Unlike conventional filter masks, Mu2 uses a medical-grade synthetic micro-monofilament material with precision micropore openings (shown below on the right). This material, called "MicroAirScreen", does not degrade, support bacteria growth, or entwine pollen like natural fibers do. The pores of the MicroAirScreen are small enough to prevent passage of the smallest allergenic pollen (about 18 microns in diameter), but are numerous enough to provide unrestricted airflow. You'll never have to replace the Mu2's filter, because it doesn't get clogged, and is easily cleaned with normal soap and water!
The Mu2's MicroAirScreen filter is permanently bonded to its polyester-faced neoprene body, which includes an adjustable Velcro neck strap and an anodized aluminum noseclip. This construction provides rugged durability while insuring a comfortable, customized fit.
Note: The Mu2 SportsMask effectively blocks all dust, pollen, and similar particulate matter. However, it's not designed to block chemical fumes. For work around paint, solvents, or other chemicals, please use a chemical respirator.
