Air treatment system
An air treatment system includes a particulate filtration portion and a disinfecting portion that may be configured within a single enclosure, such as a conduit. The disinfecting portion may include a UV light source that emits UV light onto the interior surface of the conduit that has a photocatalyst surface. A disinfecting portion may include an X-ray portion, wherein an X-ray emitter is configured within the conduit. In one embodiment, the X-ray emitter is configured to emit X-rays along the conduit and toward a photocatalytic mesh that is also configured within the conduit. The particulate filtration portion may be configured upstream of the disinfection portion.
