After removing the filters and straps, for best results you can hand wash in warm water with a mild dish soap. Alternatively, you can run it through a dishwasher cycle.

To preserve the lifespan of the anti-fog coating on the interior of the clear faceplate:

  • minimize touching of this area during hand washing; or
  • choose a short cycle if running through a dishwasher.

Keep in mind that dishwashers perform a more agitative cleaning than hand washing and will cause pre-mature wear of the anti-fog coating on the interior of the clear faceplate. For this reason we recommend hand washing whenever possible and, when not possible, setting the dishwasher to a short cycle.
