@hicopd If my asthma is worse, I would have trouble breathing with an N95% mask on, but if I wear a mask as a preventative before I have a reaction to something, I can wear it just fine. I was at a play last night with an N95 on for 2 and a half hours. I had used my inhalers before I went to the show to try to minimize any issues.

Have you ever tried a Moldex mask (https://www.moldex.com/product-category/respiratory-protection/disposable-respirators/)? I need the full face seal of an N100 and found their product had less restriction than any other product I tried. I have worn them for over 20 years.
