Thank you for viewing. Pittamask, gray, 2 pieces. Individually wrapped. New face-fitting material adopted. New polyurethane material. Achieves 99% pollen cut (filter performance). Highly breathable and easy to breathe! I used one out of a pack of 3. Because they are individually wrapped, there are no hygiene issues. Please refrain from purchasing if you are concerned or are overly sensitive. Thank you for your understanding.
