The KN95MSK disposable safety mask is a great alternative to the surgical-stye (light blue) face masks. These feature a 4-layer design, with two of the layers being a more fine-mesh material. This helps to filter out up to 95% of airborne particles - including pollen, dust, and small droplets.
The KN95MSK is great to keep on-hand for extra protection at work, the grocery store or while running errands. Masks are disposable, meant for single use, and are not washable. This mask is not intended for medical use and not proven to reduce transmission of disease.
