The Honeywell Dual Layer Face Cover with Replaceable Filters come equipped with a hidden pocket designed for convenient filter replacement. It offers adjustable ear loops that allow the wearer to find the correct balance of comfort and fit. The face cover also features a 3-D knit construction that provides a four-way stretch, minimizing gaps and enhancing general comfort in the process. The product is designed to withstand multiple washes and when used with a disposable insert, the face cover is capable of blocking 97 percent of 0.3-micron-sized non-viable particles and 0.1-micron-sized aerosolized particles, the company says.
