Every time there is a disease outbreak, we get questions about antibacterial face� masks. Which of our mask is the best mask to protect against bacteria and virus? For those with chronic illness, wearing a face mask can be especially important. Many of our clients struggle with a suppressed or weakened immune system due to their illness or medication, making them more vulnerable to contracting the flu or infectious illness. Most dust and pollen masks are great for stopping dust mites, mold spores, and pollens. In the world of microscopic items, these are pretty large. But bacteria and viruses are very small. Regular dust and pollen masks should not be used for protection again bacteria and viruses. Our new Antibacterial face masks are built with a pre-shaped design that offers a personalized fit to cover your nose and mouth. The nanosilver-infused antimicrobial fabric we used helps prevent the growth of bacteria and other microorganisms. The inside of each mask is finished with cotton jersey for softness and breathability.
