Completely agree . Far less heat build up with the half masks as compared to the disposables respirators. I have a couple of your 400 series. Excellent value . I don't think you have to worry about the conversion though, you can't find half masks anywhere now.
I both two pieces and I read the instructions, then I realized better to find it in you tube. For instructions how to put on and off? Would be the same as disposable N95?

Could you demonstrated how to asses the respirator integrity of each piece?

Where can I buy these masks?
