HaloSource® is a leading clean water and antimicrobial technology company that is headquartered in Seattle, Washington, United States, and has operations in India and China.

The company is focused on the provision of cleaner, clearer, safer water: Its proprietary HaloPure BR® N-halamine bead technology cleans and purifies drinking water, killing bacteria and viruses that may cause disease. While HaloPure® provides safer drinking water, HaloSource’s SeaKlear® and HaloKlear® products use technologies based on natural biopolymers to provide water clarification and antimicrobial applications for recreational and environmental water. HaloShield® forms the active ingredient that imparts antimicrobial properties to textiles.
