@renbymon #krokodili What kind of mask are you using? I use a 3M 6200 (elastomeric) and when I combine it and glasses I never have this problem. But, when I wear glasses with a disposable N95 I do have this problem.
@ellenor I've been using N95 style masks just for the convenience (adhd). I've got something similar to the 6200 already (JSP Force 8) that I use when woodworking/spray painting but hadn't considered using it anywhere else
@ellenor Just checked the data sheet for the filters; 99.97% To NIOSH Standard For P100 Filter.
