ViralOff® Mask Care Instructions by EVERBRAND August 18, 2020 1 min The ViralOff® Mask is treated with a high dosage (3%) silver additive that's been shown to inactivate viral particles on the fabric. Antiviral Efficacy (15x Washes) The antiviral efficacy of the mask lasts around 15x cycles in the washing machine. The vicious nature washing machine cycles causes the silver particles to dislodge from the fabric (don't worry -- they're bluesign® approved and don't cause any damage to your skin or the ocean). To extend the life of the masks, we recommend minimizing machine washing by either disinfecting or handwashing the masks routinely. Disinfecting the Mask After every wear, use a disinfectant wipe or isopropyl alcohol to wipe down the exterior of the mask. The outer layer of the mask is water repellent, in order to keep moisture-based particles from penetrating the mask. Wiping the outer layer will work to disinfect any moisture-based particles that remain from a sneeze or cough. After disinfecting, we recommend placing the mask in the included ViralOff® Bag to 'quarantine' for 4 hours to allow the technology to disinfect any remaining particles on the fabric. Handwash If the interior of the mask gets dirty from heavy use, handwash the whole mask with mild detergent and warm water. 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.
