> Here, we developed an airborne transmission SIMULATOR of infectious SARS-CoV-2-containing droplets/aerosols produced by human respiration and coughs and assessed the transmissibility of the infectious droplets/aerosols and the ability of various types of face masks to block the transmission.
Mannequin heads in a box is perhaps evidence of something, but it has little to do with actual humans who don't live in tiny boxes with masks sealed to their real-world faces.
lol ... yes simulations and models are completely useless (wake up: ALL models are wrong, but some are useful).
If you cannot come up with a better explanation why masks should not work, you are just somebody who's not accepting the current scientific consensus.
So where's your experiment showing the contrary? (With real humans and covid particles?) Where is your evidence?
So we have simulations, evidence that it controls community spread, etc. Every expert that I hear speak out says that masks work. Can you find any virologist working in a lab on COVID who claims masks don't work?
