I use an N95 while using superglue. Even though they are meant for fumes and not vapors, I don’t even smell it, which means there is little chance of overexposure. I recommended that all of you use at least some type of NIOSH rated respirators when working with any of the chemicals we use or while sanding resin or wood with superglue. And if in doubt always check the PPE section of the SDS.
