Masks don't stop bacteria, either. Even in a hospital setting with trained users.

In Surgery: Masks Unmasked
Lack of evidence has also plagued surgical masks in their traditional setting, and where their use is still nearly universal: the operating room.

But not for lack of study.

In fact, three large, randomized controlled trials were conducted in the 1980s to determine once and for all if surgical masks actually did prevent surgical wound infection.

Here, where bacteria were the major concern in wound infection, the enemy targets were larger and might not require the fine filtration necessary to keep a respiratory virus away, researchers theorized.

But the trials "showed absolutely no efficacy" for that original purpose, MacIntyre noted.

In fact, the unmasked surgeries had fewer post surgery infections, but not sufficiently statistically meaningful. RCT proves they don't work. Everyone keeps doing it because tradition.
