The service life of the AirFit F20 mask system is dependent on the
intensity of usage, maintenance, and environmental conditions to
which the mask is used or stored. As this mask system and its
components are modular in nature, it is recommended that the
user maintain and inspect it on a regular basis, and replace the
mask system or any components if deemed necessary or
according to the 'visual criteria for product inspection' in the
'Cleaning your mask at home' section of this guide. Refer to the
'Mask components' section of this guide for information of how to
order replacement parts.
