From one of your studies, 'approximately 2%' infection rate is not a failure. Nobody claims 100% protection.
“Our study showed that in a group of predominantly young male military recruits, approximately 2% became positive for SARS-CoV-2, as determined by qPCR assay, during a 2-week, strictly enforced quarantine. Multiple, independent virus strain transmission clusters were identified…all recruits wore double-layered cloth masks at all times indoors and outdoors.”
There is a lot of misinformation;

Masks work. Especially respirator-style N95 masks.
Amid an ongoing pandemic and outbreaks of influenza and RSV caused by airborne viruses, arguing over the virus-blocking power of masks remains one of the COVID era’s signature follies.
Disconcertingly,
despite decades of evidence of their efficacy, some of the disagreement comes from a few in the medical field itself, misusing science and endangering lives.
Most recently
a Cochrane review, which systematically assesses multiple randomized controlled trials, provoked headlines afterclaiming a lack of evidence that masks prevent transmission of many respiratory viruses.
Not for the public, health care workers, or anyone.
“There is just no evidence that they make any difference,” the lead author said in a media interview. This brought an unusual chastisement from the Cochrane Library’s editor-in-chief, who stated it was “not an accurate representation of what the review found.”
