Approximately 30% of health care workers (HCWs) fail the respirator fit test. Evidence suggests that addressing face leaks in the 3M respirator enhances its fit and improves its efficacy. Between March 31 and April 9, 2020, HCWs who failed fit tests for 3M 1860 and 1860S respirators were invited to retest with an adhesive modification of the 3M respirator. Sixty-eight percent of HCWs who failed the fit test with their first-choice respirator passed with a modified adhesive respirator. To increase the efficacy and safety of 3M respirators, ineffective face seals need substantial improvement in design.
大约30%的医护人员呼吸器适配测试不合格。有证据表明，解决3M呼吸器的面部泄漏问题可提高其适配性并增强其功效。在2020年3月31日至4月9日期间，对3M 1860和1860S呼吸器适配测试不合格的医护人员，邀请他们使用经过粘性改良的3M呼吸器重新测试。在首次选择的呼吸器适配测试中不合格的医护人员，有68%使用改良后的粘性呼吸器通过了测试。为提高3M呼吸器的功效和安全性，无效的面部密封在设计上需要大幅改进。
