If this is what you are referring to, yes they are EXTREMELY tight and small. I think I have a pretty average sized head and it was horribly uncomfortable actually. And yes those are n95

these are too small for my big ass head so might be worthwhile to look at. amazon is usually not a great place for masks due to the possibility of fakes but these are sold directly by the manufacturer. fakes will still be as good as a surgical mask but likely lack the technology that makes them n95.

as a quick primer: n95 is a standard set by NIOSH that uses static electricity to filter out particles that are otherwise really difficult to filter with normal surgical or cloth masks. KF94 and KN95 are similar standards set in Korea and China respectively.

if you find legit ones of anything that meets one of those 3 standards and fits your face you'll be in a good spot.

if you're dealing with a lot of exposure, another couple layers you could add would be cpc mouthwash and xylitol nosesprays. they both have been shown in a few studies to be relatively effective at preventing contracting the disease and even lessening it if you do get it.

I use Xlear nose spray and I think just a crest mouthwash before I leave the house and after I return for just those extra layers of protection.
