A: Hi AP - Great question! You can use a filter of your choice. The product has been authorized by FDA under an EUA for use by HCP as source control to help prevent the spread of infection or illness in healthcare settings and by the general public to help slow the spread of the virus during the COVID-19 pandemic. Thank you for shopping with Target! - Melissa
