You need a good quality surgical mask plus a mask fitter like the one made by @FixTheMask.
A disposable face mask made out of meltblown polypropylene layer that passes the candle test is likely good.
Why aren't we wearing better masks? Last April, we\u201419 experts\u2015wrote paper on why cloth masks were a good stop-gap measure for COVID. It's just been published in PNAS. Great but... @jeremyhoward and I wrote about our frustration that it's still relevant! https://t.co/tsKHCdQlxr pic.twitter.com/3eoia1B3Ue

2/ Key take away @zeynep @ScottGottliebMD @DrTomFrieden @EricTopol @DrEricDing @ASlavitt: we can all upgrade our masks cheaply. Conditional indoor infection probabilities as low as <0.0001 (0.01%) per hour might be reached with the use of surgical masks and mask fitters alone. pic.twitter.com/bWdWeiZNUS

The neither validated nor standardised hypersensitive RT-PCR test / Ct 35-45 for SARS-CoV-2 is abused to mislabel (also) other diseases, especially influenza, as COVID-19.https://t.co/AkFIfTCTkS

The fabrication of the "asymptomatic (super) spreader" is the coronation of the total nons(ci)ense in the belief system of #CoronasWitnesses.
Asymptomatic transmission 0.7%; 95% CI 0%-4.9% - could well be 0%!https://t.co/VeZTzxXfvT

By the way, who the f*** created this obviously (almost) worldwide definition of #CoronaDeath?
This is not only medical malpractice, this is utterly insane!https://t.co/FFsTx4L2mw
