Unfortunately, the N95 masks are very uncomfortable.

I really like the Stark vacuum cleaner masks. They have a .3 µm washable poly propylene filter. I’m not sure if they are still available. However, my son relied upon one of those going to college during the pandemic and it did adequately protect him. They are comfortable because the fabric against the face is wicking, but also water resistant, due to the fabric on the outside.

I’ve also been wearing a mask with ventilators, from France, called “base camp.“ This one claims to be N 99. It’s too bad that you don’t rate that one.

Another thing that needs to be paid attention to these so-called nanofilter masks. One of them was called “space mask.“ Another one I think is the Honeywell mask. One thing that worries me about these is that they make my lips tingle. I’m concerned that the nano fibers in them are not stable. I’m concerned that they may have problems similar to asbestos. It would be interesting for someone to look into those also.
