Fits better and is more efficient than the older two cartridge mask I was previously using.
A quality product, good value for the price.
Just got the respirator a few weeks back. Fits well and comfortable. I got it for dust protection when woodturning. So far so good, I will be better situated to comment when I have used it over a longer period.
