Magic trick.

One of the first things I did after getting this unit was invest in some filter adapters. In my shop, I'm not typically dealing with hazardous gases and vapors, so those expensive cartridges are overkill. I really wanted to be able to use my stockpile of cheap pink 3M particulate filters on the new machine.
To echo what others have said, the mask IS too small to fit my glasses comfortably and the hose IS slightly too short. Other than that, seems like a good deal for $75. :thumbup:
