VO Mask Care Instructions by EVERBRAND August 18, 2020 1 min Disinfecting the Mask When machine washing isn't available, after every wear, use a disinfectant wipe or isopropyl alcohol to wipe down the exterior of the mask. After disinfecting, we recommend placing the mask in the included ViralOff® Bag to 'quarantine' for 4 hours to allow the technology to disinfect any particles that might be on the fabric. Machine Wash For heavier use (in crowded settings, wearing all day), machine washing after every use is optimal. Remove the metal nose bond before machine washing to prevent damage to the nose bond. Machine wash in warm water, on the least intense cycle. Hang to dry.
