I was expecting something functionally superior

Functional..? NONE of the ridiculous things being worn by the public
at large are remotely functional.
You're wrong
some designs do have filtered vents which (attempt) to safely solve
the condensation problem
Whether they actually work, or not
I have no idea

They are medical masks and should be reserved for medical professionals.

No they aren't. The majority are DIY dusk-masks, and the vent is to let
the moist air out.
