When I fragged lots of Z's and P's for freebies to friends and fellow local members, I would remember the air start getting thick with Zoa Fumes, to the point that I would start getting headaches or lightheadness. So ever since then I would have all windows open venting the air in the house the whole time im fragging and after im done until all the smell is done. I now do this as precaution while wearing breathing mask.

but since i work for biotech I use the one with dual breather and face protection in case I get squirted in the eye.
