Do HVAC UV lights really work?

UV lights are effective, but they work in a specific range. They’ll kill organic growths, such as mold or bacteria, but they have no effect on dust, pet dander or other allergens. … UV lights are particularly effective in humid climates, where evaporator coils can easily get wet.

How much does a UV light cost?

Why are air purifiers bad for you?

Air purifiers that use ozone are bad for your health Certainly, these products generate significant amounts of ozone that, if inhaled, can cause long-term damage to olfactory cells and lungs.

Do HVAC UV lights create ozone?

Do UV Air Purifiers produce increased ozone? EPA: According to two studies, operating UV lamps installed in HVAC systems to irradiate the surfaces of air-handling units does not result in increased concentrations of ozone.

Do hospitals use UV light?

A type of ultraviolet light called ultraviolet light C or UVC is helping hospitals cut transmission of super bugs like MRSA that linger in patient rooms and cause new infections, according to a study by Duke Health researchers.

The second best location is below the evaporator coil (if there is room).

Should I sleep with air purifier on?
