Abstract
An apparatus and method for treating air includes a UV illumination source in a housing and arranged to expose air to UV illumination suitable to inactivate microorganisms. One or more light baffles can be arranged so that UV illumination is incident on an inlet or outlet side of the light baffle. First and second light baffles can operate as a catalyst element and each can respectively have first and second pluralities of air flow channels extending in first and second directions from an inlet side to an outlet side of the light baffle. The first and second directions can be arranged at an angle such that UV illumination is prevented transmission through the first and second light baffles. Air flow channels of a baffle can extend in a direction from an inlet side to an outlet side of the light baffle and can be inclined relative to the inlet side of the baffle by a slant angle of 10 degrees to 45 degrees. The slant angle can be at least the arcsin of the ratio of the flow channel opening size to the baffle depth.
