up & up™ Disposable Non-Medical Face Masks are made of three filtering layers, providing defense against infections, dust, allergens and pollen. Made with soft non-woven filter cloth, these masks are breathable and skin friendly. The middle layer is made of melt-blown material that acts as a filter and stops smaller particles from entering or exiting the mask, providing more protection than normal cloth masks. These disposable face masks are 10 pieces in a portable airtight zipper pouch.
