Can the bacteria and viruses trapped on the AMBREEZE filter, multiply and escape back into the air?

No, viruses require living cells to reproduce, and both bacteria and viruses require water
and nutrients to reproduce. Most pathogenic bacteria and viruses are destroyed due to
dehydration caused by the airflow through the filter. HEPA filters also have a long history of
use in applications like hospital isolation wards, to prevent the spread of airborne microbes.
