CDC warning about smoke..... 9/11/2020

 And here’s @cdcgov warning ordinary (non-N95) masks will do nothing to protect you against wildfire smoke because “they do not catch small particles.”

Fun fact: smoke particles are far larger than #SARSCoV2.

Your mask protects... well, no one.


If my math is correct, wood smoke particles <~1000 nanometers. CV19 virus ~10 nanometers. Smoke particle 100 larger passes through a cloth mask. (O2 molecule ~0.3 nanometers to facilitate breathing and survival.
