Optimize filtration material:
☑️Surgical masks are good
Look for ASTM-rated
✅Respirators are best
Look for standardized filters:
Canadian - 95PFE
South Korean- KF94
Chinese - KN95

Ensure your medical mask is ASTM graded and is at least a grade 2 mask, preferably grade 3 (will ensure better filtration performance of the mask material)
Important to note, ASTM 3 does not imply or guarantee respirator-quality filtration performance.

For kids and those with smaller faces, try the #KnotTuckTape
Turn that rectangle into something more face-shaped. I think taping the corners is important otherwise the tucked in edges often unfold fairly quickly.
