When exiting the mouth of an infected individual, the virus latches onto particulates of various sizes in the air.

It is more difficult for masks to catch smaller particulates hence, the importance of efficiency ratings.

Used a PurpleAir Sensor to measure the particulates.
Air Compressor for the "simulated" breathing
3 different masks: Surgical, fabric, N95
Psurgical = 0.9473
PN95 = 0.0255 ❌ Reject Ho
PCloth = 0.2415
Test 2, Ho: Population mean concentration (μu)≤Proposed mean concentration (μo)
HA: Population mean concentration (μu) > Proposed mean concentration (μo)
PN95 = 0.0127 ❌ Reject Ho
Psurgical = 0.9473
