Halosource, the Bothell, WA-based maker of low-cost technology for purifying water in the developing world, said it has introduced a new line of clean water products that consumers can use in their homes. The new products—called Waterbird, Waterbird Premium, and Waterbird Elite—will come in the form of powered water pitchers, or a gravity-based water container that contains the Halosource technology for killing viruses and bacteria in water. The company has made its initial inroads in consumer markets in India, China, and Brazil, by making replaceable cartridges that work with devices made by other companies. Halosource went public on the London Stock Exchange a year ago, raising about $80 million for expansion.
