摘要:
A facemask includes an air-filtering portion comprising an air-permeable filtering media; a see-through portion in the filtering media; and a layered portion on each opposing side of the see-through portion. The see-through portion is configured so that, in use, a mouth of a wearer is visible therethrough, and is formed from a transparent film covering a void in, and fixed along its periphery to, the filtering media. The film extends across the length of the facemask, including over the void, forming layered portions of film on filtering media on opposing sides of the clear-portion. A method of manufacture includes removing, e.g., kiss-cutting, the air-permeable filtering media away to form the see-through portion, after layering the film onto the filtering media.
