Mask that is worth its money and more.
I used it throughout the car painting process. From sanding - priming to varnishing - polishing.
Throughout the process, not a single strong smell passed through. It's impressive that while working, nothing passed through, but when I took it off for a break, the smell in the surrounding area was suffocating.
This specific mask will perfectly cover both the amateur and the professional for limited use due to the lack of filter replacement capability.
Easy application, absolute protection, and the certainty of 3M.
