Abstract
An air purification system for a structure includes a first radiation source for generating UV-B and/or UV-C radiation and having an imaginary horizontal plane intersecting with the center of the first radiation source. The system further includes a first screen facing the first radiation source for preventing UV radiation generated by the first radiation source from radiating directly outward from the air purification system into a space below the imaginary horizontal plane. A second screen, facing the first radiation source as well as the first screen, is adjustable with respect to the first radiation source and is at least partially coated with a photo-catalytic material at a surface facing the first radiation source.
