• New elastomeric half-mask respirator (EHMR) models without exhalation valves (EVs) or with exhalation valve filters (EVFs) are facilitating expanded use in health settings to reduce workers’ exposure to airborne hazards while acting as source control to prevent pathogen spread. The physical comfort of new models has not been assessed in comparison to previously used EHMRs with EVs. Researchers assessed 1,962 health care and emergency medical service personnels’ self-reported adverse experiences from 2 cohorts while wearing EHMR models with EVs (cohort 1, n = 1,080) and without EVs or with EVFs (cohort 2, n = 882). Fisher exact test identified differences between the cohorts accounting for organizational factors when possible. Cohort 1 respondents experienced communication challenges and discomfort when wearing the EHMR > 1 hour statistically significantly more often than cohort 2. Cohort 2 respondents reported statistically significantly more instances of difficulty breathing, moisture buildup, being uncomfortable to wear < 1 hour, and being uncomfortably warm. Discomfort is prevalent among end users and more often among those wearing EHMRs without an EV/with an EVF. As EHMR research and development advances, prevalence in use may increase for emergency and routine situations. Organizations may not only need guidance about respirator selection but also model-specific selection. •EHMRs are suitable for use in a range of healthcare and emergency response roles.•Occupations may experience different types of PPE interference based on tasks.•Users from organizations with EHMR experience were less likely to express discomfort.•Cohort 2 experienced excess warmth and moisture buildup 2 times more than cohort 1.•EHMRs may be stockpiled for routine use and emergency preparedness and response.
