With the new patent pending Force8 PressToCheck filters you can instantly check that you have the correct seal every time.

• Don the Mask – Put the straps and harness over your head and pull the straps to a suitably tight and comfortable fit.
• PressToCheck – Press the front and backs of both filter covers together to stop air from entering through the filters.
• Inhale – No air should come through the mask. Adjust the mask and repeat until it doesn’t. Release when seal is made.
