Respirators. Which one do you use and why? in Shop Safety Posted December 2, 2014 · Edited December 2, 2014 by Ray Hammond Jesus, Hi I use the Trend Airshield Pro and love it. I got it off Amazon and paid significantly less than 600 for it. I wear glasses and can't deal with fogged up lenses that come with the typical half face versions or standard type masks...this full face, fresh air keeps my glasses clean, first of all, and fog free. I clean the filters with compressed air and use them again and again.
