Do N95 masks protect against Covid-19? At first, we were told they offered no protection, then we were told they offer limited protection. With the N95 being the main choice for front line health workers and considering the high number of those health workers that have contracted the virus, indications are they are not that effective.

Could a modified snorkel mask be a better alternative? Fitted with a virus filter where the snorkel attaches, the mask would offer complete protection of eyes, nose, and mouth. Because they are designed to go underwater, they could be worn right into a decontamination shower at the end of each shift. Once removed they could be cleaned further and reused over and over. Further modification by connecting a pressurized air supply to the snorkel would give the mask a positive pressure, keeping the virus from entering the mask the same way negative pressure rooms keep the virus in. At a retail cost as low as $50.00 they are an affordable solution to make up for the N95 backlog and effectiveness.
