Reduced air flow makes it uncomfortable.

After reading all the reviews, I bought this mask.^M
Thinking this must be the last mask I would want. ^M
But that is not the case. ^M
^M
Good: ^M
- Fits comfortably on face, ^M
- Does not fog up your glasses. ^M
Bad. ^M
- The rubber bands pinched my ears. ^M
- I did gardening with it. and the air flow ^M
was not enough when I was ^M
breathing heavily. ^M
Due to the filter the air flow ^M
is reduced. So after a while I was feeling ^M
uncomfortable, due to lack of air. You cannot ^M
put it on for longer times.^M
^M
You could also get it at OSH.^M
I did not see any mask, which had ^M
a built in fan which will suck the air ^M
from outside, so that you do not have ^M
breath hard to get the air in through the ^M
filter. ^M

Comfortable and Effective

This respirator is comfortable and effective. I wear glasses and they don't fog up. I also get a good seal even with my beard. I've used this while sanding and it made a big difference.

Do Yourself a Favor

Wore safety glasses and the standard paper dust masks together for years, assuming there wasn't really much of a solution to the fogging glasses problem. Finally, the other day, operating a circular saw blindly - not for the first time, I stood up cursing (not the first time). Logged on here and found this thing and all the good reviews. Not as big or weird looking as the picture makes it look. Waited way too long. Power tools and blindness are not a good combination.
