Excellent support for the use of air cleaners (HEPA and #CorsiRosenthalBox) to increase the ventilation rate. It is pretty simple. “Distribute + Dilute + Remove“ to decrease both short-range and long-range transmission. https://t.co/zlnv2RNxmq

It is past time to take steps to clean indoor air. Humans take 22,000 breaths per day. Air is the #1 exposure route to all pollution and pathogens. Why are we not taking the necessary steps to clean indoor air? Public health benefits will extend well beyond COVID-19.(4/4)

— Kimberly Prather, Ph.D. (@kprather88) July 24, 2022

Throughout the epidemic, there have been efforts to make this about personal responsibility—started w masking/distancing—> get vaxx —> ‘you do you’

While we were left to solve an epidemic as individuals, where were the efforts at improving systems, such as upgrading ventilation?

— Abraar Karan (@AbraarKaran) June 9, 2022

It's time to pay attn to indoor air quality, much like we do for outdoor air, or water. We spend 90% of our time indoors, and clean air is essential for our health and wellbeing. With thanks to @linseymarr @j_g_allen @CorsIAQ @kprather88 and @WBahnfleth https://t.co/P3JQTSDTQU
