Background: The available personal protective equipment (PPE) is insufficient to provide adequate protection during high-risk aerosol-generating procedures, and their shortage was reported. The full-face snorkel masks were modified to be used as PPE. However, little is known about their use in medical practice. Methods: The available masks were assessed and compared in terms of safety, comfort, visual acuity, and communication with team members during the aerosol-generating surgical and endoscopic procedures. The masks were compared with a standard option (full-face shield and N95 mask). The score was assigned to each domain to compare the masks. The aim of the study was to assess the modified full-face snorkel masks as PPE during surgical and endoscopic aerosol-generating procedures. Results: Four modified snorkel masks were assessed and compared with the standard option. All masks provided a good seal, comfort, vision, and protection. Communication was the biggest problem and improved after modification. Suggestions for the mask’s selection and on further improvements were made. Conclusion: The modified snorkel masks seem a good alternative to the standard PPE during aerosol-generating procedures. However, additional improvements are still needed. More studies are required to prove the benefits of the modified snorkel masks over the standard PPE.
