Universal Masking in School Works. New Data Shows How Well
"evidence is clear...Masks can block and filter the aerosols that carry SARS-CoV-2, and better masks work better; this study supports previous evidence that mask policies in communities prevent transmission...specifically policies in the school setting."
Lifting Universal Masking in Schools — Covid-19 Incidence among Students and Staff | NEJM
During 15 weeks after statewide masking policy was rescinded: “additional 44.9 cases per 1000 students & staff…which corresponded to an estimated 11,901 cases and to 29.4% of the cases in all districts during that time.”

MASKS ARE NOT SIEVES, they can filter aerosols much smaller than the gaps in the mask through microscopic mechanisms.

Alberta Health data & analysis (from Feb 7) shows that schools w/ mask mandates had 3x less outbreaks & adults in those communities had 3x less hospitalizations.

CDC studies show masks lessen school outbreaks
1 study found coronavirus outbreaks were almost 4x more common at public schools w/o mask mandates on the 1st day than at those w/a masking requirement.
Another study found cases increased more in US counties where public schools had no mask mandates:
