Original Note:
This meme makes a misleading claim about oxygen levels. Wearing surgical or cloth masks does not impair oxygenation or create unsafe breathing conditions: https://pmc.ncbi.nlm.nih.gov/articles/PMC9715989/ https://pmc.ncbi.nlm.nih.gov/articles/PMC7904135/ The oxygen molecules are tiny (0.0005 microns) and easily pass through mask materials: https://uknow.uky.edu/uk-healthcare/mask-and-breathe-easy-masks-have-no-effect-oxygen-levels https://www.lung.org/blog/covid-masks Specific Evidence: https://www.poynter.org/fact-checking/2021/another-air-quality-monitor-demonstration-fails-to-show-masks-reduce-oxygen-to-children/ https://www.factcheck.org/2020/07/video-presents-flawed-test-on-masks-oxygen-levels/
