"This novel face mask is designed to be a reusable respirator with a small and highly efficient disposable fabric filter. [...] The probability of virus particle inhalation is reduced using novel air filtration pathways, through square-waveform design to increase filter airflow. Air enters the mask from right and left side filters, while the area in front of the mouth is isolated. Clear epoxy is used for a transparent frame, allowing lip-reading [...]."
