I've tried the Triton respirator and the Airshield Pro respirator, and neither one of them worked for me.
The Triton fogged up in the winter, was really hot in the summer and didn't blow enough air and the bubble shield distorted the view. It was comfortable to wear though.
Although the Airshield Pro has a flat face shield and you can apply peel off visor covers, and the airflow is more than adequate, the darn thing is just too heavy! It can't be adjusted to fit my face correctly, so it pinches off circulation to my head because I have to tighten the straps too tight.
That leaves me with one more option for a face shield PAPR.. the 3M Airstream. Which is extremely pricey. And there's no place I know of to try one out. Any suggestions?
Not for the first time, I wish Bionic would come out with one. Their face shield is second to none for adjustability and comfort. Maybe I'll just get a Dust-be-gone and make do.
