RESEARCH

Published scientific studies by the USA PNAS Academy of Sciences; USA EPA; Trier University (Environmental Campus) Germany and Canadian Centre for Environmental Health, together with independent studies by Queensland University Professor Lidia Morawska, promote the engineering ideal that by reducing the levels of C02 in an internal space substantially reduces the risk of virus contagion.

Importantly; academic studies recommend maintaining C02 levels below 850 ppm substantially improve the performance environment for students and elite athletes.

LINK BETWEEN INDOOR CARBON DIOXIDE LEVELS AND RISK OF COVID19 TRANSMISSION (SUPPORTING SCIENTIFIC LITERATURER)

Researchers agree that not all respiratory particles settle on the floor fast. Respiratory particles smaller than 5 microns can become aerosols, therefore, can remain aloft for hours, increasing the likelihood of spreading several meters in indoors settings. That was the case of a choir practice in Skagit Valley, Washington State (March 2020), where 53 out of 61 people attending the event, got infected with COVID19, most of them were not even close to the index patients.
