I wear a 3M 7502 half face respirator behind my 3M Speedglas autodark mask and it fits just fine. A proper integrated system would be nicer but this setup is safe and works for 1/10th the price. Also if it's not too hot and humid I can leave safety glasses on which is convenient for grinding--just flip up the visor and go for it, no safety squints needed.
