This face mask product is designed to withstand multiple washes, and when used with a disposable insert provides the wearer with an extra layer of mouth and nose coverage beyond a common cloth face covering. The filter insert has been shown by a third-party testing facility to block up to 97% of 3-micron-sized non-viable particles and 0.1-micron-sized aerosolized particles. This mask provides the ultimate comfort with a seamless three-dimensional knit that provides a 4-way stretch- minimizing any gaps and enhancing overall comfort. The adjustable ear loops and nose clip allows you to easily adjust the mask to your comfort. The filters are hidden by pocket designed for easy Honeywell filter removal and replacement. And since the mask has a contoured design, it stands off the face to enhance breathability making it feel as though you aren't wearing a mask at all
