Barbers and many others have been using UV for sterilization of tools for decades... It only makes sense. These methods and devices should be commonplace in hospitals. They should also be used to clean dwellings, planes, vehicles and facilities where Ebola has been present.

This looks promising.

Bit of overkill (No Pun Intended) on the advanced delivery system.

A simpler system would be both cheaper and more desirable from a maintenance standpoint.

UV has been used to sterilize objects and areas for a long time. Filters with UV bathing is the most effective way to sterilize air passing through an air handling system.
