They proudly use charred coconut husks to produce the carbon for all of their filter products. The carbon produced by coconuts contains 50% more micro-pores than any other carbon source. When processing their coconuts, they use a unique manufacturing process that captures and converts gas emissions into useful thermal energy rather than emit these gas emissions into the environment.
