@NeoliberalSnow @MarieSnyder27 CLEAN WATER = CLEAN AIR CLEAN AIR ACT Regulate Indoor Air Quality EVERY sector school to skating rink, fine dining to funeral parlour Both necessary for humans to live, in a society we SHARE AIR

Covid & current indoor air is similar to cholera & sewage in our water (before we implemented modern sewage systems). Follow @jljcolorado @kprather88 for more on importance of cleaning up our air #COVIDisAirborne 6/ https://t.co/mt9Ex5l9oX

My quick demo and explanation of #co2monitoring 🚦importance in guiding your indoor #ventilation requirements. Pls watch & share. 🙏🏽

Am I missing something or are there almost no masks being worn here!? BBC News - Wimbledon 2021: Centre Court crowd gives standing ovation to Covid heroes https://t.co/L1BPm9KyRi

This was in response to my tweet in Jan 2020 saying, "Not sure I believe that coronavirus droplets fall to the ground within a few feet, while measles, chickenpox, and tuberculosis can travel ~100 feet, but why do people think this?" What a wild ride it's been since then.

Katie is the dogged researcher who figured out how the 5 micron error came to be. She is a great follow. And she is finishing her PhD and looking for a job for the Fall. Can't recommend her enough!

"Deep" cleaning is not needed; ventilation and filtration are. https://t.co/hb2l7o4BeT On my recent flight, the airline touted its cleaning procedures for health and safety. Nothing about ventilation and filtration, which is what I wanted to hear about.

This testimony is based on my 12+ years of studying viruses in the air and 30+ scientific papers on the subject, along with many discussions with colleagues (next tweet). Thanks to @jljcolorado @kprather88 for providing feedback on my testimony. /24

Calling the virus “airborne” is the clearest way to convey how it is transmitted. /23

Our letter ( https://t.co/haHo8YGLmJ) calls for CDC and OSHA to issue recommendations and requirements that address transmission of COVID-19 by inhalation of aerosols. /22

Most CDC guidance and recommendations continue to emphasize distancing and surface cleaning, which are important, but less important than using high-performance masks and sufficient ventilation to clean the air. /21

CDC must update and strengthen its guidelines to fully address transmission via inhalation of aerosols at both close distances and farther away. /20
