Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The goal of this observational usability study was to evaluate the comfort, breathability, fit, communication, and user acceptance of the SEEUS95 transparent reusable respirator in healthy adult volunteers. The study aimed to assess whether a transparent respirator could improve the user experience while maintaining the characteristics expected of an N95-equivalent respirator. The main questions it aimed to answer were: Is the SEEUS95 transparent respirator comfortable to wear during both short-duration (30-minute) and extended-duration use? Does the transparent design improve communication and participants' perception of being seen and understood compared with conventional opaque respirators? Can participants breathe comfortably while wearing the SEEUS95 respirator? Does the adhesive sealing system provide a secure, comfortable fit across different facial shapes and sizes? What design improvements would increase user acceptance and long-term adoption? Researchers also collected qualitative feedback regarding facial visibility, social interaction, and overall satisfaction with the transparent respirator design. Participants Healthy adult volunteers, 18 years of age and older. Participants were asked to: Wear the SEEUS95 transparent respirator for approximately 30 minutes during routine activities. A subset of participants wore the respirator for an extended-duration evaluation to assess comfort over longer periods. Complete standardized questionnaires evaluating: Overall comfort Ease of breathing Facial fit and seal Communication while wearing the mask Visibility of facial expressions Perception of feeling "seen" while interacting with others Willingness to wear the respirator in healthcare, workplace, and public settings Overall satisfaction and recommendations for design improvements Provide qualitative feedback through interviews regarding usability, communication, and daily wear experience. Primary Outcome Measures Overall user comfort during respirator wear Ease of breathing Quality of fit and facial seal Communication effectiveness enabled by the transparent design User acceptance and likelihood of long-term adoption Secondary Outcome Measures Participant perception of social connection and facial visibility Skin comfort and pressure points Ease of donning and removing the respirator Recommendations for future design refinements
