EPA List N is the Environmental Protection Agency's registry of disinfectants that meet the agency's criteria for use against specific pathogens. Products on the list have demonstrated efficacy through EPA-accepted testing protocols and carry registration numbers that verify their approval status.

What does contact time mean for disinfectants?

Contact time is the number of minutes a disinfectant must remain wet on a surface to kill the target pathogen. If a product lists a 10-minute contact time, the surface must stay visibly wet with the disinfectant for the full 10 minutes to achieve the claimed kill rate. Wiping it dry early means the product may not work as labeled.

Should I trust this list over EPA.gov?

No. Use this as a shortlist for education, then confirm the live EPA List N entry, registration number, and labeled contact time on EPA.gov before you specify a disinfectant.
