I purchased a Pro-Flow mask, filter set, and lanyard for my daughter two weeks ago. I’ve always had trouble finding a mask that works well for her. The Pro-Flow was a perfect fit. It gives her mouth and nose full coverage without encroaching on her eyes or popping off her chin and nose when she is speaking. I’ll be buying another one for myself very soon.
