Where is the best place to put a UV light in a furnace?

The best location to install a UV light if in the A-shape is above, center, and downstream of the coil. This allows the A/C ultraviolet light to shine the most amount of light on the coil, while killing some of the airborne microbes. The second best location is below the evaporator coil (if there is room).

The three primary health benefits of UV exposure are the production of vitamin D, improvement in mood, and increased energy. Moderate exposure to UV radiation is a good source of vitamin D. This vitamin aids in the regulation of calcium metabolism, insulin secretion, blood pressure, immunity, and cell propagation.

Do furnace ionizers work?

Research has shown that furnace ionizers installed as part of an HVAC system, and air purifiers located within the shared-spaces in buildings help to remove viruses and contaminants from the air, including mold, bacteria, and allergens as well. This can help reduce the risk of airborne pathogens causing illness.
