@Peejay213 @DrZoeHyde Measurement removing 70% of aerosol particles with cheap cloth masks. PFE certification on surgical masks, usually 90%+ is measured at 0.1 microns, about the size of a virus. Actual aerosol particles carrying viruses are much larger.

@drbarnesbangor @crawlings13 @denniskeim @mattyglesias This study shows a 72% reduction in aerosol particles using regular off-the-shelf cloth masks (from the underwear company LOL). Some people use better masks too (though some use worse including bandanas and such). https://t.co/omh8vuGak0

@Barnesbangor博士@crawlings13@denniskeim@mattyglesias这项研究表明,使用常规现成的布面具(来自内衣公司LOL)可以减少72%的气溶胶粒子。有些人也用更好的口罩(尽管有些人用更差的,包括手帕之类的)。https://t.co/omh8vuGak0
