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.


*Roy it sounds as though you want ultraviolet lights for inside the
ductwork. I've seen these used in hospitals, but I don't have any details.
I have also seen the ones used on water filtration units connected to
wells. The idea is that the UV light kills bacteria. Try talking to an
HVAC company.


Thanks John, I don't know who initiated this, possibly the HVAC service
company, and the homeowner is trying to get other opinions. From the
homeowner description, it's just going to be some type of UV light installed
in or on the air handlers. The claim is that there is mold growing inside,
and the UV will kill it. I've worked with the ones on spas, and water
systems, but I've never seen anything like this. It didn't sound like they
were going to be installed throughout the duct, as you describe, which makes
sense to me, just something in the blower. He didn't give me a number, but
said it was wicked expensive. A Google search didn't turn up anything that
was convincing to me. I suppose I should have him get more specifics from
the contractor, so I have something more tangible to look into.
