UV lights and ozone
Canonical HVACentric knowledge for all questions on this topic.
DIRECT ANSWER
UV and electronic air-cleaning products have different purposes and limitations. They do not replace source control, ventilation, filtration, or moisture correction. Avoid products that intentionally produce ozone in occupied spaces. Before installing a device, ask what contaminant it addresses, what independent performance evidence applies, whether it produces byproducts, and what maintenance and lamp or component replacement it requires.
