How Fan Filter Units Fight COVID-19

In addition to face masks, properly maintained air filters remain crucial in confined indoor spaces to help mitigate the spread of COVID-19 (SARS-CoV-2 virus). Both HEPA filters and ULPA filters reduce the number of microscopic particles in the air, which can keep air safe to breathe in places it’s needed most like hospitals, isolation rooms and crowded indoor areas.

COVID-19 virus spreads through the air on respiratory droplets created from talking, coughing, sneezing, and even breathing. When these activities occur in a populated space with stale air, the likelihood of transmission can significantly increase, as COVID-19 has been proven to remain viable for at least 3 hours lingering in the air or on surfaces up to four meters away from its last host.
