Aleen produces multiple styles of PPE, including ASTM Level 3 Surgical Masks, featuring a three-layer construction, which offers high protection against fluids and airborne particles and bacteria with bi-directional air flow for extra breathability. The NIOSH-approved KN95/N95 respirators boast five layers of protection, including an adjustable nose clip for a secure fit, padded nasal foam, dual straps and a strong, rigid outer shell to prevent it from collapsing on the wearer's face. They are designed to filter at least 98 percent of airborne particles, including bacterial particles.
