N95 口罩的核心在於「密合度（Fit）」。若口罩邊緣與臉部無法形成完整的密封狀態，空氣會從縫隙進入，導致過濾效能失效，無法阻隔空氣傳播的病原體。因此，每次佩戴口罩時，必須進行密合度檢查（Fit check/Seal check），確保吸氣時口罩會向臉部塌陷，無氣體外洩。這不僅是感染控制的關鍵，更是確保醫療人員安全的標準程序。
The N95 respirator's effectiveness depends on fit. Without a complete seal, air enters around the edges and filtration fails. A fit/seal check is required each time the mask is donned — on inhalation the mask should collapse inward without air leakage. This is essential for infection control and worker safety.
