- SiempreViernes 7y agoWell, the OP just tested how well masks filter particles, and made comments based on these results. They didn't actually study health outcomes, while the review I linked did find studies of health outcomes but didn't find any statistically significant results. On balance, masks in general usage probably help a tiny bit, but it it's much more important to wash your hands properly, so you're better of buying soap and paper towels.
