WHY MASKS DON'T WORK:
Coughing is NOT the issue.
Large droplets are NOT the issue. Breathing exhales MUCH MORE virus in fine aerosols than coughing. Finer aerosols bypass masks/nose & reach the lungs. Masks NEBULIZE. Solution is VENTILATION not face masks.

"Once direct measurement of particles containing viruses in exhaled breath was technically feasible, most particles (87%) with influenza viral RNA were found to be smaller than 1 μm."

"Influenza viral RNA was detected in the exhaled breath of 92% of adults. The fine particles contained 8·8-times more viral copies than did the coarse ones. Respiratory viruses have been found in both coughs (82% of participants) and exhaled breath (81% of participants)"

👉 "Human rhinovirus was collected more frequently in exhaled breath than in cough aerosols using a filter method." 👈

"The Middle East Respiratory Syndrome (MERS) coronavirus was isolated from seven room air samples from dedicated MERS units in two South Korean hospitals. All seven were positive by PCR and four of seven were positive on viral culture."
