F1B Full Face Mask


The F1B Full Face Mask (F1B) channels airflow
non-invasively to a patient from a positive airway pressure
device such as a continuous positive airway pressure (CPAP)
or bi-level system, which is intended to provide non-invasive
ventilation for patients with obstructive sleep apnea (OSA).
The F1B Full Face Mask (F1B) is:
• to be used by adult patients (> 66 lb / 30 kg) for whom
positive airway pressure therapy has been prescribed.
• intended for single-patient re-use in the home
environment and multi-patient re-use in the hospital /
institutional environment.


• A full face mask covers on nose and mouth it designed for those who breathe out their nose and mouth. • It can also helpful for people who sleep on their backs or require high pressure settings. • It provides the most efficient and effective amount of air pressure to any individual that needs little more air pressure. • It is perfect for mouth breathe for individual that sleep on their back. • Natural breathing • Water barrier • Built in dry top snorkel system • Anti fog breathing circulation • No jaw fatigue • Better visibility • It protect the wearer from inhaling hazardous vapors, gases and fumes face as well as eye and filter which should be changed regularly in order to ensure effective protection of the wearer.

Benefits & Specifications

• Double-wall cushion for therapy comfort & stability
• Adjustable forehead support i.e, Humanized-design forehead adjustment enables you to find the most suitable level for your forehead and ensures the premium comfort of mask fitting.

• Quiet venting and extra-convenience for oxygen input: Fine and concentrated vent is designed to disperse air gently and quietly. Mean while effectively reduce dead space. Double built-in pods make your connection to oxygen so convenient.
• Multifunctional bilateral ports make the oxygen input or pressure titration as convenient as possible.
• The human optimized design makes the therapy as comfortable as possible.
• It will make discomfort with patients who have facial beard.
• Available in 3 sizes – small, medium and large




Dead space is the empty volume of the mask up to the swivel. The dead space of the mask varies according to cushion sizes but is less than 246 ml.
