Well that's one of their own hypothesis, read the article funkyman X^D
or the Brazilian variant
Edit, you will need to read this data before you post anything about it:

In 2020, number of deaths for Brazil was 1,404.62 thousand cases.
I don't know how to make sense of those numbers, how many different ages can a dead Brazilian have, if total deaths are 1404620 but 25-69 year old deaths are 3086050 and deads over 70 are 3105970 ?
Number of deaths at age 25-69 years 3.086,05 thousand cases Number of deaths at age 70+ years 3.105,97 thousand cases
Good catch, my friend. That's certainly a wrong view in the database that counts data double. Don't look at that too hard, it does not make sense. Looking closely myself, it's a bad database to rely on.I don't know how to make sense of those numbers, how many different ages can a dead Brazilian have, if total deaths are 1404620 but 25-69 year old deaths are 3086050 and deads over 70 are 3105970 ?
I just read it. Apparently (also heard elsewhere) the point here is not the engineering but the fit to face. ACUs work with easier ducts and surfaces than human heads. A disposable surgical mask on the face filters well, but typically leaves holes and pathways for aerosols to be breathed without going through the filter. The cloth mask over the surgical mask just presses it more towards the face and filters a little whatever air skipped around the mask if there are open holes yet between face and surgical mask.Wearing Double-Mask Reduces COVID-19 Spread up to 96.5 Percent, Says CDC
Looks like doubling-up on masks is more effective than we thought.interestingengineering.com
Haven’t read the study yet but am surprised that the filtration doesn’t work better with a surgical mask on top of a cloth one. Particularly when thinking about how ACU filtration systems are designed, there’s usually one or two “sacrificial”, less fine pre-filter(s) before the HEPA filter so that they catch larger particles first and you don’t have to replace/clean the more expensive HEPA filter so often. Also, some cloth masks seem to give a much better fit with fewer/smaller gaps between them and your face than some surgical masks :S
Yeah, we have two causes for steamed up glasses now. The glasses being cold coming from outside and breathing humid air directly towards the glasses thanks to the masks. The first one you can somewhat mitigate by rubbing the glasses with a thin cloth, unless your fingers are very cold also. One could also warm the glasses in one's armpits, but that doesn't really help with the see-through.I've only tried double mask once. I had problem with condensation on my glasses but that happens always to me the first day or two when I try a new model of mask. I eventually learn somehow what to do to avoid it. I guess condensation means some air is slipping around the mask, but I'm not sure.
