READ THIS FIRST: a well researched article with REAL facts

Another well researched and thorough review of 14 mask studies.

Groundbreaking study apparently buried by our CDC, with a massive sample of over 90 thousand students in 169 schools nationwide, finds that “distancing, hybrid models, classroom barriers, HEPA filters, and, most notably, requiring student masking were each found to not have a statistically significant benefit.”

UPDATE 8/24/21: Canadian mask study with effectiveness of cloth, blue medical and KN95/N95 masks

The results show that a standard surgical and three-ply cloth masks, which see current widespread use, filter at apparent efficiencies of only 12.4% and 9.8%, respectively. Apparent efficiencies of 46.3% and 60.2% are found for KN95 and R95 masks, respectively, which are still notably lower than the verified 95% rated ideal efficiencies. Furthermore, the efficiencies of a loose-fitting KN95 and a KN95 mask equipped with a one-way valve were evaluated, showing that a one-way valve reduces the mask’s apparent efficiency by more than half (down to 20.3%), while a loose-fitting KN95 provides a negligible apparent filtration efficiency (3.4%). The present results provide an important practical contrast to many other previous experimental and numerical investigations, which do not consider the effect of mask fit when locally evaluating mask efficiency or incorporating mask usage in a numerical model. Nevertheless, if worn correctly, high-efficiency masks still offer significantly improved filtration efficiencies (apparent and ideal) over the more commonly used surgical and cloth masks, and hence are the recommended choice in mitigating the transmission risks of COVID-19.

Here are 44 peer review studies about medical mask and their ineffectiveness to reduce the spread of respiratory viruses . Matter in fact some of these studies demonstrate clearly mask can be very unhealthy to use in a prolonged time-frame and still millions use mask each day.
