I wonder visor opening downwards would provide better protection for most cases and make it more comfortable to wear. That kind of prolonged nose could be designed to slow down the speed of droplets that end and exit. If they were made from hard material they would be easier to clean. (optionally you could add filter with larger volume to make it even more effective)
Surgical- and cloth mask provide low protection to the wearer but give significant protection to others. But people don't wear them properly. You should trim your beard to get good protection, for example.
