Respirators and surgical masks both help protect health workers from respiratory infections, however there has been a debate about which is more effective and different guidelines provide different recommendations.
A review of the accumulated evidence does not suggest that the N95 respirator is superior to surgical masks.
The authors suggest a randomized controlled trial, evaluating surgical masks and the respirator in a clinical environment to determine which is more effective.
