Optrel PAPR Filter
Very good, high quality product. These filters seem a little expensive, but you really don't want to skimp when it comes to safety! I did MIG aluminum for a couple years, and then the fumes started to get to me. Bought the PAPR unit, and noticed quite a difference in how I felt at the end of the day. Would recommend.
