This Cross-sectional Study Aimed To Determine Respirator Fit Of Various Respirator Types And Sizes Through Quantitative Fit Testing On Subset Of Respondents From A Previous Study; The Facial Anthropometry Survey Among Malaysian For The Development Of Bivariate And Principal Component Analysis Facial Panel (NMRR-20-1217-55489). The Main Objective Of This Research Is To Determine Respiratory Fit Between Various Respirator Sizes And Types Based On Malaysian Facial Panel. Specifically, To Determine Fit Test Passing Rate Of Different Respirator Sizes By Categories (S, M & L) Of Malaysian Bivariate Panel And To Determine Fit Test Passing Rate Of Different Respirator Types Based On Malaysian Bivariate Panel. 135 Participants From Selangor, Kuala Lumpur, Putrajaya, Melaka And Negeri Sembilan Were Recruited. Participants Were Randomly Selected Based On Their Facial Cell (1-10) And Size (small, Medium, And Large) According To The Facial Dimensions Measured During The Previous Study. Participants Performed Fit Testings On Twelve Different N95 And An Overall Fit Factor Were Automatically Generated From The Machine To Determine Pass Or Fail Result. The Result Of This Study Showed That Some Models Of N95 Perform Better Compared To Others. Respirators With The Highest Overall Passing Rate Were Pasture PM10, Followed By 3M 9210, 3M 8110s, Pasture F550CS And 3M 1870. Two Respirator Models With The Best Performance Across All Facial Sizes Were Pasture PM10 And 3M 9210. 3M 8110s And Pasture F550CS Also Fitted Well With Small And Medium/large Facial Sizes Respectively. Therefore, Not All Respirator Performed Well And Some Performed Differently Based On Facial Dimension. The Results Showed The Importance Of Conducting Respirator Fit Testing To Ensure Safety For Workers At High Risk Setting.
