This is a must for me as i'm biking in the city . I'm using the mask for few months now and i think that it it does the job. The air flow is just enough on the higher fan speed, the mask fits very well on the face . About the actual filtering check the difference in the pic i attached :) One is a filter user for 1 month and the other one is a brand new filter .

It was my last chance to gat a filtering mask but this does not cut it as well. Dont get me wrong, the quality is great but for persons with glases in cold weather just does not work. Maybe for walks but for bike riding and jogging it is out of discussion.
