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.

Customer? What kind of business are you in? 

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

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.

I think you may want to google for germicidal lamp.  A fluorescent-like 
tube made of quartz glass, which lets UV light through.  Handle with care, 
ie gloves or with clean paper, because fingerprints will damage the tube.  
Don't look into the light, and don't expose yourself (sunburn and worse).  
Used in biological safety cabinets (tissue culture hoods) to keep them 
sterile.  

Glass absorbs UV.

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

Hmm.  Seems to me I'd want it downstream of a filter, to protect the
lamp.  Dust on the lamp may limit the output and effectiveness.
Unless you're going to clean it every month.

Remember, the filter in your system is not to protect YOU from dust,
it's to protect your coil so they stay working longer.

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

Mold is not bacteria.  But yes, I think it would be best to have the UV 
light before the filter, and possibly illuminating the filter to kill 
things before they go THROUGH the filter.  Again, UV is very bad for your 
eyes.  Make sure you have thick glass between your eyes and the light 
when it is on.  Also, the bluish light you can see is not the UV.
