Martin Coles, CEO of HaloSource commented, "HaloPure was the first water purification technology to be approved under a rigorous standard developed by China's Ministry of Health in April 2011 and we are delighted that the collaboration with Perfect has resulted in another approval. This serves to validate further the potential of our proprietary HaloPure media and continues our strategy to build partnerships with leading companies that are able to deploy products which leverage our technology."
