I know, sad right? Dare I ask if you cared to read it? Notice the particle size of Covid-19 versus the filtration of an N95 mask?
Also, it was confirmed in another study that masks around just around 30% effective. Notice that cloth are between 28% and supposedly 80% - which I highly doubt since three masks were to grant you about 80-90% protection.
But please, keep wearing yours. The oxygen deficit inside your mask must be working wonders for those brain cells of yours.
