Horse Manure - and conflation of two different items of equipment.

The 'masks' foisted upon the public never worked, won't work and can't work against viruses. They don't prevent respiratory infections, there are peer reviewed published studies showing this - and we have the example of Scotland which maintained mandated mask use but had worse outcomes. By and large the whole mask use saga is being revealed as based on no definitive empirical evidence, or risk based analysis of mandated use. Studies such as the above are often conducted to find a conclusion by interests vested in that conclusion. for instance 'Independent SAGE" member - author TG. Author DF receives grants relating to work for Pharma companies up to their necks in profits from Covid related products... etc. Even Fauci has now admitted he saw NO evidence to support mask mandates, lockdowns, and the ludicrously variable 'social distancing'.

Respirators- fully sealed - are a different type of equipment. of course they will work against ingress of particulate matter / gases / emissions / viral particles depending what they are designed for. They are expensive and need training for use, the public were never issued with these nor used them.

This 'report' seems to be trying to bolster some support of a bankrupt official narrative of the Covid period. At a time when many are now acknowledging their support for the 'official narrative' was wrong-headed.
