The Maskproof® face mask has a convenient internal pocket for inserting the filter.

The simple steps to follow for the correct insertion, which guarantees the best performance of our product, are illustrated below.


Unfold the face mask resting the external side on a flat surface.

Lift the left flap and insert the filter keeping the "PM2.5" sign on the top left.

Lift the end of the inside pocket, located under the flap, to allow the filter to slide until it is completely extended inside the pocket.

The filter will be correctly inserted if the "PM2.5" sign will be visible by opening the pocket.

In order to ensure the best performance, the filter must be equidistant from the two ends of the face mask.

NB: a package containing two PM2.5 filters is always included in the purchase of each Maskproof® face mask.

For complete information on the use of PM2.5 filters, please consult the technical specifications and uses.
