The Moldex EZ 22 features an adjustable one strap design that is a breeze to pull on and off. This one strap design is the first and only to be approved by NIOSH for the N95. The strap is made of cloth so it stays cooler. An Exclusive Dura-Mesh shell helps the respirator hold its shape and last longer to save costs. It will resist collapsing, even in hot and humid conditions. Designed with a soft contoured nose cushion that reduces pressure points for a comfortable all day fit.
