B2 Filters should not be washed for reuse. If you want to clean your facepiece and but continue to use the same filters, ensure that you remove the filters with clean hands and store them somewhere dry and clean until they can be installed into the facepiece again (with clean hands!).
We plan to conduct washability and durability testing to ensure long term effectiveness of B2 Mask.
