空氣隔離（Airborne Precautions）適用於經空氣傳播的小於 5 微米懸浮微粒（如結核病 TB、麻疹、水痘）。此類微粒可長時間懸浮於空氣中，一般外科口罩無法有效過濾。護理師必須配戴經過密合度測試（Fit test）的 N95 呼吸器，以確保呼吸道完全阻隔微粒，並將病人安置於負壓隔離病房（Negative pressure room）。
Airborne precautions require an N95 respirator because standard surgical masks do not adequately filter small airborne particles like those carrying tuberculosis or measles. The N95 ensures a tight seal and effective filtration to protect the healthcare worker from inhaling infectious aerosols.
