Before you unbox or interact with your B2 Mask, wash your hands with soap and water. Be sure to scrub all surfaces of your hands and in between your fingers for 20 seconds.
Okay, ready to go!
Remove your filters and dispose of them before cleaning the rest of your mask. The facepiece, filter caps, and fabric overlay may be washed by hand using a mild soap or detergent. Alternatively, you can place them all in a laundry delicates bag and machine-wash on the delicates cycle with cold water, laying them flat to dry. Once everything is fully dry, insert new filters and reassemble your B2.
When not in use, the B2 Mask can be folded in half with the overlay straps used to secure it closed. Alternatively, the mask can be left on a clean surface or hung somewhere that is out of the way. Do not store in a sealed container because this prevents moisture evaporation.
