So, these issues cause the non-comfortability level of these face shields. These disadvantages are removed by the N95 respirators.
N95 respirators and face shields both have their advantages and disadvantages. However, the disadvantages of both of the protection equipment can be covered by the advantages of both. So, most of the healthcare centers often recommend the use of N95 respirator and face shield at the same time.
