I have had one for 4 years and it works. It is installed above the coil
and it is on all the time.

A customer of mine inquired about a UV filter to install in or on a
central AC air handler to kill mold growing inside the cabinet and
duct. Is anyone familiar with these, that can give me any detail on how
and when they are used and work.

What is it's intended function? Is it designed to kill mold, or is it an
air purification system? Do you have the name and model of the unit?
It kills stuff. It does not filter out any dust, pollen, dead bacteria
carcasses, etc. so is usually used upstream of a filter.

OK, it kills stuff. In this case it's supposed to kill mold. My assumption
is that this was recommended by the AC company to kill the mold in the
blower system, and I don't understand how it would kill mold in the duct
work that isn't near the UV light. Again, I'm assuming that if there is mold
in the air handler cabinet, there would also be mold elsewhere in the duct


Hmmm,
Mold causing bacteria is air borne. Actually most germs are.
