How to Use a Mask Filter

Step 1: Ensure you’ve purchased the correct size of filter for your face cover. The PM 2.5 filters sold by Champion System pair perfectly with both the adult and children reusable face masks.

Step 2: Turn the mask over and pinch the filter to fold it in half. We recommend inserting the filter, so the imprinted “PM 2.5” is facing towards the face.

Step 3: Push and pull the filter through the mask and make sure it lays flat.

Step 4: Remove and discard the PM 2.5 Filter after three to four days, and insert a new filter.

  1. A great addition to the masks

    Dominique C. (verified owner)

    The standard masks are great in terms of fit & finish but the filter inserts makes them even better… While providing a very high degree of filtration (that the standard mask cannot achieve), the insert also add a bit of stiffness to the front of the mask that makes it even more comfortable as it prevents the inner soft fabric of the mask to be ‘sucked-in’ against one’s nostrils. This is a great addition to an overall excellent product.
