The CDC is full of crap...
The CDC says that, “Cloth masks will not protect you from wildfire smoke.” Yet wildfire smoke particles are nearly twice the size of the coronavirus. If masks don’t protect against wildfire smoke, why does the CDC recommend them for protection against the coronavirus?
It’s way past time for everyone to ditch the mask.
