Or maybe they are N95. In any event, options from the list were available, but I'm not sure if they still are.

N95s are not a viable choice for the general public, even if they are in abundance. It is for professional applications.
Without fit testing, N95 respirators are not verified as being able to filter out 95% of particulates. In fact an N95 respirator without fit testing is largely ineffective.

The average person will not know this, and even if they did, could not necessarily conduct even a qualitative fit test, if they could get the kits in the first place. Every wearing requires a fit test, and is only good for that model and that specific mask. And fit testing is not intuitive; people need to be trained.
Also: Men with facial hair that crosses the seam line will nullify the sealing effects of the N95.
When a respirator does not fit properly, a portion of the air you breathe can bypass the respirator’s filter and enter your breathing airstream through breaks in the seal of the respirator along your face. If this happens, you may be exposed to harmful pathogens in the environment. In a similar vein, it is important to wear the respirator at all times during the exposure because even short periods of exposure substantially reduces your protection. This all boils down to a simple reality: if the respirator does not form a seal with the face, it cannot provide the expected level of protection.
