Unless it's drawing "products" from a container to be dispensed, there's
nothing to clean downstream air. Even if there was cleaning performed, where
is the stuff "cleaned off" going. Some sort of extractor before the air is
discharged?

If you read the Kansas report, it is written by what appears to be a
distributor of their product. It gives intake counts well above what they
list as typical, and output counts well below what is considered typical.
The person writing the report does not list any qualifications. UVX probably
means that their lamp emits multiple wavelengths of UV light - as do all
UV-C lamps.

Think about this for a second..... There are devices that can play games
with input waveforms to reduce apparent power for motors, but they only work
with a single motor, and generally result in reducing the speed of the motor
to more closely match what is required at the time. Anything that claims to
reduce power consumption of individual devices by doing something to bulk
power has got to be snake oil.
