Gerhard Gerber Posted February 2 Share Posted February 2 I've been sowing the seeds of my own destruction by grinding using a buff or a cigarette to filter the air, my snot tells me both work equally well, the buff just makes me sweat more.... There's one shop selling 3M masks, all I've been able to find that remotely looks quality enough to seal and actually be effective, but they only stock the chemical filters which I understand is meant for painters, no particle filters in sight. My new grinder in hollow grind configuration will throw all the grinding dust directly at me, so I was thinking of forking out for the 3M even if the filter isn't 100% Waste of time and money, or better than nothing?
