We recommend handwashing your Pollution Scarf. It must be washed very carefully as not to damage the nanofiber filter (wash it softly in water with soap or gentle washing detergent). Do not use bleach, softeners or other aggressive detergents. Do not try the Scarf in a dryer and do not iron it. Let the Scarf hang freely on a line to dry out for 12 to 24 hours.
If you follow these instructions, the Scarf can maintain its filtration efficiency even after dozens of washing cycles (we recommend 50 washing cycles). This methodology was verified by an independent test carried out by the Engineering Test Institute.
