@s0f0nisba @NatasciaMF the science is well known...since 2021 CO2 levels approaching 3% for more than 15 min. leads to mild CO2 intoxication. https://t.co/NIlU8pikJl
@co2detective5 limit value-weighted average (TLV-TWA). However, the increases in CO2 concentrations did not breach short-term (15-min) limits." The graph shows ~3% CO2 concentration inside the N95 masks. One wonders what happens when masks are worn long
@BarryHunt008 Whatever value you might think N95s provide, you need to weigh that against breathing elevated levels of your own CO2, particularly if you are wearing them for long periods of time https://t.co/1q0swVITjH
@thalesnemo @DonEford The linked study says otherwise I provided an explanation as to why Exhaled breath has 100x CO2 compared to atmosphere Any amount of exhaled breath mixed with inhaled breath will significantly influence the concentration of CO2 inh
