Excellent protection for metal work/painting
on May 25, 2008
I use these filters on a 3M 7502 half-face respirator and they are great. I build smokers which require gas-flux (MIG) welding, stick-welding (SGMAW), oxy-acetylene cutting, and a lot of abrasive use (cutting wheels and grinding). Before I started using the respirator and these filters I would expectorate blackened material from the junk I was inhaling but with these and the respirator I can work a full day and not have any discolored discharge; it's great and I'm pretty sure it's going to help me live longer and healthier. I also then paint these smokers with a high-temp paint that I cut with mineral spirits. I made the mistake of painting one once without the respirator and the fumes gave me the worst migraine I've had in years, but when I use these and the respirator I can't even smell the paint/mineral spirits, and I don't get a migraine. I love these things and the whole setup is *cheap*.
