We are excited to be partnering with Kootenay Filters for our carbon filter needs. Kootenay is independently owned and operated out of Nelson BC and they share our commitment to quality and sustainability. That's why we have decided to stock their Green Line Carbon Filters, the only carbon filter made in North America using sustainably sourced and renewable carbon. Kootenay sources carbon for the Green Line filters from charred wood left over after forest fires. It is dusted, screened, activated, and loaded into a galvanized steel housing for a top quality lightweight filter.
