Just a normal surgical mask is probably good enough if you find you can breath well enough with it.
If you wear glasses and they fog, you can use double sided tape in the top of the mask and your glasses will not fog as much.
If you want to wear that N95 valve mask, then just wear the normal surgical mask over top of it.
This system works pretty well and keeps you “legal” and you will be able to breath a lot easier than if you just used a non-valve N95.
thanks. it’s wretched to use them while wearing glasses. i’m seeing a lot of single-layer gauze masks on etsy that are as porous as the transparent mesh ones but look solid. that’s my backup plan.
