well as biological contaminants including mold, bacteria, viruses, and allergens in
indoor air. This award-winning technology uses a unique combination UV-C light and

APCO in return duct with
light shining away from
filter media
APCO is usually installed on the supply side
duct just above the air system (upstream of a
humidifier). It can also be installed on the return
side if necessary.
Orient so the air flows past the UV light first
before the carbon. Position the unit so the UV
light does not shine directly on non-uv-resistant
materials (filters, humidifiers, flex duct, etc.).
Ideally the UV light shines on the coil.
For dual systems select a remote UV light
location that shines on the greatest surface area
or the area with the most microbial growth.
Refer to the Optional Remote UV Light section
for installation instructions.
