An actual study on masks this week.

Quote:

Researchers from the University of Massachusetts Lowell and California Baptist University say that masks slow down airflow, making people more susceptible to breathing in particles and a dirty face mask can't effectively filter out the tiniest of droplets.

"It is natural to think that wearing a mask, no matter new or old, should always be better than nothing," said author Jinxiang Xi.

"Our results show that this belief is only true for particles larger than 5 micrometers, but not for fine particles smaller than 2.5 micrometers."

What happened to "the mask isn't to protect you, it's to protect those around you". That's not what this article seems to be hinting at.

"To reach their findings, researchers used a computer model of a person wearing a pleated three-layer surgical mask to track how the face covering affected airflow and how particles passed through. They also looked at how the tiny droplets settled onto the face, in the airway and where they land in the nose, pharynx or deep lung."

Now do it with ****ty homemade masks most. people wear and see how much worse it is.
