and healthiest water filtration for your home and business by making sure the materials we use in our products are eco-friendly while being cost-effective. We are the green alternative to the conventional filter. Our activated carbon is produced using a new technology that carbonizes dried coconut shells in an enclosed self-sustaining system. This process captures and converts the emissions into useful thermal energy. We offer a variety of filters that are compatible with all leading brand refrigerators. Coconuts are a renewable and sustainable source of charcoal. Grown in over 80 countries coconuts have a total production of 61 million tons per year. All those husks are being tossed or burned as waste! We take those husks and use them to create the charcoal for our carbon filters. Coconut carbon is superior to other sources of activated carbon. It has 50 percent more micro-pores for capturing contaminants.
