3M is mostly N95 bro, to achieve the criteria to pass the standard for N95, the sealing must be tight. Hence you see many of those N95 are "hard to breathe" and cos the sealing must be goodin comparison to 3M K94, how is this one u mentioned?
that said, 3M now makes a wide range of N95 besides the circular one we used to see during the haze period, comfort level has improved for some models but they are usually quite ex. 3M also made a KN95 (KN95 is China standard, i recall the specs was decent but not as stringent as N95) which I saw is more comfortable than the traditional N95.Zero mask and H-Clean mentioned above are KF94 masks. KF94 is Korean standard, only those made in Korea can be called KF94, and they usually comes in 3D style or 2D/duckbill style. There are a lot of fake "KF94" around in the market, those fake ones are just "3D-style" masks.
KF94 specs are very good also, pretty close to N95, the proper KF94 will be more than enough for daily use. I personally feel that KF94 strikes the perfect balance on comfort, effectiveness and look. However, as with all masks, even the specs are very satki, the fit on your face must be good for it to have that level of effectiveness, and this would require trial and error cos everyone's face is different.
