Help save the environment with this eco-friendly "green" filter that is an original equipment replacement. Compared to Conventional carbon-based filters, Swift green filter products are environmentally friendly. Conventional carbon filters are produced by a burning process called open pit charring which release pollution and greenhouse emissions into the air. Green filter components are produced with a new technology that carbonizes dried coconut shells in an enclosed self-sustaining system while capturing and converting the emissions into useful thermal energy. The filters are NSF Certified which ensures consumers of drinking clean and safe water. The filters are tested and certified by NSF International to NSF / ANSI Standard 42 for the aesthetic reduction of chlorine taste and odor and nominal particulate class I, as well as to Standard 53 for the reduction of Atrazine, Lindane, Lead, Turbidity, and Cysts. This filter keeps a healthy level of fluoride, a water additive that promotes strong teeth. Swift Green Filters provided complete filtration systems and equipment for residential and commercial uses. Whether you are looking for a system to filter your a single kitchen, the whole house, or your business, Swift Green Filter has a solution to fit your needs and budget.
