The package contains 2 pieces (a pair). With the new patented design that characterizes the PressTo Check filters, you can easily and quickly check the seal between the mask and your face.

Instructions for use:

• Insert the filters and wear the mask – properly adjust the straps on your head to ensure a correct and comfortable fit.
• Press the front and back of both filters to prevent air from entering.
