Clear mask could let you see smiles while blocking germs
NCT ID NCT07711145
First seen Jul 17, 2026 · Last updated Jul 17, 2026
Summary
This study tests a new reusable transparent respirator called SEEUS95, designed to provide N95-level protection while allowing others to see your mouth and facial expressions. Healthy adult volunteers wear the mask for short and extended periods and answer questions about comfort, breathability, fit, and how well they can communicate. The goal is to see if a clear mask can be more comfortable and socially acceptable than traditional opaque respirators.
