Hairozin technology is a novel, non-electric contact-type bactericide that uses bromine resin technology as the core technology to kill bacteria and viruses. The Herozone filter element contains a new type of contact bactericide, which uses a patented technology that combines bromine atoms with inert polymers. A carrier with tiny appearance and permeability, each gram has a specific surface area of ??up to 25 square meters (scientific name: brominated polystyrene hydantoin. Abbreviation: brominated resin).
However, there are currently a large number of applicants for this technology, and it is not yet certain whether it is unique to Bill Gates. Because there are still many patents covering the element of bromine resin.
