Cute, but it might help if you actually were familiar with the links that you have provided. First the “review” of “studies” from over 10 years ago that you linked to was actually related to Personal Protective Equipment provided to firefighters and healthcare professionals used... the fitted quality masks and respirators that I mentioned using during my many years as a Fire Officer and senior Hazmat Officer. Dust masks, bandannas, scarves, homemade nonsense made out of old T-shirts have nothing in common with the equipment that we used that these “studies”.
Thanks for providing more nonsense that makes you look like a complete fool once again.
Quote the exact text that specifies this.
