An air purification reactor is described that has a variety of improvements. In one aspect, the air purification reactor takes the form of a plasma reactor. The plasma reactor includes a porous catalyst located downstream of the plasma chamber. The catalyst is arranged to significantly enhance the conversion of reactive species that are contained in the fluid stream before the stream emerges from the plasma reactor. In another aspect, the air purification reactor includes a photocatalyst, and a UV light source that is distinct from the ionizer. With this arrangement, the ultraviolet light that impinges on the photocatalyst causes a photocatalytic oxidative reaction to occur at the photocatalyst that is capable of reducing volatile organic compounds carried in the fluid stream. In still other aspects improved electrostatic filters are described. The electrostatic filters may include one or more insulated electrodes and/or improved dielectrics formed from non-woven fibers. |
