The "mask fit test" is conducted to evaluate whether the mask fits closely to the wearer's face. Even if the mask has excellent filter performance, it cannot demonstrate its intended effectiveness if it does not fit the face properly. Therefore, it is necessary to confirm both the filter performance and the fit to the face. Using a dedicated measuring device, the number of dust particles inside and outside the mask is measured to determine the fit factor. If this value exceeds the required fit factor, the test is considered passed. 【Flow of the Mask Fit Test】 ■ Preparation for the fit test ■ Explanation and observation by the fit test administrator ■ Conducting the fit test ■ Recording and storing the fit test results *For more details, please download the PDF or feel free to contact us.
