It was distributed via emailand social media platforms. Valid responses (402) were analyzed by SPSS V.26. Descriptive statistics and chi square testwas applied and p-value < 0.05 was considered statistically significant. Results:The knowledge of Pakistani HCPs about masks and respirators was satisfactory but practices were not in line withcurrent guidelines by WHO and CDC. Majority reported that they considered wearing mask/respirators in correct way butonly 34% participants knew all steps of wearing a surgical mask and few knew all steps of wearing an N95 respirator.Concepts like fit test, seal and integrity of mask and respirators, hand hygiene, life of one mask/respirator and their reuse were not clear among most of respondents. Conclusion:In this diverse sample of Pakistani HCPs, practice of using face masks and respirators was not as per the guidelines despite adequate knowledge.
