About HaloSource

HaloSource is a clean water technology company, headquartered in Seattle, US with operations in India and China. It is focused on the provision of cleaner, clearer and safer water using its proprietary N-halamine bead technology to clean and purify water, killing bacteria and viruses that may cause disease.

HaloPure provides safer drinking water. In 2009, it became the first new drinking water technology in 30 years to be granted both Manufacture-For-Use and Device registrations by the United States Environmental Protection Agency (USEPA), which is widely recognized as having the world's most stringent performance requirements for water purification. HaloPure® is a unique contact biocide technology that is proven to attack and kill a wide range of harmful micro-organisms and is approved for long-term use in a variety of markets, including the United States.

SeaKlear and StormKlear products use a second technology based on natural bio-polymers to provide water clarification and antimicrobial applications for treating recreational and environmental water; and HaloShield facilitates the binding of chlorine-based bleach to textiles such as sheets, lab coats and towels. www.halosource.com
