Why aren’t ozone generators, UV lights or air purifiers on List N? Can I use them to kill the COVID-19?

These are examples of pesticidal devices. A pesticidal device is an instrument or other machine that is used to destroy, repel, trap or mitigate any pests, including bacteria and viruses.

Unlike chemical pesticides, EPA does not routinely review the safety or efficacy of pesticidal devices, and therefore cannot confirm whether, or under what circumstances, such products might be effective against the spread of COVID-19. Accordingly, List N only includes surface disinfectants registered by EPA and does not include devices.

Pesticidal devices, while not required to be registered with EPA, are subject to certain regulatory requirements under FIFRA, including labeling and reporting requirements. Importantly, FIFRA prohibits the sale or distribution of misbranded pesticidal devices, i.e., pesticidal devices with false or misleading claims on their labeling. Selling pesticide devices with false or misleading claims about its safety or efficacy may subject the seller to penalties under FIFRA.

EPA only recommends use of the surface disinfectants identified on List N against SARS-CoV-2.

See EPA's Consumer Guide for Pesticide Devices for more information about the regulation of devices.
