3M Health Care offers the 3M Filtro 1900 tie-on duckbill surgical mask that incorporates proprietary filtration media and a rayon outer layer for increased breathability and comfort.
The mask provides off-the-face comfort and unmuffled speech, the company said. The filter combination reduces fogging that results from breathing into a surgical mask, and has a lower delta P, a measurement sought by clinicians performing longer surgical procedures.
