Mask Question for Barbara Gill and Others

Barry Irby
>I just got a North 7700 Face mask. Thanks for posting the one you wear. It is comfortable and does not leave me feeling I am re breathing half the air on each breath. Also easy to breath through. My question is, which cartridges do you use for dust? They (Grainer's) sold me charcoal filters (N7500-1 NIOSH OV). Said they were good for dust also. I want to be sure I am using a good filter and the right one.

As an aside, yesterday I had the mask on under my face shield and had shooters ear muffs on also. They are all black. A friend walked in and looked sort of puzzled. I said "I am your father, Luke". He burst out laughing.
