"It blocks 99.9% of particulates, making the masks about 4% more effective at blocking particulate material than the N95 masks, according to Bruce Spiess, M.D., a professor of anesthesiology in the UF College of Medicine, who made that calculation based on the manufacturer’s specifications."

The Halyard material, which comes in 4-by-4-foot sheets, is typically discarded after surgical instrument trays are unwrapped and before coming into contact with patients. About 10 masks can be made from one sheet, and an estimated 500 to 1,000 sheets are likely available from UF Health hospitals every day, according to Spiess.

Local seamstress Georgetta Graham has stepped up to help with production and is already sewing prototypes in her home. Soon, kits containing pre-cut pieces of the Halyard material, ribbon or elastic to wrap around the head and a nose wire will be distributed for people to start sewing them in their homes.

 The masks would be returned to UF Health the next day and individually sterilized by ultraviolet light or autoclave before being distributed to health care providers. As people use the masks, they should be either fit tested or pressed as tightly to the face as possible.
