Patent ID: 8003058

Claim:
An air purification device including a reactor arranged to treat aerosol particulates carried in a fluid stream passing through the reactor, the reactor comprising: a plasma chamber arranged to receive a fluid stream there through and to create a high concentration of reactive species within the fluid stream to thereby electrically charge particulates and volatile organic compounds carried in the fluid stream; an electrostatic filter located downstream of the plasma chamber for electrostatically filtering particles from the fluid stream; and an absorptive material positioned within the reactor downstream of the plasma chamber and downstream of the electrostatic filter and exposed to the fluid stream, the absorptive material being arranged to absorb volatile organic compounds carried in the fluid stream and facilitate oxidation of the volatile organic compounds at least in part by exposing the absorbed volatile organic compounds to reactive species in the fluid stream that are generated by the plasma chamber; and at least one electrode arranged to subject the absorptive material to an electric field, wherein the electric field that the absorptive material is subjected to is selected from the group consisting of an applied electric field and an induced electric field and the electric field is arranged to draw electrically charged volatile organic compounds towards the absorptive material.
