Store between -20 & +35 degrees C. Relative humidity less than 85%. For medical use. How it Works: This surgical antiviral facemask has a hydrophilic plastic coating that rapidly absorbs aerosol droplets away from the outer surface of the mask. The first and second layers of the mask are treated with different compounds that inactivate influenza viruses. Fitting Instructions: Prior to Use: Check condition of mask. If visibly damaged, discard mask. Put loops around ears. Adjust mask over nose & under chin. Press forefingers down on both sides of nose. Check for snug fit & comfort.
