When used properly, air purifiers can help reduce airborne contaminants including viruses in a home or confined space. However, by itself, a portable air cleaner is not enough to protect people from COVID-19. When used along with other best practices recommended by the Centers for Disease Control and Prevention, operating an air cleaner can be part of a plan to protect yourself and your family.
Visit the Centers for Disease Control and Prevention's website for more information about how to protect your family from COVID-19.
Read EPA’s “Guide to air cleaners in the home” for information on placing and operating a portable air cleaner.
